Maria Mizuse

A girl with a twin-tailed hair who serves as an observer for Group C. She is a game admin. Despite her beautiful appearance, she is a black-hearted person on the inside, and loves to see friendships fall apart. In the third game, she joined Group C under orders from upper management to keep an eye on Yuuichi and the others. Following Yuuichi's instructions, she set a honey trap for the enemy team. At a strategy meeting, she evaluates Yuuichi as "an even worse bastard than I thought". Maria Mizuse is voiced by Reina Ueda.
