I'm a Summoner Who Can Only Summon Monster Girls

[A serious story, but with plenty of steamy scenes.]

After dying, a boy is reborn in another world.

He has an enviably huge amount of magical power, but when his talent awakens, he discovers he can learn no magic other than summoning?!

In this world, summoning is considered the weakest kind of magic.

"Then what's the point? I might as well go home and farm."

That's what the boy thinks, right before disaster strikes.

What he summons isn't a weak monster, but a powerful female knight.

"Tell me, are you my Master?"

With a familiar story unfolding, a quirky everyday comedy about life with monster girls begins.
