One day, a hero summoning was conducted, but only the protagonist was reincarnated.
With a changed appearance, he introduced himself as Toi and decided to live freely in another world.
Reincarnated as Toi he happened to purchase a slave named Annelise, who had been left unsold. He had intended to buy Annelise and witness her final moments, but her true form turned out to be an unbelievably beautiful girl.
In that world, there were dungeons, and Toi explored them alongside Annelise. As he received advice from Annelise senpai on dungeon exploration, Toi gradually grew, eventually reaching the pinnacle of humanity.
The abilities Toi gained from his reincarnation allowed him to freely view his stats, change his abilities and jobs, and possess a unique skill for detailed appraisal and an item box. With these abilities, which were not exactly overpowered but still quite useful, Toi embarked on his journey of growth.
