Peach Boy Riverside Wiki

Mikoto Kibitsu (キビツミコト, Kibitsu Mikoto) is the main male protagonist of the Peach Boy Riverside series. He has come to the Western Continent to kill any and all Oni that he encounters. He travels with a dog and a Oni named Millia. He frequently runs into Sally on his journeys.

In the Manga, it is revealed that Mikoto is the son of a human woman and an Oni male named Gaki. He was entrusted to the village by Gaki after he ate his wife on accident. Though the village thought Gaki to be human, the village discovered a horn on Mikoto's head and tied him up to be publicly berated.

He apparently took his name from the original Momotaro of the Japanese folklore, who took him in and raised him. He decides to kill all ogres after Momotaro is killed by the Kishin. The original Momotaros sword and his talking dog are entrusted to him.


Mikoto is constantly thought to be weak upon first encounters. He is young boy of average height and has dark, long hair and a very soft voice, due to which he is often mistaken as being a girl. In battle against Oni, he takes on a form of bloodlust that terrifies even those that care about him.


Mikoto has a twisted personality


Mikoto journeys to the Kingdom of Aldarake. He meets the princess Saltherine Aldarake, who asks him to hide her from the guards. Learning that he is a traveler, she invites him to stay at the castle and tell her about his journeys. Mikoto finds Aldarake to be a nice place, peaceful with kind people, but Sally finds it boring. The next day, Sally is surprised to learn that Mikoto is a boy. While walking around the castle, he sees Yaki, an Oni. He goes out and finds group of Oni led by Moki. He asks Moki if he was the one that destroyed the kingdom in the north and as Moki confirms, he cuts off his arm. Mikoto then proceeds and kill all Oni and then finishes Moki. Initially Sally wanted to go with him, but seeing all the dead Oni, she stops. Mikoto then continues on his journey with Dog.

Power & Abilities[]

Mikoto Kibitsu holds a long katana in his left hand and probably uses it to swing it at enemies at a swift of his blade. He is a skilled combatant and one of the most proficient at killing in the whole series. His daring looks also show that he’s probably the type of boy who takes matters into his own hands and would rather work solo instead of working in a team. His cold demeanour however attracts more comrades as they console him that he doesn’t have to do things alone, but the bright side about him is he doesn’t take things for granted and he always sees a bright future ahead for the future of his comrades. but let’s get onto his abilities.

Peach Eyes:

Mikoto originally didn't have Peach Eyes. He got the them when Hiko (The Original Owner of Peach Eyes and the teacher of Mikoto Kibitsu) was killed by Magic/Law God Oni Nobrega. After his master death the Peach Eyes move from Hiko to Mikoto and at the same time his Oni Power awaken, and with the help of his Oni Power and the Peach Eyes he was able to kill his teachers murderer Law God Oni Nobrega. Also in the manga and animr it is seen that Mikoto has 2 peach eyes while Sally has one, but having 2 peach eyes doesn't necessarily makes him stronger than a Kishin/God Oni class beacause Hiko also has 2 Peach eyes, the most probable reason Mikoto able to kill Kishin/Oni God class is because of his oni power combine with the Peach power

Oni Power:

His Oni power awaken the same time when he received his Peach Power from Hiko. Wich makes it adapted to his peach power and from the manga his Oni Power gives him the ability to eat any attack from oni, he can even eat an attack from an Oni God/Kishin. (The part his Oni Power adapted to his Peach Power is only a theory, the reason is because the ability to eat Oni's attack is very compatible to his Peach Power).

Saltherine Aldarake

Mikoto and Sally seems to be in good relationship. They both hold each other in high regard and will do anything to help if one of them is in danger. It appears Sally may has developed romantic feelings for Mikoto , as everytime they meet Sally blushes heavily and wonders what to say, but this has yet to be confirmed.


According to Nihon Shoki, Hiko Isuseri-hiko no mikoto, son of Emperor Kōrei, took the name Kibitsu-hiko-no-mikoto (吉備津彦命) with 'Kibitsu-hiko' meaning 'powerful man of Kibi' after subjugating Kibi Province. In legends, the prince slays an oni called Ura, which may be the demonization of the Kingdom of Kibi, destroyed during the reign of Kōrei. Some suggest story of Momotaro stems from the legend of Ura thus making Okayama Prefecture, where Kibi Province was located, 'the birthplace of Momotaro'. Also, the prince is deified in Shinto shrines of Okayama and Hiroshima Prefecture.
