"Love Thy Enemy" is the first episode of Durarara!!x2 Ten and the fortieth episode overall of the Durarara!! anime.
In a city without its information broker, the residents of Ikebukuro spend their day off in various ways. Some go shopping with their families, others spend time with their lovers and friends, or conceal the spark of new determination in their hearts, while still others take action, spurred on by the seeds sown by the information broker… The hint of an uproar lurks beneath the surface of what seems to be, on the surface, a peaceful day. And far from it all, all day, Izaya waits. For “someone” who’s coming to kill him.
