獣耳ロリ勇者はえっちな修正に困っている

Synopsis

Isekai Revision, begin!! I, the great sorcerer Fluffy, am what's called a "World Reviser"! I'm going to resolve all of the abnormal phenomena that the furry-eared hero Miya stumbles upon with magic! …Or so I thought, but what is this immodest situation that Miya has found herself in!? The truth is, I am the cause of the abnormal phenomena. I wrote this world myself long ago in my immature novel. And so, I continue to clean up after my own mess through "Revision". It's all in an effort to better this world!
