The problem with the letters and the team names is partly why I thought team names unrelated to character names would be good, but NOOOOO. XD

How's this for team match-ups, any problems with them?

Isaac, Arara, Daiki, Orion
Sayuri, Morella, Grizel, Tirren
Pascale, (Unnamed Loli, prolly beginning with "N"), Addica, Kiora
Alistair, Casterly, Reya, Jaclyn
Oliver, Kalimay, Rygar, Tarkus
