Mai was one of the first female friends of Emi Sendo. She attends Miyaji Academy with Emi and is also interested (in a varying degree) in Vanguard. She seemingly has a shy yet sweet personality and is usually seen dressed in either her Miyaji Academy uniform or her usual attire of a yellow dress shirt and pink skirt. She was one of the first seen using the new Neo Nectar clan in her main deck in Episode 51: Golden Glow. It has yet to be seen whether she will continue to fight on with Emi or fade into the background.
