Reimi Jahana♀

Head of the Jahana Group, the organization which supervises the V.G. tournaments. Reimi is wealthy, highly intelligent, and extremely beautiful. She is also a skilled martial artist and a three-time V.G. champion. Reimi initially sees the competitions as a chance to prove herself the strongest and most beautiful warrior of all, and takes a kind of perverse pleasure in watching those who lose against her be humiliated in various ways. After being defeated by Yuka, she reforms and re-enters the tournament with the hopes of regaining her title.
