We just need some excuse for Riku and Futa girl to be acquaintances. I was thinking of having Riku live in some large house initially, but maybe it might be more fun to go with what Lunar suggested and have him be in a penthouse apartment in the same tower where Terra and Jun live to increase likelihood of mingling?<br/><br/>Maybe every human PC should be in a support group for human monster families to deal with the psychological trauma, and they have some regular meet ups (possibly with monsters present, or maybe the monsters wait outside or in some designated waiting space).
