Zenitsu has short blond hair which was originally black, and brown eyes with thick eyebrows. He wears the standard Demon hunter uniform with a yellow Haori with a white triangle pattern on top.


Zenitsu is a coward and is constantly claiming he doesn't have long to live due to the dangerous job of being a Demon Hunter. He is also a bit of a womanizer and likes to hit on girls who he thinks are cute and ask them to marry him much to their annoyance.

Zenitsu has low self-esteem but still wanted to live up to the expectations others set up for him, but was constantly afraid and would always cry and run away. He claims he wants to live a modest life where he can be useful to someone.

Abilities and PowersEdit

Natural Abilities Edit

Enhanced Sense of Hearing: Zenitsu has a heightened sense of hearing, allowing him to detect danger from even the faintest of sounds.

Unconscious Combat: Zenitsu becomes stronger when he sleeps. When his life is in danger, the fear he experiences exceeds his own limits making him fall unconscious. When Zenitsu is asleep he is able to perform his swordsmanship at a high level purely based on instinct alone.

Swordsmanship Edit

'''Breath of Thunder Style''' ( (かみなり) () (きゅう) Kaminari no kokyū?)[1]: Taught to Zenitsu by a former Pillar, Shihan. This technique increases the user's strength and agility to equal a demon's. There are a total of six styles that can be used with the Breath of Thunder, but Zenitsu was so untalented that he was only able to learn the first of the six styles, which is said to be the simplest.

  1. First Style: Thunder Clap Flash ( (いち) (かた) (へき) (れき) (いっ) (せん) Ichi no kata: Hekireki?)[2] - The user dashes forward and slashes at their opponent with incredible speed. Zenitsu has honed this ability to the extent of being able repeat the dash multiple times in quick succession. He usually goes for Six Fold ( (ろく) (れん) Roku ren?)[3] (six dashes), but has been able to dash eight times within one use of the technique.
    • God Speed - Zenitsu is able to utilize this technique to further augment the speed of his Thunder Clap Flash. He is only able to use this ability twice a day. After the second time his legs become useless.


我妻 (あがつま) is one of the popular Japanese family names, and literally means my wife. There are many readings for this family name, such as Azuma, Wazuma, Wagatsuma, and one of them can be read as "Gasai", such as the name of Gasai Yuno from the manga Mirai Nikki.

善逸 (ぜんいつ) can mean goodness.

In a twitcasting broadcast segment for Kimetsu no Yaiba, Gotouge said that his name was pronounced as [Zenitsu→] with a more dragged out "suu" syllable instead of a strong emphasis on "zen" [Zen↑itsu].

Zenitsu's hair was originally black, but when he hid up in a tree during training, lightning struck him and his hair turned blond.
