English :
The daily life of Kusa Kouichi, a High School Student who is not good with erotic-stuff, changes drastically during the second summer vacation as a high school.
By any chance, his childhood friend Mia is actually a FAILED SUCCU that has no experience.

He was caught up in a ridiculous situation that it would be bad if they did not do the naughty "training".

What's more, for some reason, the girls who are related to Koichi are all herbivorous succubus like Mia is.

Indonesian:
Kusaka diminta mengajari Mia, osananajiminya yang ternyata setengah Succubus dan teman-teman Succubusnya yang lain hal-hal yang berbau mesum, dah gitu aja...
