- (AR) Hentai game included AR scenario - before/after (see pg 100.)

- As for the sequel, (it has some age forms), with a strong focus on Isuta's bust going from flat to 118cm L-cup during transformation scene. She also looks more physically developed elsewhere, most notably her horns. The protagonist made a comment about changing back into a lolikko toward the end. He force-fed his little sister into transforming into a less dominating personality.
