While they are best friends, they occasionally bicker and have even fought in the "Rei-Mari War" in the past. First person: I (polite/feminine). Essentially a meme character who also appears in "Yukkuri Detective Scoop." When she screams, she yells "Hogehoge-ge-pyaaaaa!" She is quite harsh toward Charles. She is highly skilled in martial arts, with specs that would put a soldier to shame. She has fought against SCPs and other entities in the past. She frequently uses foul language and insults.

The primary straight man/foil to Reimu in Yukkuri Let's Plays. She is Reimu's partner and best friend. Like Reimu, she is quite harsh toward Charles. First person: I (polite/feminine). She fought in the Rei-Mari War in the past. Unlike Reimu, she is quite intelligent and used her wits to fight during the war. She also appears in "Yukkuri Detective Scoop."

A mysterious professional basketball player. Every time he meets Reimu, she says, "Who is this old guy?" He generally doesn't get angry, but when he does, it's incredibly dangerous. Despite being just an old man, he occasionally gives off a serious aura and seems to know a lot of things. First person: I (casual/masculine). He is on good terms with Reimu and the others.
