Kobayashi

Kobayashi is the cutest, kindest and most caring of all the dolls! He is the smallest of the 4 dolls, but an upstart. He also often jokes and cheers up, although if you lose you will simply die. He has sensitive skin, so he tries not to touch anything. He also jokes that he and Daigoro are dating, but Daigoro is very serious and rude, so Daigoro denies. All 3 dolls are Kobayashi, Daigoro and Souko

About 15 years She is a bit moody and childlike and tends to cry easily when something happens, so she is often protected by Daigoro (but she doesn't like Kobayashi very much).

Kobayashi (こばやし) is the name of one of the Kokeshi dolls that comes to Shun's room. He is the one who kills Yu (by shooting a laser from his mouth at Yu). He is also the one who talks the most. He has a well-trained high-pitched voice. Once Shun wins the game, he leaves the room with Daigoro. In the anime, this kokeshi is renamed Tarou (たろう).

he only has a doll's head and body, but if he wants, he can grow his own arms from the black mass
