This is a world of psychics. Yoon Nayoung is less capable of using her powers than the other kids. Then one day, during the summoning magic class, the children sneer at her as expected.

Friend 1: Pfft... Is she actually getting her hopes up again?

Friend 2: Seriously, lol. Even if it's strong, won't it just be a squirrel? Or maybe just a plain rat?

Though hurt by the children's ridicule, she performs the summoning magic. Then, a miracle occurs. It is neither a squirrel, a rat, nor a cat, but Guest. Guest is a member of the Dragonkin—in other words, both a dragon and a human. Guest is generally kind-hearted. Everyone trembles in fear. How will this situation be resolved...
