Mika's best friend (Or perhaps more than a friend, as they are usually portrayed hanging out in an overally affectionate manner), billiards junior world champion and the daughter of a former luxury hotel owner who was bankrupted by a con she believes orchestrated by Shirasagi's father. This rage prompts her to challenge Tomu to billiards, a game of skill, thinking she can't lose. With Gokijima's help, Tomu wins, although he does run into a few problems along the way. After her defeat, Abidani has her sports scholarship revoked and she moves to Taiwan to study billiards. Tomu appears to feel some remorse, as he sends her a note vowing to avenge her family --- whilst swearing his father is innocent --- and sending up a bunch of balloons shaped like billiards balls, thus leading to believe she now has feelings for him too.
