Aru-Akise

Aru Akise ( 秋瀬 或 )
A classmate in Yukiteru's school, Aru dreams of one day becoming the world's greatest detective. The student detective was able to correctly deduce the culprit behind the serial dog murders before even the police. With his quick wits and superior deduction abilities, it's easy for others to mistake him for being a future diary holder. And his physical prowess is nothing to scoff at either, where he was able to overcome a psychotic Yuno at one point.

In Mirai Nikki: Paradox, Aru becomes the main character, the first diary holder taken in place of Yukiteru, who suffered serious injuries. Partnered up with Murumuru, she doesn't know if she can trust him or not. Although he states that he isn't gay several times, he claims to be 'in love' with Yukiteru, and wants him to become God.
