The Great Yan Empire exists in a world where respect can only be earned through strength. Within this Great Yan Empire, the four great clans have always stood above the rest. Among them, a particular incident in the Lin Clan resulted in the banishment of a certain individual who went on to start his own family, in hopes of one day being recognized again by the Lin Clan, and rejoining them…

Summoning ceremonies can freely call forth even “those which lurk in the depths beyond the gods”. One boy has top-level abilities even among the cutting-edge summoners who can use those ceremonies. He is Alice (with) Rabbit aka Shiroyama Kyousuke. But this strongest boy summoner has a single fatal weakness. Certain “cursed words” spoken by girls: “Help me.”

When Kyousuke hears those words from Meinokawa Higan, a girl brought to the verge of death, he throws himself into a city where three great summoner forces clash!

”You are NOT allowed to have affair with any other men!” the king then emphasized.

”Sure”. She replied. She never has to be the one having affair with the others. Others have it with her.
