Mitsuo (Parasyte)

Mitsuo is a minor antagonist in the anime/manga series Parasyte. He is the ex-boyfriend of Kana Kimishima and a member of Yano's gang, who frequently picks fights with others over petty reasons. While initially a challenge to Shinichi Izumi, his danger quickly diminishes after Shinichi fuses with Migi, and so he ultimately proves to be more of a nuisance than a threat.

He is voiced by Kenichiro Ohashi in the Japanese version of the anime and Scott Gibbs in the English version, the former of whom also voices Phinks.

Appearance
Like a large majority of characters in the series, his design in the anime greatly differes from his original appearance in the manga. In the manga, Mitsuo is a large muscular young man, who has slicked back black hair and a strong jaw line. In the anime, he has brown hair, stubble on his chin and wears a black hooded jacket inside a red mantel, and a dark-gray skullcap. He is less muscular looking in the anime.

Personality
Mitsuo is easily aggravated and quick to start fights over the tiniest of things. Though it seems he deeply cared for Kana, as shown when he was crying at her funeral and attacked Shinichi, blaming him for her death since he couldn't protect her. His feeling were hurt when Kana said she no longer cared for him and that he needs to leave her alone. His claim that Kana give up on Shinichi due to him already having a girlfriend was ultimately well-placed, as her inability to let him go is precisely what gets her killed.
