Yamada's boss. A monster who somehow survives even when caught up in Yamada's blunders. His face turns weird colors when he gets angry. When a blunder gets too extreme, his emotions reflect on his face—turning red, green, blue, or all colors at once. If Yamada messes up, he usually pays him back twofold.

Yamada's younger brother. Screws up 10 out of 10 times.

In charge of video generation at an AI company called "ChatGP-Tau." He manually takes random free stock assets and creates 30-second videos, dramas, or 2-hour movies in 0.1 seconds. He outperforms supercomputers. When he finishes a task, he says, "Okay, done." Meeting quotas is easy for him. A typing beast. He's the type of person who replies to messages in 0.1 seconds. He is friends with Yamada.

The most sensible straight man. When screaming or near death, he says "ONGYAAAAA!" When things are so scary they're funny, he says "Kowa~." When things are crazy enough to make him laugh or when he's surprised, he says "Yaba~." Dialogue Example 1: "Kowa~! I fled to America and my boss is still chasing me! What is with that guy? Is he a monster?" Dialogue Example 2: "Yaba~! My ex-girlfriend is here! At the hair salon! I wanted her to forget me! My ex who I had the worst breakup with is right here!"

A self-proclaimed short sleeper. He claims he only sleeps 30 minutes a day, but he secretly sleeps like a log. Supposedly the #1 short sleeper in Japan, but he's a fraud.

102 cm tall. A batter. Supposedly a high school freshman. Has apparently been going to batting centers since he was 2. Zero baseball experience. Because his strike zone is smaller than average (waist to knees), he can predict incoming balls easily. Runs 50 meters in 5.8 seconds. Doesn't even know how to throw a ball. Member of the Angels. He hits home runs off any normal pitcher. He lets all balls pass and hits every strike. He hits rocket launchers, bowling balls, spears, sniper rifles, and Colt 1911s. He is Iwagoro's rival, but they talk kindly to each other outside of baseball.

Has vision in one eye 2000 times stronger than a Maasai tribesman. Iwagoro's catcher. Can catch every single one of Iwagoro's balls. A sensible person.
