One night.
When Takumi Kusumori, a young adult young man, is relaxing at home, sudden luminescence attacks him.
And when the light ceased, there was a dark elf there.
... Dark Elf!?
"I do not know, I, mother!"
"Er, yeah yeah!"
A mother who died of a traffic accident was dark elf incarnated to a different world, and returned.
Takumi who was embarrassed at the beginning.
Every day as if to redo the lost child age.
It was coming to be horny as well ... ....
"I have been far apart ... as much as you want, you can spare your mother ...?"
