Masaomi Kida (紀田 正臣, Kida Masaomi) is a resident of Ikebukuro and Mikado Ryuugamine's best friend from childhood. He is the one who encourages Mikado to come to Ikebukuro to attend Raira Academy. Masaomi is enthusiastic about picking up girls despite repeated failures and acts as the comedic foil to Mikado and Anri in the early portions of the series.
Masaomi's usual attire consists of a white hoodie, black jeans and a pocket chain, and black sneakers. Throughout the anime, he is often seen wearing the Raira uniform jacket over his hoodie with brown sneakers. During his time in the Yellow Scarves, he wore a black jacket with a white shirt along with his gang's titular accessory. He has dyed light brown hair, depicted as blond in the anime, and ear piercings.
Masaomi has a very friendly, enthusiastic, and outgoing personality, and is almost always seen fooling around, smiling, making bad jokes, teasing his friends, and hitting on girls. He is shown to care deeply for his friends, having to act as a sort of big brother for Mikado as he adjusts to life in the big city and going to great lengths to protect those who are close to him. When Mikado first sees Masaomi in Ikebukuro, after years of separation, Masaomi's bubbly personality and bad jokes are what convince him that the man greeting him is indeed Masaomi Kida. As the series progresses, it is revealed that Masaomi's enthusiastic, happy-go-lucky demeanor is actually a mask of his true, much less secure self. He appears to agonize over major choices much more than any other character in the series, although he falls short of being paralyzed by his fears, still being able to make important decisions when necessary. He also demonstrates a feeling of responsibility for those close to him, taking attacks on his friends very personally. Despite appearing carefree, his experience as leader of the Yellow Scarves makes him painfully aware of the realities of life, and his greatest fear appears to be allowing himself or his friends to "cross over to the dark side," preferring that they stay completely away from the color gangs even to the point of being ignorant of them. As the leader of the Yellow Scarves, Masaomi has also demonstrated a ruthless demeanor when confronting his men. He showed no hesitation at all when physically or verbally berating other members who went against his orders. Even members who were older than Masaomi seemed genuinely intimidated by him.
In terms of abilities, Masaomi is shown to be a proficient street fighter, being able to easily incapacitate several of Horada's henchmen before being overwhelmed by sheer numbers.
Masaomi founded the Yellow Scarves when he was in middle school, intending it to be a playful sort of team. As the Yellow Scarves grew, they became one of the notorious 'color gangs' that went around the city, occasionally fighting each other. However, as the gangs grew older, one of their rival gangs, the Blue Squares, began to get serious, stretching the boundaries of a typical gang of middle schoolers and becoming quite violent. The Yellow Scarves naively expected a fair battle, but the Blue Squares allegedly played dirty and only picked fights that they could win, devastating the Yellow Scarves.
It was during the Yellow Scarves/Blue Squares war that Masaomi met Saki Mikajima, a girl who recommended him to an informant named Izaya Orihara to help him fight his wars. Masaomi was, quite reasonably, put off by Izaya's personality and found it difficult to trust him, but Izaya's advice was sound, giving the Yellow Scarves intel on Blue Squares hangouts and teaching them how to fight. The success Izaya brought to the Yellow Scarves led Masaomi to unintentionally become dependent on him for help, and Izaya continued to provide information until the Blue Squares was cornered and about to be finished off.
Thanks to Izaya, Masaomi and Saki saw each other and talked a lot, eventually deciding that they were, in fact, dating. Saki was kidnapped and tortured by Ran Izumii and the higher-ups within Blue Squares in an attempt to lure Masaomi out and end the Yellow Scarves. Masaomi sought Izaya for help, but Izaya would not answer his phone, and Masaomi was left helpless and unable to save her. Fortunately, Kyouhei Kadota and his group within the Blue Squares, who were disgusted by the gang's lack of honor, betrayed their gang and saved Saki, though with two broken legs and no family she had to be hospitalized for a year.
Masaomi left the Yellow Scarves after the war and vowed never to go to "the dark side" again. However according to Izaya, the incident made Saki his "god," with her becoming the embodiment of his dark past from which he could never escape.
