Yuuya Tenjou has been bullied all his life. Then he discovers a door to another world. Powerful weapons. Vicious monsters. It all seems like a fantasy game! And when he returns to his world, he realizes that his leveling up comes with him.

Yuuya realizes that he doesn’t have many clothes that fit his new, leveled-up height. So, he heads to the mall where, in an unexpected turn of events, he ends up participating in a fashion photoshoot opposite a super popular female model?!

Yuya responds to Princess Lexia's marriage proposal and receives an invitation to an audience at the royal palace. At the same time, he returned to the Ôsei Academy.

Lexia is determined to make the most of Yuuya's visit to the capital in spite of everything that's happened. When Luna and Lexia take Yuuya out of the castle to show him around town, the signboard of a certain guild catches his eye.
