Akisaki Rio

Lilian Eddington finds a mysterious but cute black beast in the woods, which she refuses to abandon when her grandfather says she can't keep it as a pet. After he finally consents, she kisses the newly named Woolbo on the nose only for it to release the seal on it and it turns into the Maou. While condescending at first, the Maou decides he can't abandon Lilia either. How will their days together play out in the future?

A man who was enjoying an evening drink got transferred to the body of Liam, the fifth son of a nobleman from another world. "I spent easy days practicing the magic I had longed for, and learned not only attribute magic, but also how to summon spirits, obtain powerful familiars, and ended up mastering even the most difficult magic!" He became an adventurer aiming for independence from his parents' house, which was scheduled to fall, and before he knew it, he became a higher-ranking aristocrat rather than one of the best magicians in the world.
