"A lively photographer. Newbie reporter for a paper. Talks a lot, and very excitedly at that." - Arumu's In-Game Profile
She is listed as female and 19 years old.
She has lighter green hair that is worn in a ponytail and sky blue eyes. A black ribbon with an orange tag is used to tie up her hair, and she wears a similarly orange hat with a screw pattern on her head. She always has a camera slung across her in order to be able to take pictures quickly.
She is quite excitable and reckless, tending to do things on a whim and not showing much fear despite the gravity of the situation as she helps Misane and Nanase. She tends to snap pictures first and ask questions later, which she blames on being a reporter.
Arumu's boss. During her introduction, she mentions "big-boss Oui", indicating that she works for Yuuto.
