A familiar, thin figure was standing at the doorway.

He wore a yellow and black square haori, and his long, deep red hair was unusually tied in a high ponytail.

He was holding a katana that he had never seen before.

That was the back view of his father, Tanjuro Kamado.

And facing Tanjuro face to face.

It was a man Tanjiro had never seen before, dressed in a black suit and wearing a small top hat.

Because Tanjiro fell in the snow, he couldn't see the expression on his father's face, who was turned away from him.

But he was able to see the other side.

—The man in the black suit, his red eyes revealing a look of horror.

That was an expression as if he had seen a ghost.

Having traveled to the Naruto world, Bai Mo joins the Akatsuki organization under the guise of being from the future, becoming the organization's sole strategist.

He started with a brilliant, unconventional strategy: sending White Zetsu to infiltrate the toilets of the five great ninja villages to collect toilet paper, thus elevating Hidan to the status of a true Shinigami and shocking the Akatsuki organization.

Xiao Nan: Is there any that aren't so sleazy?

Bai Mo: I heard that your divine origami skills can disguise yourself very well?

Xiao Nan: Mm.

Bai Mo: Disguise explosive tags as toilet paper, sell them in five major countries, and let the world feel the pain when they wipe their butts. Art is an explosion!

Payne, Deidara: ?

Bai Mo: Nisuke, if you really want power, just drink a sip of Naruto's 'milk'.

The protagonist is transported to the world of Battle Through the Heavens by a system. However, the protagonist discovers that the world the system transported him to is somewhat different. Ten thousand years ago in Battle Through the Heavens, there was actually a super...

I transmigrated into the body of an ordinary student at a Japanese elite academy and became bound to the Involution System.

Before enrolling, a scan of all the passengers on the bus revealed that Kiyotaka Ayanokoji's fighting skills were S-rank!

Kikyo Kushida's social skills are grade A, Rokusuke Koenji's aristocratic manners are grade B...

I sat quietly in the corner, but in my mind I was practicing martial arts in the virtual space.

The moment Ayanokouji looked at me, the system notification appeared: [Martial Arts (S-rank) Successfully Acquired]

He will never know that with just that one glance, I had already been "killed" a hundred times in my mental world.

Eric, who had been forced to play The Sims for ten years, opened his eyes again to find himself finally in control of his body. Before he could even get started, he was bombarded with a barrage of information that left him dizzy. "I've arrived in the magical world of Harry Potter? And the original system has self-destructed?" When the Sorting Hat was placed on his head and loudly proclaimed Azkaban, Eric knew he was destined for greatness.

As the fourth child of the Shinomiya family, I began living independently. Every day, I woke up in the dark closet, went to my bed, and took out a dummy, placing it under the bed. Then I checked the blades in the soles of my shoes to see if they were sharp, cleaned the potassium cyanide particles from my waistband, checked the prohibited words on my clothes, and made sure the miniature surveillance devices were working properly. I placed a bayonet in a book, and a submachine gun and bombs in my backpack. Completed, with a smile, I headed towards Soubu High School. As a normal high school student, I greeted a beautiful day. As a normal high school student, aren't the things I have normal?

Nangong Xiao: "I know more about this other world than anyone else." Asuna: "..." Nangong Xiao: "I'm not cheating, really, why are you looking at me like that?" Kasumi Utako: "..." Nangong Xiao: "Who says a cruel other world can't have a normal daily life?" Maple's eyes lit up: "!!" Nangong Xiao: "War is always the last resort. If you play it like a normal card, things will get very..." Shizuka: "Shut up! You're the main DPS, just focus on outputting damage!!" Nangong Xiao: "Ah, oh, coming right now..."

After being transported to another world, Mizusaki Yuuma looked at the newly released "Love Metronome" and realized it was a sweet slice-of-life romance anime. However, he encountered a girl collecting Clow Cards, a pile of scrap metal collecting the Peace Star, and a Sherlock Holmes from the Heisei era. He also occasionally heard urban legends about Tomie. Fortunately, his Yorozuya (Odd Jobs Shop) always attracted strange customers who traded things from other worlds with him. There was the Battlefield Rose from the ninja world, a rebellious girl from the world of navigation, a fox spirit from Valoran, and a girl visited by eight million warriors. Kasumigaoka Utaha: Hey, you have to take responsibility! Kinomoto Sakura: My brother is so nice, he helps me collect Clow Cards. Irelia: Grandma always says... Mizusaki Yuuma: Stop nagging Grandma, when are you going to pay back what you owe? In the corner, Mai Shiranui, remembering she still owed money, was trembling. ...
