About: Lewis has a glorious past as a Hero Recruiter. It's actually with one of them he adopted his little family and taught them how to travel between worlds. One day, the latter disappeared from the Haremverse without a trace and he found himself raising his sons on his own. He now lives alone in the countryside and the solitude bothers him. That's why he never misses an occasion to invite Bunny and our Hero.
Bunny's Dad celebrating the Lunar New Year in rather kinky way. Being released at the Year of the Rabbit, his poses has a lot references to the said animal. Also fittingly because the bunny is like a symbol in his family.
