He was at Hogwarts, and had just become a Half-Blood Prince.

…

In 1976, 16-year-old Severus Snape welcomed a new life.

That year, Voldemort had not yet split his soul into seven pieces.

That year, Nagini was still hiding in the forests of Albania.

That year, Pandora was still doing wonderful experiments at Hogwarts.

That year, Ms. Rosmerta was in her prime and very graceful.

That year, Snape decided to experience this wonderful world.

The labyrinth city of Orario—a vast metropolis encompassing a magnificent underground labyrinth (commonly known as a "dungeon"). The thrill of the unknown, the glory of splendor, and even a romance with a lovely girl. In this city where dreams and desires lie in wait, a young boy encounters a small "god." Rejected by all the "families," the boy, determined to become an adventurer, encounters a fateful encounter with a god with zero members. This is the boy's trajectory, the goddess's record.

Travel through Naruto and activate the harem skirt. All the women who enter the skirt will be his future harem.

Every day, you can make up a future video related to the skirt members, and the video will become true.

Mu Mu: So, if you want a certain ability, just make it up? If you want a certain woman, just make it up?

then–

Konoha Shika: What? We are going to marry Mu Mu together. What is his merit? … He is the hybrid of Senju, Uzumaki and Uchiha, and he has activated the three bloodlines at the same time. He is also the sixth Hokage! That’s fine. We are willing to marry him!

Xiyan: Jifeng is a tuberculosis patient, I like people who are strong and healthy!

Xihi Kurenai: Mumu is too manly, and that cannot be decorated with a beard.

Hongdou: Marry Mumu and you’ll have endless meatballs to eat. That’s great!

Tsunade, Mei Terumi, Kurotsuchi, Samui…

As one after another entered the skirt, everyone gradually became dumbfounded.

Is this a way to capture all the beauties in the ninja world? Are his kidneys made of alloy?

Kushina, Mikoto, Nohara Rin, Uzumaki Mito, Uchiha Ji…

Unexpectedly, even the dead were not spared? !

Servant Lancer Remlia Scarlet... Queen of the Night, reigns here. From now on, I will be your master, servant, are you type B blood?"

"Servant Saber Akame, in response to our previous meeting, nice to meet again, Master."

"Archer Misaka Mikoto, eh, do we know each other? Hey, hey, hey! Master, your pick-up method is too old-fashioned."

"Servant Saber, I came here in response to the summons. Well, just call me Kirito."

"Servant Archer, my name is Tokisaki Kurumi. Ah, Koizumi-kun, we are also an accomplice who saved the world together. Why are you hiding from me like this?

Bai Chen, having just traveled through time, hadn't figured out what was happening when Siegfried usurped his throne. Expecting to bring shame upon the other traveler, Bai Chen suddenly heard a voice. "Chat invites you to join, yes or no?" "I'm dying, why are you here just now?" Huh? There's also a lottery feature? ... Tokisaki Kurumi: "I'm not allowed to post cards here. Thank you for your cooperation!" Bai Chen: "I just got this, newbie. Does it work?"

After being transported to the world of Genshin Impact, Han Feng obtained a god-level comic book store system.

My name is Kyosuke Kamijou, and I live in Genjimi Taki. I am a Stand user. My peaceful life has been gradually disrupted since I awakened my memories from before I was transported to another world.

Having acquired a system called 'Eye of Heaven,' my timid classmate, a fellow sufferer, suddenly develops a split personality one day. Upperclassmen keep finding various excuses to invite me to their homes for tea. My best friend, with whom I play games, frequently invites me to the arcade, and even my two childhood best friends start acting strangely.

Mami Tomoe: "Kyosuke, would you like to come to my house for some black tea after school?"

Hitomi Shizuki: "Kamijou-kun, could you help me with my homework?"

Kaname Madoka: "Kyosuke-kun, we made a promise..."

Kyoko Sakura: "Hey, Jojo. Let's go to the arcade today! I heard they've released some new games."

Homura Akemi: "Please, Tamura-chan!"

What? You're asking where the childhood sweetheart is?

I admire the first person who wished to become a magical girl, because maybe that was a lie?

You are the ones who escorted me to heaven, Cupid!

One last time, the path to heaven is about to be accelerated...

The savior of magical girls? I'm just a stand-in user passing by.

I awoke from a dream, incomprehensible murmurs echoing in my ears. Forgotten myself, lost my past. Looking around, I realized I was in hell—explosions raged across the azure sky, bullets ravaged the streets like a torrent, and war burned constantly across this land. The aliens who lived here possessed seemingly fragile yet fearless bodies, forming gangs for their own purposes, killing each other day and night. Then, they discovered me. They called themselves students, told me this place was called Kivotos. They also called me—Teacher.

For Chen Lingxu, the ancient Qilin overlord who descended from the heavens, once a Tikkaz, always a Tikkaz. Do you think that transforming from a bunch of aliens into the busty, slender, long-legged, and shapely Sarkaz, Sarkaz, Durin, Anassa, and Oni beauties... can sever ties with what he did as a Tikkaz? For Chen Lingxu, the Primordial Celestial Venerable who once ruled over the Shuangmin, the beastly acts of the past are irrelevant, but the abundance of beauties of today are readily available. Awakened by a green-haired lynx, Chen Lingxu looked at himself in the mirror and exclaimed in shock: "Wine and women have made me so haggard? From this day forward, I will abstain from alcohol!" He then told the lynx, "Please rest assured, AMA-10, I am also actively interrogating the alien female spy today!"
