Machimaho: I Messed Up and Made the Wrong Person Into a Magical Girl! manga volume 7 features story and art by Souryu.

In the past, Mon-chan had a pretty simple goal: consume Kayo and absorb her power. But now that he has all these annoying hang-ups like “emotions” and “guilt”, he feels bad about all the awful stuff he’s done. But if he tells Nako about his true origins, will she forgive him? And even if he does turn over a new leaf, is that enough to keep Kayo from punting him into the stratosphere?
