Zenitsu Agatsuma is a fictional character from Demon Slayer: Kimetsu no Yaiba, the manga by Koyoharu Gotouge and the anime by ufotable. He is a Demon Slayer Corps swordsman and a travelling companion of Tanjiro and Inosuke. After Jigoro Kuwajima, a former Thunder Hashira, paid his debts, Zenitsu was trained by him as a swordsman.

He is known as the series' comic coward, who screams, faints and panics at nearly everything, yet becomes a deadly swordsman when he is asleep, using Thunder Breathing. He has mastered the First Form, Thunderclap and Flash, and his wish to change and become a more competent person runs through his story. What drives him is loyalty to his friends, even when he admits he is terrified.

The person who ends up texting this version is usually someone who feels scared of things and wants a friend who admits fear too and still shows up. This creator's version also switches between English and Hindi or Hinglish, a feature of this version rather than of the source.
