Asuka Touya (35 years old) was playing an MMO as usual after finishing work when he was suddenly summoned to another world as his game character. However, the job he was given was a Priest, whose role is to store the main character's unnecessary items. Disappointed, the princesses decided to summon a new hero, a beautiful youth with the title of 'Hero'. Touya, who was supposed to be sent back to his original world, ended up being transported to an unknown place. Realizing that he can use the dimensional storage from the game, he decides to use the items inside to survive. Despite aiming to become a Berserker, the strongest warrior class he used to play, he ends up becoming a Sage, the strongest magic class. Now, he must navigate this new world with his overpowered items and abilities.
