Ganta and Yamakatsu want ice cream from the "Hayashinaga" ice cream stand. They resort to asking Mimi for money to purchase the ice cream as they were broke at the time. In 2023, a year before the start of the series, Mimi and her classmates went to a waterpark for a school trip.

Mimi had long, smooth, black hair and grey eyes. Her bangs hung just above her eyebrows. She was seen wearing her school's female uniform which consisted of a white shirt with a red ribbon tied in a shoelace knot as well as a short black skirt.

Prison Arc
Mimi is first seen greeting Ganta Igarashi in class. She asks him what he's watching on his cell phone to which he says that their class trip to Deadman Wonderland is kind of dumb. She continues to discuss their upcoming trip with Ganta and Yamakatsu. Whilst discussing their trip, Ganta's past and the Great Tokyo Earthquake, the students see a crimson man floating outside their class window. The crimson man then smashes through the walls of the classroom and slaughters every student besides Ganta. The crimson man is seen holding Mimi's severed head in his hand.
