I Got a CHEAT SKILL in ANOTHER WORLD and Became UNRIVALED in the REAL WORLD, Too

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.

When Yuuya reunites with the girl he saved back at the convenience store, she invites him to attend the prestigious Ousei Academy. Yuuya isn’t sure that he’s worthy of attending a school full of geniuses, but he’s persuaded to try it for just one day.

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?!

Yuuya has been reunited with the first person he met in the other world, a young woman named Lexia who is full of surprises. Back in his original world, Yuuya begins attending Ousei Academy, but his life doesn’t stay quiet for long.

As Yuuya tries to find a way to level up in the Darkest Regions, he comes across a Black Fenrir pup. Yuuya Tames him, names him Night, and brings him home to live together as family. Side by side, they explore the Darkest Regions...and also go for walks.

Yuuya has found The Book of the Sage. As he reads it, he realizes that it’s even more amazing than it seems. Meanwhile, the class’s study trip draws near. Yuuya is at the department store with his friends to buy supplies when trouble suddenly strikes.

Yuuya runs across a girl fighting monsters in the Darkest Regions. She calls herself Luna. They begin spending their days training together, sweating side by side. Back at Ousei Academy, the off-campus study trip begins at a site deep in the mountains.

The study trip isn’t at all what Yuuya and the others had imagined. They’re faced with a series of unexpected challenges. Later, Yuuya meets with Lexia and her guards so they can escort him to his audience with the king, but Night begins acting strangely.

Lexia has been attacked, a crime punishable by execution. But Yuuya knows the would-be assassin and he can’t help wondering what could have caused them to do such a thing. The answer is shocking...as is the arrival of a new family member for Yuuya.

Yuuya enters the Hardblack Tree Forest, the deepest part of the Darkest Regions. He is then attacked by an unfamiliar and ferocious monster, and is in a desperate situation! A cute rabbit from somewhere... saves Yuuya's life with a voice that says, "Let me help you". Meanwhile, in the real world of Ousei Academy, a heated ball game tournament has begun!

With the regular examinations of Ousei Academy approaching, Kaori suggests that the two of them study for the test together at Yuuya's house. There, by chance, Kaori finds a "door to another world”. Yuuya is determined and invites Kaori to another world... At the same time, in the Kingdom of Arcelia, a heinous conspiracy is swirling around Lexia and the rest of the royal family!

It was Lexia's brother, Prince Reigar, who plotted to assassinate the king. While the royal castle is in turmoil, Yuuya is taken by Lexia and Luna to look around the royal capital and stop by the Adventurer's Guild, and he registers as an adventurer! Then, Prince Reigar's whereabouts are finally discovered.

Prince Reigar is caught as the mastermind of the assassination of the king and princess. What is seen is a complicated situation between King Arnold, Lexia, and Prince Reigar. The story then takes an unexpected turn when Yuuya suggests something... Then, a mysterious girl with overwhelming strength suddenly attacks.
