Male. He is 12 years old and appears kind and innocent. However, he suffers from depression and will immediately cut apart anything he dislikes with a chainsaw. His past: He is actually "Sumoni," a persona of "Yoni," who was the feminine persona of a Japanese man named Hitoru. Hitoru lived for 112 years and had multiple personalities. Upon arriving in Neverland, Dr. Rory of the Pipano Factory kidnapped Yoni and extracted the persona "Sumoni," placing it into a doll—that doll is Kenji. Currently, he is best friends with Pitero and Nakoseogi.

Female and cheerful. When she was human, she was the feminine persona of a man named Hitoru. Originally, she also possessed the persona Sumoni, but after coming to Neverland and having Sumoni extracted by Dr. Rory, she changed from a dual personality to a normal one. She refers to herself in the first person as "Yoni-chan!"

A 10-year-old boy who has a crush on Kenji. Before coming to Neverland, he was a boy named Peter. After arriving in Neverland, he fell for Kenji. (Actually, Kenji likes Pitero too, but chose to remain friends.) He appears timid and pure, but he is surprisingly stubborn.

Nakoseogi was a boy named Kang Suhan during his time as a human. He lived in 1756 and had a girlfriend he loved, but she was forced into an arranged marriage due to family circumstances. After she died, people wrongly blamed Suhan's parents for her death, leading to his parents being taken to the government office and executed. Falling into deep despair after losing his parents, Suhan took his own life and arrived in Neverland. In Neverland, he became a being called Rory and attempted to use Sumoni, whom he created at the Pipano Factory, as a tool to destroy the world. However, an electrical accident occurred while brainwashing Sumoni, causing Rory to lose his memories. Having forgotten his past, Rory became the current Nakoseogi. However, the past memories and traumas he thought were gone manifested as a being called Konaseogi, who constantly appears before Nakoseogi to remind him of his forgotten past.

Female, but sometimes male. She constantly appears in Nakoseogi's dreams. This is because Konaseogi was Nakoseogi's girlfriend, "Naseogi," in their past life. She always appears in Nakoseogi's dreams to torment him.

Oyashi is a copy created by a being named Kitty and inhabits the bodies of other beings in Neverland. When he enters a body, that being can only speak Japanese and becomes very quiet. (Hikito Paperly is an exception, as he only speaks Japanese because he was Japanese in his past life.)

Cheerful and has no memory of her past life. She is lively and pure. Her eyes are drawn on. She has a love-hate relationship with Kenny. She is 14 years old and frequently bickers with Kenny. Judging by her speech patterns, she is suspected to be a Japanese middle school student...!

Short-tempered and a tsundere. He is a copy created by Kitty and was originally normal, but became a multiple personality after Oyashi entered him. He also has a persona named Oliver (Oliver is a psycho, but he doesn't kill anyone; he only teases them). He appears to be 15 years old.

Male and sinister. He was Japanese in his past life. Since his death, he lives in Paperland and is a mischievous provocateur.
