Hachimari no Machi no Sodateya-san: Tsuihou Sareta Bannou Ikusei-shi wa Ponkotsu Boukensha wo Kakusei Sasete Saikyou Slow Life wo Mezashimasu THE COMIC

Arose, a "trainer" who contributed to the hero's party's level-up with his skills but was expelled as he was no longer needed, returns to his hometown where budding adventurers gather.

He had decided to live a quiet life from then on, but then a young adventurer girl who showed no signs of growing up visits him, and before he knows it, he ends up accompanying her in her training.

An unconsciously powerful fantasy begins with a kind-hearted, all-round trainer and his friends who unknowingly become the "strongest"!
