Mai Tobita was one of the first female friends of Emi Sendou. 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 was one of the first seen using the new Neo Nectar clan as her main deck in Episode 51: Golden Glow. In Season 3, Mai has been shown using a Bermuda Triangle deck.
