My name is Qin Sanshu, I'm 17 years old, and I live in the Sakura-sou area of ​​northeastern Chiba. I'm unmarried and once won the Merlin Award, the "Oscar" of the magic world, at the age of seventeen. I attend Sobu High School, but since graduation only requires a two-thirds attendance rate, I'm often absent and late, completely unlike a student. My main profession is detective work, and I often assist Inspector Megure of the Third Violent Crimes Investigation Division of the Tokyo Metropolitan Police Department in solving cases. Because of my identity as a high school detective, I'm very popular with girls at school, but I remain single. Because—women only slow down my deductions!

Looking at Ooka Momiji, who bore the titles of 'childhood friend' and 'adopted sister,' Mr. 55, whose body after transmigrating was now named Ooka Takeshi (originally Akai Tsutomu), felt a slight panic. "I have no memories of what happened before I entered the Ooka family. The idea of ​​having an adopted sister I could marry was just a natural progression… So, could you please remove that gun from my temple, Mary?" Mr. 55 said calmly, looking at the girl beside him who was pointing a pistol at his temple.

Shirou, who had only wanted a peaceful and easy life, was unexpectedly struck by a series of events: system awakening, blank class cards, connection to the Throne of Heroes, Servant summoning, and stepping into the Holy Grail War—thus beginning his irreversible path to becoming a nuclear-powered swordsman! The lingering scent of witches, Unlimited Blade Works, the Feast of Flames, the Fourth Progenitor, the covetousness of evil gods, the frenzied feast of god-slaying… bonds that should never have been forged begin to appear…

Inside the room, watching the two facing off, the short-haired brown girl simply played on her phone. But the temperature in the room seemed to rise higher and higher; a flash of lightning seemed to be seen between their eyes. The blonde girl with pigtails gritted her teeth, while the long-haired girl stomped her feet. Finally, they started arguing. The short-haired girl looked at them, but they seemed to ignore her and continued arguing. She put down her phone. "Stop arguing, give me, Hui, some face." A 0.0000001-second pause. The clenching of fists and the stomping of feet only grew louder. The short-haired girl had no choice but to pick up her phone again.

In the world of crossover magic, facing the unstoppable two-faced Sukuna, Lu Yang unlocks the Multiverse Projection Summoning System, listing the top characters from various anime worlds! Without even a moment's mourning for 2.5 Jou Satoru, rushing to the battlefield is—Yoriichi Tsugikuni: "Sukuna! What do you take your life for!?" Jotaro Kujo: "Sukuna's only reason for defeat is that he angered me." Gilgamesh: "The king will admit it! The king will allow it! The king will bury you, you bastard!" Water Dragon King: "I despise all those who are great… Anyway, take my breath first." Old Master: "Let's finish this quickly, don't delay my transfer of the Heavenly Master's Salvation to Bilian'er." Saitama: "Can he withstand my punch?" And then there's Uchiha Madara, Yhwach, Frilian, Yomi, Kevin, Kaname Madoka, Ainz Ooal Gown, and Zi-O… After being thoroughly beaten by everyone, the two-faced Sukuna: "...Destroy it, hurry up, I'm tired!"

What would it be like if Marvel characters gained the abilities of Kamen Rider?

Strange becomes the Wizard, and the King becomes the Beast, becoming people's last hope.

Peter Parker transforms into Electro, embarking on an adventure with four Otherworldly beings.

Phineas and Ferb, transformed into W, judge evil.

Much later, a purple sweet potato spirit arrived in a spaceship and fell into deep thought as he looked at Oma Zi-O in front of him.

"First of all, let me clarify, I'm Kanzaki Ren. Although I'm a spoiled rich kid, I really have no intention of building a harem or anything like that. I've maintained perfect, fleeting relationships with all my previous women. As for them—they were an accident, an accident..." "Is that your reason for building a harem?" "They insisted on joining, I figured, adding one is the same as adding two...right?"...

Transmigrating to various anime worlds, Shi Wushuang begins as Kamen Rider Chronos. In the realm of the God of Time, day and night are but a thought away, and time stops and flows backwards only for him.

On campus, Shi Wushuang is a gentle, cheerful, and sunny male god, but when facing strange people, he is a cold-blooded judge and a grim reaper.

The city's impurities, the Amazon lurking in the shadows, the constellation apostles on campus, the Shocker monster causing chaos, and monsters from other knight worldviews in the dimensional rift, and the BOSS.

When he is Kamen Rider Chronos, he puts his index finger to his lips and says, "Shh, during the trial, the scene must remain serious."

When he was Kamen Rider Eternal, he gave a thumbs-down sign and said, "When you get to hell, just say my name, Shinigami, and you can skip the toll."

When he is in Kamen Rider Evol Black Hole form, his right hand spins like a black hole: "This day next year will be your death anniversary, Ciao."

When he was the Blade of the God of War, he pressed his thumb down on his index finger and said, "Don't misunderstand, I just want to kill you all, or be killed by you all."

When he is Oma Zi-O: "If you do not bow to the king, you have already lost your true destiny. Your name is on the Reincarnation Stele. Bow with each step. If you are devout and sincere, your sins will be halved on the road to rebirth."

All sorts of weirdos: What? I'm taking on the Knight Boss one-on-one?

For a sufficient fee, you can commission "X" to do anything for you, including but not limited to killing your enemies, dealing with stalkers, assisting in the theft of artwork, protecting a certain professional gambler surnamed Gao during a gambling game, forming a team to participate in the "KOF" tournament, and so on.

Lin Zhe, a 21st-century college student, transmigrates into the body of a 6-year-old child. He wakes up in a room decorated with images of Action Kamen, confirming his presence in the world through the Nohara family's house number and the streetscape of Kasukabe. Shocked and bewildered by his childlike reflection in the mirror, he simultaneously receives the original owner's memories, learning that he is a transfer student at Futaba Kindergarten, thus beginning his new life in Kasukabe. ...
