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?

"I hate otaku the most! What is Yosuga no Sora? Onii-chan!" Kousaka Kirino. "You need a powerful stain remover. A bed in the German orthopedic ward is ready." Kasumigaoka Utaha. "It's not me who's wrong, it's the world." Su Jie. Having transmigrated to the world of anime and manga, in order to continue his otaku life, he has no choice but to create his own ACG empire.

“Mm-hmm, Yuka, is there something you wanted to talk about?”

“……”

“Eh? I can't hear anything from your side.”

“……”

“Oh… I was just eating some freshly made oden and accidentally burned my mouth, so I couldn't help but blow on it~”

"Mr. Hachiman, you're not even 20 yet, but you've already published so many mystery novels, each of which sells over a million copies. You're hailed as a once-in-a-century mystery novel genius. Where does this endless supply of ideas come from?" "I don't think I'm a genius. I simply write by using the time others would spend partying or dating," Hikigaya Hachiman replied. "But Mr. Hachiman, there are always rumors that you're always surrounded by girls." "Well, those aren't really rumors, but I don't think they affect my writing." A new author and new book, please give me your feedback.

"System, can you let me travel back in time?"

"No."

"What about letting me change back to my original appearance?"

"No."

"You can't do this or that, but you can at least help me find a girlfriend, right?"

"No, this system cannot help you find a girlfriend, but it can make you someone else's girlfriend."

"???"

In the world of "The Irregular at Magic High School," I was bound to a villain simulator.

[Mission 1: Publicly humiliate Shiba Tatsuya, instilling murderous intent in Shiba Miyuki towards you. Reward: S-rank magic - Gravity Collapse!]

[Mission Two: Eliminate Mayumi Nanakusa during the Nine Schools Battle. Reward: God-tier CAD - Eternal Heart!]

As a result, I became a scoundrel, a villain, and a demon in everyone's eyes!

But they didn't know that when Yokohama was engulfed in flames, I transformed into "Nameless," suppressing the entire scene with a single Gravity Collapse attack. When the Great Asia Alliance invaded, I transformed into "Phantom," protecting all of Japan with my Eternal Heart.

The female protagonists, while gritting their teeth and vowing to kill me, are also searching the world for their savior, hoping to repay him with their bodies.

Until that day, my vest accidentally fell off.

Looking at the petrified female protagonists, I shrugged: "Surprised? That's right, the Demon King you hate the most and the hero you love the most are both me."

Hiratsuka Shizuka: "I say, Gokawa, you don't have any friends, do you?" Gokawa Shidou: "But I have a lot of Pokémon!" Kasumigaoka Utaha: "Shidou-kun, go on a date with me!" Gokawa Shidou: "Sorry! I have a girlfriend, there's no place for you, senior..." Eriri: "I heard you're writing a novel, it's not impossible for me to help you draw illustrations..." Gokawa Shidou: "No need! Nia can do it for me!" Yukinoshita Yukino: "Aren't cats cute!" Gokawa Shidou: "I prefer *, especially origami-like ones." Nakano Satsuki: "I... I'm a big eater!" Gokawa Shidou: "How about competing with Tohka?"

Kageyo Makoto is admitted to the Advanced Educational Academy due to her unique experiences. She enrolls as a student in Class D and discovers something strange about the school. She begins to investigate and learn about its merit-based system. (The protagonist is unaware of the actual training scenario and must uncover it herself.) She doesn't fawn over Ayanokouji.

"Hello, have you ever been in a relationship?"

"Of course not." Tenkuji You shook his head, "I really have never had a girlfriend. If you don't believe me, ask my system. If anyone has the memory of being my girlfriend, I will lose, okay?"

"Then who are they..."

Tenkuji You turned around and saw Yukinoshita Haruno, Yuuki Asuna, Natsukawa Mansu, Yukinoshita Yukino, and Kasumigaoka Utaha walking over, with an expression on their faces that they wanted to settle accounts with him.

"Xiao Youyou, I remember that you left me in the hotel without permission."

"You-kun, I said - I will not forget, I will definitely think of you, and I will never forgive you!"

"Ayou, lovers will be punished by the three pages of Ora... Are you ready?"

"Tenkuji-kun, before you break up, you and I are still boyfriend and girlfriend."

"The heroine loses her memory, the hero leaves... I don't like this old-fashioned stomach-ache plot, Youyou-kun."

"... Something is wrong with you."

Tenkuji You looked calm, but was panicked inside, and was ready to run away.

"System, come out and explain yourself!"

"Meow."

After receiving the "Another World Help Guide," Chen Lin traveled to the second dimension. He initially thought the "Another World" was a world completely different from the surface world, plagued by demons and monsters. But when he discovered the people seeking help included an elf princess and her protective knight, a snow woman who couldn't pay her rent, three succubus sisters who wouldn't let anyone touch them, a mermaid singing idol group, and a ghost's childhood sweetheart, he was shocked to realize what this "Another World" was like!?
