Inherent skill “”Nakadashi levelling””
It is a sexual technique that allows you to acquire experience points according to the amount of semen.

The hero with unique skills is the only ♂ summoned from another world.
To fulfill the wishes of the people of this world
In order to “”Nakadashi levelling””, I ejaculated into the vagina of a ♀ in this world.
The hero is ready. In a few more days, the day will come when the enemy will resurrect.
The unexpected happened! The enemy has made the people of this world Level 1!
People were very sad.
However! “”Nakadashi levelling”” exists! ! ! There is hope!
