Zenitsu Agatsuma

Zenitsu Agatsuma is a character from the manga Demon Slayer: Kimetsu no Yaiba. He is a member of the Demon Slayer Corps and part of Tanjiro's team alongside Inosuke. Zenitsu is normally a skittish and cowardly swordsman who shouts a lot, but once he hits the hay and sleepwalks, he becomes a deadly serious warrior capable of ripping through demons with blinding speed using his signature "Thunder Breathing" style. Later in the story, he develops a crush towards Tanjiro's sister Nezuko.

Zenitsu's fighting style is notable for constantly using just one form - "Thunderclap and Flash" - through most of his fights, evoking a certain quote from a famous martial artist. He later invents new techniques based on this dash attack.

While Zenitsu is certainly a popular character in his own right, within the series' fandom he pales in comparison to other, more likable characters. For instance, he is disliked by some users in the r/anime subreddit because of his "annoying constant screaming".
