Kemonomimi Loli Yuusha wa Ecchi na Shuusei ni Komatteiru

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! (Source: Kadokawa, translated)
