"Please give me a day off..." Tsukuru Souma, the only Dungeon seeker in the remote countryside of Mifune-cho, was forced into harsh One-ope labor due to a severe shortage of staff in the Guild. In his private life, he is a troublesome "Backseat Gamer" who sends earnest advice via expensive Super Chats to his favorite streamer, but his true identity was a real A-Rank seeker reigning in the top 0.1% of the country! This is a Story of a Shachiku boy who, despite his base of activities being in the countryside and having a lackluster appearance, spreads his name throughout the world.
