About to lose consciousness, he thought about the things he still wanted to do. That was when he heard a voice: 『The wish to be summoned has been confirmed. Granting Unique Skill 《Jack of all Trades, Master of None》』. As his consciousness faded, when he awoke he found himself on a green foggy hill, in an unknown land.
