The trap of lewd backstabbing

Tatsuma and Kayano are childhood friends who trained and competed in swordsmanship together.
When the Lord orders them to go to a hidden village where users live in order to learn the art of demon hunting.
The story is about a young girl who is forced to train under the tutelage of a master demon hunter named Toutetsu.

-The story structure is a zapping composition of the front training (male protagonist) and the back training (heroine)!
The first time you view the front training from the man’s point of view, the feeling of cuckoldry in the back training will be amplified. You can also read the back training from the beginning for practical use!

-9 basic CGs, 263 pages of main story