It was through chats with him that Mikado Ryuugamine decided to come to Ikebukuro, lured in by the sense of excitement and fun that his friend Masaomi described. Masaomi left out the harsher details of his life in the big city, including his gang experience, as he believed it to be better that Mikado would never find out about them. Hearing about how bored he was with his small town life, Masaomi encouraged Mikado to join him and enroll in Raira Academy.
Dollars/ Mika Harima ArcEdit
Masaomi first appears to give Mikado an official welcoming to Ikebukuro. Despite their time apart, the two of them get reacquainted very quickly as Masaomi shows him around. He introduces Mikado to a few of the more notable residents including Simon and Kyouhei's gang while also warning him about a few of the more dangerous individuals such as Shizuo and Izaya.
The next day, he congratulates Mikado about how he and Anri were elected as class representatives, playfully teasing him about his apparent attraction to her.
Later he and Mikado come across Anri being bullied and, just as they try to form a plan to step in, Izaya interrupts them by pushing Mikado into the fray. After things settle down and Izaya chases the bullies off, he asks Masaomi to introduce him to his friends. Masaomi reveals that he went to Raira Academy because of Izaya. They are interrupted once again by the arrival of Shizuo Heiwajima who attacks Izaya with a trash can, to Masaomi's excitement. Mikado takes Anri's hand and runs, leaving Masaomi behind.
The next day, Masaomi, Mikado, and Anri go to the park where he buys ice cream for the whole group. He and Mikado then listen to Anri while she talks about her missing friend, Mika Harima. That night, he gets called over by Mikado because Mikado bumped into a girl on the street and does not know what to do.
Masaomi goes over to see the girl and to get a proper explanation of what was happening. Mikado explains that the girl was being chased by the Black Rider, but Masaomi is more than skeptical, remarking that others would not believe his story either. He drives this point home the next day as he blurts out everything Mikado had told him the night before, intentionally telling the ridiculous story to several classmates so they would not believe it.
Knowing that Mikado was interested in the rumors about the Dollars, Masaomi takes him to the roof to see if Ryo Takiguchi is a part of the Dollars. Masaomi asks the question straight out, which Mikado yells at him for. Ryo tells them the truth, and says he is in the Dollars, explaining his view of the group in the process. At the end of the school day, Masaomi ends up in a big fight at the student council meeting, so he cannot walk home with Anri and Mikado.
The next day he tells Mikado about the Dollars meeting that happened the night before and that according to the stories, the Headless Rider really has no head. At lunch, Masaomi hits on Anri, causing Mikado to punch him in the face.
Masaomi sees Anri being harassed by her teacher, Takashi Nasujima. Masaomi steps in, pretending to joke about telling the teachers about Nasujima's actions. Nasujima attempts to brush Masaomi off until he pulls out a camera, proving he was serious about going to the teachers if he kept harassing Anri. Masaomi later appears to, once again, stop Nasujima from harassing Anri, this time dropping the name Haruna Niekawa to scare him off. Masaomi explains to Anri that Haruna was the previous student that Nasujima was fixated on before she was forced to transfer.
Yellow Scarves ArcEdit
After seeing Anri in the hospital because of the slasher, Masaomi rejoins the Yellow Scarves as their leader. He declares that the Yellow Scarves' current objective is to hunt down the slasher and to search for more info on the Dollars, crushing them as well if the slasher is operating from within the Dollars' ranks.
After musing about his past, Masaomi hears one of his guards interrupt the meeting with the news that someone is spying on them. Masaomi and several other gang members run outside and search for the girl. When she is rescued by the Black Rider, one of the members throws a metal pipe at them, and the girl cuts it in half with a katana, proving herself to be the slasher. Remembering that the Black Rider was at the Dollars meeting, this cements the Yellow Scarves' belief that the Dollars and the slasher are allied with each other.
The next night, Masaomi visits Saki in the hospital to talk to her about recent events as Saki mentions that she sees him from her window all the time. The conversation brings up bad memories, and Masaomi leaves, with Saki cryptically saying she knows he will come back.
Masaomi visits Kyouhei and his crew to talk about how to handle the situation with the Dollars and Yellow Scarves. Kyouhei simply tells Masaomi to follow his gut, but Masaomi refuses to accept such a vague answer. As the conversation gets more heated, Simon attempts to diffuse the situation but is ignored.
