Possessing the powers of Amon from Lord of Mysteries, a mysterious being who adopts Amon's identity, a true god with errors and dual sequences, wearing a monocle, I am a con artist who travels through countless worlds. In Soubu High School, I made the entire school do calisthenics with me; in Fuyuki City, the Holy Grail War turned into a prank war; in Marineford, I turned the Marineford War into a massive rave.

Don't ask me why, the answer is simply—it's for fun.

This is a story about chaos, laughter, and a touch of tenderness. Of course, it's mostly chaos.

Friendly reminder: Don't be afraid, please hug your blanket tightly before reading, after all, I won't suddenly appear beside you.

To save Yukinoshita Yukino, Koyama Yosuke dedicated himself to creating dreams for her and for himself. "My fiftieth golden wedding anniversary with Yukinoshita Yukino!" "My survival in the apocalypse with Kasumigaoka Utaha!" "I'm Shiina Mashiro's nanny!" Luckily, the system told him that the girls wouldn't remember what he did in their dreams and that it wouldn't affect reality, so Koyama Yosuke believed it. But the system didn't tell him that his experiences with these girls were being recorded and posted online! Now Yukinoshita Yukino, to whom I've been married for fifty years, is blocking the front door. Kasumigaoka Utaha, who shared my life and death in the apocalypse, is blocking the back path. And beside me, a classmate, Shiina Mashiro, insists on proclaiming me her father. And yet, the damn system keeps posting these videos online... What should I do?

"Mr. Xia Yu, as one of the most famous light novel writers, cartoonists, and anime producers, what do you think a good work should be?"

“The work must be able to convey the emotions of the work itself to the audience, allowing them to be moved while watching it and achieve a healing effect on their body and mind.”

"Which one are you talking about that causes depression?"

"It's the healing part." Xia Yu said as he recalled his previous works "Puella Magi Madoka Magica", "JoJo's Bizarre Adventure", "Fate"...

Well! The main theme is a loyal hero! The main theme is an entire family being executed! It's especially healing!

(Including lovelive, K-ON!, One Rock, Oreimo, and Passerby. Characters from other anime will also appear. Because of the author's reasons, K-ON! and One Rock should be the most)

In an accident, Akizuki Luoren captured his childhood sweetheart. Just two months later, he couldn't stop trembling even after eating goji berries. In times of crisis, a pay-to-win system unlocks, granting unlimited stamina. "I once wanted to be ordinary, but my girlfriend wouldn't allow it. I must possess an extraordinary body..." Thus, light novels like "KonoSuba: God's Blessing on This Wonderful World" and "Welcome to the Classroom of the Elite" emerged. However, the system's power has only just begun to emerge... The currently confirmed heroines are: Shirayuki Amawa, Ningko Fujinomiya, Saeko Busujima, and Ai Haibara.

Lin Yi travels across Tokyo, Japan, and joins a girl band training system. The more he loses, the more he earns! But the band members can only be girls recognized by the system! Although it’s a little troublesome, it doesn’t matter. Making money is hard, but how can losing money be harder? I, Lin Yi, am tone-deaf, know nothing about music, and have no management experience. Losing money must be easy for me. Let me see which beautiful girls have passed the system’s certification. Chihaya Aine, a newcomer with no basic skills, loves to show off and likes to escape, what a talent! Shiina Tatsuki, a double-standard pressure monster, a team cancer, what a talent! Kaname Lenai, free-spirited, matcha parfait, what a talent! Goto Doku, the ultimate i-person, a socially anxious person, unable to perform live, what a talent! Yamada Ryo, a person with a strong personality, a big spender, what a talent! I Serina Jina, an extremely self-centered person, a monster of truth, what a talent! ...Years later, looking at the ever-increasing figures in the firm's account, Lin Yi fell to the ground, tightly grasping Toyokawa Shoko's trouser legs: "Please stop earning!" "You're such a person, your mind is always on yourself." "If you don't have money, we can support you~" Toyokawa Shoko and the girls behind her said so. Perhaps this is the correct way to use the system...
