The guide girl

In a fantasy world where spirits and monsters exist and humans can wield magic, a former high school baseball player finds himself reincarnated.

He manages to enroll in an elite academy for learning magic, but unfortunately, his grades are at the very bottom. Because of his small and distinctive stature, he earns the nickname “Goblin Count.”

Determined to prove his classmates wrong, he breaks a small school rule—and ends up becoming the servant of a supposed “spirit” who looks like a three-year-old child.

However, this three-year-old turns out to be a rule-breaking existence—banished to the mortal world for excessive mischief.

Spoiled, gluttonous, mischievous, lonely, clingy, and always wanting something—while being constantly troubled by this little child, he gradually realizes that beneath that small body lies unimaginable power and vast knowledge.

With that, the reincarnated boy Moronidas resolves to catch up to one girl—

To stand by her side once again, the boy begins to chase after the back that had grown distant—
hand in hand with the mysterious three-year-old guiding him forward…
