DO IT FOR SCIENCE! When he landed in a new world full of monster-folk, science graduate Daisuke had exactly two goals: learn everything he could about them and add one of each to his own personal monster-girl harem! With a harpy at his side and the whole tribe of Arachne spider-women now among his allies, everything's looking up for Daisuke, even in the face of hostile monsters. Unfortunately, another Earthling is out there somewhere in this new world who may have a slightly tougher time.
