Raijinmaru

Raijinmaru is a character in the Manga World Trigger. She's a resident in Tamakoma Branch and Yōtarō Rindō's pet capybara.

Appearance
Raijinmaru looks like a regular capybara, with a big head, a big body, and short, thin legs. Her body is covered mostly in light brown fur, with darker fur covering the tip of her snout and her limbs.

Personality
Not much is known about Raijinmaru's personality, but she seems to a very lazy and gluttonous capybara.

History
Rindō apparently bought her from nowhere. She joined Border during its debut.

Black Trigger Capture Arc
Raijinmaru appears multiple times in Tamakoma Branch, with Yōtarō trying to play with it.

Border Enlistment Arc
She is seen with Yōtarō atop her after Osamu's battle with Midorikawa. Yoneya was babysitting him for his cousin.

Yōtarō sits on top of her while watching the Rank Battles. During the Galopoula Invasion, Yōtarō rides on her to Hyuse to return Lampyris to Hyuse.

Trivia
