Mei Mio was one of the female students that attended Akademi High School. She now appears as a background character in the town.


Mei wore the default female school uniform, unless customized by the player.

Before the February 8th, 2016 Build, Mei had blue colored hair worn in tritails, one on each side of her head and one in the back. She also had bangs in the same style as the default Ayano. Her eyes were cobalt blue as well.

Before the May 2nd, 2016 Build, she had cobalt blue hair pulled back into a ponytail with strands of hair that hang to the right, some hair around her neck that reaches her shoulders, and bangs that curl inwards to her cheeks and dark blue eyes. Her bust size is 1.4. She wears blue framed reading glasses.

Before the December 18th, 2017 Build, Mei had blue hair tied in a small bun. Her bangs were longer on her right side, and she had an ahoge on the top of her head. She had a bang going down the middle of her face and another smaller one to the right of the larger bang.

As of the January 16th, 2017 Build, Mei wore a blue friendship bracelet on her right wrist.

As of the February 2nd, 2017 Build, Mei wore blue stockings and panties.

As of the December 18th, 2017 Build, Mei had blue hair tied back into tritails on the back of her head. Her bangs were parted to the right, with a blue hair clip partially holding them back.

As of the January 13th, 2018 Build, Mei's bun was restored due to negative feedback from fans.

Mei had the Teacher's Pet persona. She would give Ayano a suspicious look if she aimed her phone at her. If she saw a corpse or witnessed a murder, she would report to her teacher, unless another Teacher's Pet already had. She couldn't participate in physical fights against murderers.

In her reference photo, she was shown to be studious, as she was seen studying at a desk.


At 7:05 AM, Mei entered the school grounds. She walked to her locker at 7:10 AM and changed from her outdoor shoes to her indoor shoes. At 7:15 AM, she walked into the plaza, to the left side of the fountain, and gossiped with Yui Rio, Yuna Hina, Koharu Hinata, Saki Miyu, and Kokona Haruka. She would also gossip with Musume Ronshaku before the bullies were implemented.

At 8:00 AM, Mei walked into Classroom 2-2 and sat at her desk. She started her morning classes at 8:30 AM, and left to go to the cafeteria to gossip at 1:00 PM after class.

Mei walked back to class again at 1:30 PM and participates in cleaning time between 3:30 PM and 4:00 PM. Afterward, she headed to the Cooking Club and stayed there until 5:00 PM. She then headed to her locker and changed from her indoor shoes to her outdoor shoes, then she lingered there until 5:15 PM when she walked home.

In Buruza Town, Mei walks around, looking at the scenery, and can be seen looking on the edge of the town, towards the ocean.
