Boku no tonari ni ankoku hakaišin ga imasu.

High school student Koyuki Seri has a disposition for whipping out witty retorts... but hates people who wait for those retorts! Much to his dismay, he had caught the eye of Hanadori Kabuto, who suffers from a terrible case of delusions of grandeur and everything about him could warrant a retort. Seri swears that he will never utter a retort about Kabuto, but he just can't hold back. Not to mention, there seem to be even more strange people gathering around him... A high school boys' comedy that'll make you laugh and laugh (but can also be cute at times) is about to start! (Crunchyroll)