Dennis gets angry because their talk is scaring the customers, so he throws a knife into the private room, sticking it into the wall, and tells them to stop talking about such a violent topic. Masaomi leaves and reluctantly seeks help from Izaya, who reveals that Mikado is the leader of the Dollars. Masaomi tells his men to stop the attacks on the Dollars, but the attacks only grow worse.
When Horada and his thugs go after Anri, Masaomi grabs her and drags her into an alley to help her escape. He confronts her about being the slasher and working with Mikado, the leader of the Dollars. He accuses her of manipulating him and Mikado, causing Anri slap him in the face and run away. He gets a call from Horada saying that he knows that Mikado is the leader of the Dollars and that he has taken control of the Yellow Scarves. He also tells Masaomi that he is weak and no longer needed before hanging up. Furious with himself and the situation, Masaomi makes the decision to run to the Yellow Scarves headquarters alone to take care of Horada and the gang.
Simon sees Masaomi and notices his grim demeanor. He tries to dissuade Masaomi from doing anything reckless, but Masaomi cheerfully waves and and keeps running. Masaomi confronts Horada at the Yellow Scarves headquarters, where Horada reveals that the only members left in the Yellow Scarves are the former Blue Squares loyal to him. The members of the original Yellow Scarves still loyal to Masaomi have been attacked and hospitalized. Horada throws a crowbar at Masaomi, who takes a hit to the head. Bleeding, he picks it up and defends himself from Horada's attacking thugs. He manages to hold them off while simultaneously advancing toward Horada. Just when Horada is about to shoot Masaomi with his gun, a Yellow Scarves member under Anri's control stops him, stating that 'Mother' wouldn't like it if Masaomi were hurt. Soon after, Anri slashes the door to the hideout with Saika and Mikado rides through on the back of Celty's bike.
With Anri, Mikado, Masaomi, and Celty all in the room, Horada orders the rest of the Yellow Scarves to kill them all, but Kyouhei's voice shouts out, and a large number of Yellow Scarves begin attacking other members. It is revealed that about thirty of the members who showed up that night were actually Dollars members whom Kyouhei and Saburo called in to help. Amidst the chaos, Horada lets slip that he was the one who broke Saki's legs. Masaomi, enfuriated, punches Horada in the face before falling down unconscious. Mikado then holds him up and asks him to wake up. He wakes up, telling Mikado that he does not want him to "go to the dark side" before falling into unconsciousness again. Kyouhei tells Mikado to take Masaomi to the hospital, promising to take care of the rest of the former Blue Squares members.
Masaomi wakes up in the hospital, and Anri and Mikado are relieved that he is alive. They leave to let Masaomi rest. Later, Saki comes in and tells him that her being kidnapped by the Blue Squares two years prior was part of Izaya's plan and something she had let happen purposefully. The two of them confirm their feelings for each other, and when he is better, they run away together.
Masaomi joins the chatroom as Bakyura, giving Taro Tanaka subtle hints about his well-being and Kanra death threats.
Masaomi and Saki are working as field agents for Izaya, gathering information for him to use as a way to support themselves. Recently, Masaomi and Saki were asked to gather information on Yodogiri Jinnai. Masaomi is suspicious about the job due to the fact that it was given so suddenly and the fact that the area they're supposed to search in is very remote and isolated. Masaomi is also unsettled due to the fact that there aren't any real computers in the town they're heading to and he can't log into the chat room. Saki says that he's become too addicted to the internet and also wonders why Masaomi can't simply just visit them instead of just going on the chatroom. Masaomi replies that he just can't see them because he fears that they won't accept him if he did go back.
Dollars and Blue Squares ArcEdit
After they return from their trip, Kida logs on to the chatroom to catch up but no one is on. He tries to check the archive history but finds it empty as well. He logs back on again the next day and asks Mairu and Kururi for an update on what he missed. The twins are confused as they remember Masaomi being on the day before. Kida is alarmed about this and asks if Taro Tanaka was on as well. The twins say yes and Kida immediately makes the assumption that his account was hacked and also has a good idea as to who is responsible.
