【Disused honey lamp】Deep Sea Library

A sheep girl, Tsukune, finds a suspicious black book on her journey.
It was a very rare and mysterious book. Then a boy walks by.
He seems to know something about this book.
Tsukune tries to get some information out of him.
The boy who calls himself Kotogi tells a strange story.

This story is a bit related to the [The Witch of the Golden Lamp] and [Othello na Futari] series that I published before.
This page includes the world view and character settings.
