Description
Ruhuyu is a wolf girl Myumon known for her cheerful, healthy, and diligent demeanor, often viewed as an honors student. Her dedicated and compassionate nature fosters trust in others. Beneath this exterior, she wrestles with internal conflicts over parental expectations, leading to doubts about her predetermined future.

She possesses long lavender hair usually in a ponytail, teal eyes, caramel skin, and a matching lavender tail. Her typical attire includes a midnight blue and white outfit, black stockings, dark violet boots, and indigo paws with pink padding. She stands 157–158 cm tall and was born on December 22.

A defining personality trait involves occasional destructive impulses she struggles to control, resulting in rumors about her potential danger. She describes her personality shifting dramatically during full moons, adopting a melodramatic and impulsive demeanor where she readily jumps to conclusions. Her speech and actions frequently incorporate the "lunatic" theme, using playful phrases like "Lunatic Razzle Dazzle."

As drummer and vocalist for Mashumairesh!!, she plays drums named "Lunatic∞Overload." Her band involvement catalyzes personal growth, particularly through interactions with bandmate Delmin. Their dynamic evolves into a comedic "tsukkomi and boke" pairing, with Ruhuyu often acting as the straight-faced reactor to Delmin's antics. This bond deepens as she shares more of herself, including moments where Delmin reads her diary, reflecting growing trust.

Her development includes efforts to integrate her "lunatic" identity into the band, initially tolerated but later becoming a source of lighthearted teasing as their bonds strengthen. She expresses enthusiasm for improvement when praised, vowing to work harder. Outside the band, she enjoys diary writing and practicing "gaugau war-exercise."

Her character songs include "Last Judge" and "Cinematic Memoir," plus a duet with Delmin titled "No Problem!!." A video series, "The Road to Ruhuyu's God Drums!," was released via official channels starting November 2019. She maintains an official Twitter account.
