A Japanese voice actor for Zenin Maki in Jujutsu Kaisen anime is Komatsu Mikako, who played Maam in Dragon Quest: The Adventure of Dai (2020 version) and Susamaru (a demon with colorful balls) in Demon Slayer. She’s now performing Setsuna in Yashahime: Princess Half-Demon.
Here’s the video of Zenin Maki played by Komatsu Mikako!
What other anime characters has she played?
Komatsu frequently performs boyish girls. Here’s one more video in which she plays up to 33 anime characters. I’m sure you’ve heard of her voice before Jujutsu Kaisen started!
Her first name Mikako was named after Kotani Mikako who achieved a bronze medal at the Seoul Olympics. The sound is the same, but the kanji letter for MI is different. Kotani’s MI means fruit, and Komatsu’s MI means future and unknown.
She entered the entertainment world inspired by Kuraki Mai, a Japanese singer-songwriter. After a few years of activities as a talent, she’s started her career as a voice actor in 2020.
Here’s the video of Kuraki Mai songs. You may know some of these songs because she’s provided many theme songs for Case Closed (Detective Conan) anime.
