ガチャ勇者のストーリークエスト!!〜勇者のスキルとして与えられた『ガチャ』の確率がシブ過ぎるんですけど、何とかなりませんかね？〜

Gamon Chiba, a salaryman in his second year of work. One day, while Gamon was slacking off from work and pulling a gacha on a smartphone app on the company rooftop, he was suddenly summoned to a castle in another world as a "Hero." Furthermore, the ability given to Gamon was not a sword or magic skill, but "Gacha Meister," a power where pulling a gacha grants him random items. He immediately used "Gacha Meister" in front of the Emperor, but what came out were snacks and sneakers. Due to the incredibly poor results, Gamon incurred the Emperor's wrath and was about to be executed, but he was saved by Marquis Colorzka and ended up going on a journey to the neighboring country as a bodyguard for his only son, Tim. However, it seems that the Marquis's only son, Tim, has a certain secret—— A difficult future ahead!? The other-world adventure of an "all-up-to-luck" hero begins here!!
