Jibanyan

ジバニャン

Akamaru was the pet name given to him by his owner, Emi, while she was still alive.
As a Yo-Kai, he resorts to possessing people to fight oncoming trucks after numerous failed attempts to do so on his own. Fortunately, Nathan and Whisper stop him and befriend him, leading him to decide to move into their house. He initially displays a mischievous and carefree side, easily breaking rules and ultimately nearly being exorcised, requiring Nathan to save him. However, he quickly makes amends shortly thereafter.
Jibanyan has an affinity for chocolate bars and anything related to his favorite music group, MeowKB. Jibanyan is also eager to fight other Yo-Kai when needed, as demonstrated during Signibble's assault at Nathan's sleepover. Additionally, he is quick to take action in dire moments, such as trying to force a summoning when Nathan is possessed by Babblong and attempting to prove his superiority over Robonyan, his robotic counterpart.
