Kadokawa

Yuuya has always been a loser, and after the death of his grandpa (the only person he had in his corner), he's sure there's no point even trying anymore. But when Yuuya moves into his late gramp's home, he inherits... a two-way door to another world?! Access to this new realm might be just the cheat Yuuya needs to succeed in his everyday life!

A chance to come back!

Á mysterious door stands open, inviting a boy who's been brutally bullied all his life to take a courageous step forward into the unknown. On the other side, he finds a hoard of priceless artifacts and a world as filled with magic as it is with monsters. The most shocking revelation, however, is that he can bring whatever he wants back with him when he returns to Earth. It won't be long before this double life changes him forever...

When the home left to Yuuya by his grandpa leads him to another world, Yuuya levels up in his own mundane reality! But despite his new otherworldly cheat, his life is still far from easy - his old bullies have an even bigger bone to pick with him while his new acquaintances from the elite Ousei Academy hold him to lofty expectations. Then, as Yuuya struggles with his new responsibilities, political schemes of the other realm threaten to throw his hard-earned peace into chaos...

Living his best life!

Leveling up has truly changed Yuuya's life. In the real world, things have done a complete 180. He's getting used to his new school and making fast friend-which includes a fluffy companion in the other world. Meanwhile, thanks to his physical prowess and good looks, his popularity is through the roof (though he's oblivious to this). He's also finally learned how to use magic! Will it be enough to help him survive fires, assassins, and trials in the wilderness?!

As Yuuya's skills in the other world improve, so too does his life in the real world. Starting fresh at Ousei Academy, he begins to shine at academics and sports, even making a few new friends. Has Yuuya finally found a place that really accepts who he is?

Life in the Limelight!

Yuuya's not sure how things ended up this way. His training buddy, Luna, made an attempt on Lexia's life, and now his planned visit to the capital has fallen apart. The King's opinion of him has hit rock bottom, and conspirators against the crown are eager to make Yuuya the scapegoat for their heinous plot. Back in his world, the Ousei Academy Ball Sports Tournament is making it impossible for Yuuya to stay incognito, no matter how much he's rather avoid the attention. His good looks and strength might be unrivaled here as well, but can he handle the pressure and responsibility that come with them?!

As Yuuya surveys the Weald, a mysterious cave suddenly opens up before him. Within the cavern, he finds the body of a legendary sage and a book containing their last words - many of which are addressed... to him? The dead sage bestows their mana pathways to Yuuya, granting him the previously unattainable ability to utilize magic! Between these newfound skills and an encounter with a mysterious girl, can Yuuya navigate this increasingly dangerous world while still making time his his classes at Ousei Academy?

A Knight in Shining... Thunderbolt Armor?!

After stopping an assassination attempt on King Arnold and Princess Lexia, Yuuya is roped into the hunt for the traitorous Prince Reigar. In the ensuing chaos, a mysterious girl attacks without warning. Her goal? Destroy the world! To have any chance of holding his own against this new foe who is on par with Master Rabbit, Yuuya will have to think fast - as fast as lightning. Hopefully, his quick thinking will be just as useful on Earth, because when Kaori visits his place to study for midterms, she accidentally stumbles upon the door to the other world!

Corrupted by the Dark Side!

After a narrowly won battle, Yuti surrenders to Master Rabbit and Yuuya, abandoning her plan to destroy humanity. She has no home to return to, so Yuuya offers up his. However, traces of demonic energy remain inside Yuti, and there's no telling when they might take over, so Yuuya decides to risk transferring them to himself. Will he be able to resist his dark impulses and the temptation of power?
