"That sword style should have been lost to history!!" — Muzan snarled in fear.

"Kamiya Seiichi… you're terrifyingly strong! Are they serious?! Gojo Satoru is the strongest in the modern era?" — Sukuna laughed hysterically.

"Rin, the Sword Saint Kamiya Seiichi is the mightiest Servant! Summon him and we shall win for sure!" — Tohsaka Tokiomi declared resolutely.

"He is the final destination of the sword in this world." — Dracule Mihawk muttered, watching Zoro step up to challenge.

"Eh?! This has to be a joke, right?!" — Kyoraku Shunsui whispered, sweat sliding down his cheek, staring silently at the two blazing Ryūjin Jakka blades.

Sword Saint. God of Cursed Techniques. Strongest Grand Servant. The Pirate Era’s Ender…

Kamiya Seiichi: "All of my strength comes from my own hard work, the system… and transmigration!"

What should I do if I travel through time and space and become a fat otaku?

Masao Tanaka was extremely desperate. He had traveled through time. It would have been fine if his name and family were strangers, and it would have been fine if he hadn't been given a handsome face.

But why did he become a typical fat otaku like someone from an anime?

Fortunately, there is a system, but why is this system called the [Degenerate System]?

······

Yukinoshita Yukino: "It's really uncomfortable to be with Tanaka Jun."

Ying Lili: "You are a guy whose head is full of pornographic garbage. Come up with a new plot for me!"

Kasumigaoka Utaha: "I never thought that the person who wrote such a sweet novel would be you, Fat Otaku."

Yotsuya Miko: "Tanaka, help me, just destroy the evil spirits and let me..."

Fujiwara Chika: "Tanaka is really cute."

Goto Ichiri: "Tanaka, best friend."

An ordinary boy traveled through time and became Qianyu Yeyou because he was very curious about the scientific magic in the anime, and the gorgeous magic began to truly bloom before his eyes.

Eh? You mean the ritual is disintegrated?

I think I know a little bit.

What? Frost and Mist Kingdom? I think I know a little bit about it...

He traveled through time and became the cousin of Nara Shikamaru of the Nara clan in Naruto. Nara Shikahaku has a deductive transformation system. He said that although his chakra attributes are not enough and he does not have a special bloodline limit, he has a family secret technique.

What? You're saying the shadow isn't that long? The blood vessels in the human body are about 100,000 kilometers long. So, it's scientific that my shadow would become thinner and longer from the Fire Nation to the Water Nation, right?

Killing from a distance? Doesn't Shadow Seam allow you to concentrate chakra and thrust to kill? What? How do you break through the Lightning Release Chakra Coat? Doesn't Shadow Slap Technique increase strength?

How do you control the tailed beasts? Isn't the most basic shadow imitation technique enough? It's common sense that shadow imitation can freeze the body, right?

How can I defend against the Tailed Beast Balls alone? Gaara can use sand to defend himself, and the Raikage can also use chakra cloaks. Isn't it reasonable that my shadow can transform into a barrier?

Don’t disbelieve me, this is really a secret technique passed down from my family.

Izumi transmigrates to a world where everyone can convert their past life memories into power in this life. He initially thought transmigrators didn't have past lives, that he was just an ordinary person in his previous existence, but suddenly he gains the powers from the anime he used to watch. First life: Kirito... How could I, Kirito-sama, possibly do gua sha? Second life: ... Third life: ...

Overnight, two moons appeared in the sky!

Spiritual energy is reviving! A secret realm has descended!

A seven-day catastrophe has occurred, and monstrous beasts have appeared in the world!

First grade, Horatio: Headmaster, look, use this scythe of mine to hook out the soul, then lock it in this lamp and roast it with the fire.

Second grader Horatio: Principal, look at this cabbage! It can increase in value infinitely and even kill the basilisk in an instant!

Third grader Horatio: Principal, do you think this soul contract could arm the Dementors into my army of Soul Reapers?

Fourth grader Horatio: Headmaster, look, this gravity magic can pull down meteorites from outer space to strengthen Durmstrang and Beauxbatons College.

Fifth grade, Horatio: Principal, you said if I projected this mark onto the moon, everyone who saw it would be brainwashed into a believer in houttuynia cordata, and the houttuynia cordata I planted in the Forbidden Forest would sell like hotcakes.

Sixth grader Horatio: Headmaster, look! The tree that grows from this seed can convert cosmic energy into magical seeds. Then all of humanity can become wizards, mastering both technology and magic. Conquering the stars will be just around the corner!

When Chen Yunhe was born, his mother died of complications during childbirth. Six years later, his father followed in his mother's footsteps and passed away.

When he was six years old, Chen Guohui died. That was also the year Chen Yunhe discovered that this world was not a simple one, because he awakened the Sharingan. Or perhaps the Sharingan was just a bonus on the panel...

Includes works such as Demon Slayer, Oregairu, Sakurasou, Boring Girlfriend, Curse Return... etc.
