Anime Work of Shinpei Nagai, the Director Criticized in ONE PUNCH MAN Season 3

Kapanlagi.com - Shinpei Nagai, an anime director known for his unique directing style, is now in the spotlight after being appointed to direct One-Punch Man Season 3. This appointment has sparked various reactions from fans, especially regarding the animation quality produced by J.C. Staff.

Nagai admits that he is a 'relatively unknown' figure and does not have notable achievements as an animator. He even asked J.C. Staff to keep his involvement in this project a secret to avoid creating a negative impression.

The controversy intensified after the airing of the early episodes of One-Punch Man Season 3 in October 2025, where many fans criticized the animation quality, which was deemed not comparable to the previous season.

Previously, Shinpei had also often directed several anime titles. Curious about what they are? Here’s the list..

1. Inugami-san to Nekoyama-san

Synopsis: In this short anime, we are taken into the daily lives of two high school girls with contrasting characters: Yachiyo Inugami, who has a dog-like personality but loves cats, and Suzu Nekoyama, who is cat-like but loves dogs. The two are brought together and... yes, like dogs and cats in a funny and sweet way. Light humor, short scenes, perfect for refreshing.

Release date & number of episodes: Aired from April 11, 2014, to June 27, 2014, with a total of 12 episodes plus an OVA.
