Renko: A physics major and the president of the Hifuu Club, of which you are the 3rd and current final member of. Renko is very daring, and sees things in a very objective way. Renko is basically a human GPS.
Maribel/Merry: Psychology major, very laid back and the 2nd member of the Hifuu Club. Extremely polite and rather subdued, and somewhat even ladylike. Her power is seeing and slightly manipulating "gaps" in reality. Recently went missing. 
The two are best friends.