Masaomi calls Izaya and asks him what he said to Mikado in the chatroom and why he hacked into his account. Izaya taunts Masaomi, asking him why he doesn't just talk to Mikado about it and telling him he is being a coward. The insults hit a little too close to home and Masaomi lashes out at Izaya who promptly hangs up on him, saying he doesn't like being yelled at.
A few hours later, Saki asks Masaomi if he was lonely. Masaomi tries to deny it, saying that he has her. Saki sees through the lie and says that while she can be Masaomi's lover, she can't be his friend in the same way Mikado and Anri can. She says that, from the way he described them, it would be impossible for his friends to abandon him and even if they did, She would be there to help him back up. Saki goes on to say that if Masaomi's friends are in danger, then the only person who can, and should, help them is Masaomi himself. Reinvigorated by Saki's words, Masaomi packs a few changes of clothes and heads out to Ikebukuro to help Mikado.
Masaomi isn't seen until much later after Mikado tried to apologize to Chikage. He see's Mikado break down in tears and immediately stops himself from calling out to him. He realizes that, with the way he was right now, he wouldn't want to be seen in that state by Masaomi. Masaomi turns and leaves, deciding to re-introduce himself after Mikado had recovered.
Masaomi learns about Mikado and Aoba going around and expelling dollars members and decides to investigate. Masaomi learns that Mikado was chasing after Ruri Hijiribe's stalker and decides to intervene before he could do anything rash. When he returned to Ikebukuro he says sorry to Shizuo, but Shizuo just pokes him and Masaomi flies in the air and is out cold, but wakes up after an hour.
Later he arrives too late and sees that Mikado has already been beaten severely by Adabashi Kisuke. Masaomi manages to get the jump on Adabashi long enough for Mikado to light him on fire. Masaomi is shocked at the level of cruelty that Mikado had shown and is disturbed at how Mikado can simply smile through it all. He yells at Mikado for what he was doing but Mikado simply brushes him off and walks away.
Masaomi eventually runs into Anri as well and the two of them have a rather cheerful reunion but both are worried at Mikado's recent behavior. Masaomi eventually decides to reform the yellow scarves with the sole purpose of bringing Mikado back to his senses as well as to crush the Blue Square remnants that have assimilated into the Dollars.
Dragon Zombie ArcEdit
Masaomi continues to frequent the chatroom and greets several of the new members that have joined (including Saki who joined at his invitation). He tries to get in contact with Mikado via private chat but Mikado simply replies that he'll be leaving the chatroom and logs off. Later, he enters Russia sushi with a yellow scarf around his neck and asks Kadota for advice.
Kadota's Coma ArcEdit
Continuing from the last arc with Masaomi being in Russia Sushi with Kyouhei, Saburo and Walker. Masaomi asks them to quit the Dollars and join the Yellow Scarves. Kyouhei tells him that he will think about his request, however if they ever became enemies he wouldn't hesitate to fight. Masaomi simply tells him, if that was ever the case, he'd avoid bumping into him at all costs.
When Kyouhei is hit by a car in a hit and run, Masaomi is shocked by the news. He later gathers the most loyal Yellow Scarves members in karaoke bar and plans on starting a war with the Blue Squares again in order to save Mikado. Though the other members did not like the idea, Masaomi had made his mind up. Out of nowhere, Walker enters the room with another member of the Yellow Scarves, Yatabe. Masaomi then asks Walker why he was there and Walker asks if the Yellow Scarves were behind the hit and run with Kyouhei.
Masaomi senses that Walker had suspected them, with Walker reiterating that he just wants to know if they did or did not. He knew Masaomi would never harm Kadota, but suggested it may have been a member of the Yellow Scarves working behind Masaomi's back. Masaomi tells him, if that were the case, he'd allow Walker for any punishment on his group and Walker leaves. Masaomi then notions to his members the scent of kerosene in the room, alerting everyone had they not been careful with their words, Walker would have set the room alight. Walker re-enters the room, frightening everyone, only to tell Masaomi that Shizuo had been arrested. After the night of the raid Masaomi is worried about the members that could've been attacked by Hoji (A Blue Square member). It was then he decided that he'll do anything in order to turn Mikado back, even if it meant hurting him.
