Detective Conan? Oregairu? Saekano? Turns out I've been transported to a crossover anime world! The air is thick with hormones. Hasezawa is ready to find some fun in this boring world of romance~

And so, the zombie siege began! Will Megumi, the Saint, remain unfazed amidst it all?

Now, let's have some fun together!

Because of a certain goddess's wickedness, Takuma Tsukishiro, who arrives at Tokyo Metropolitan High School, is forced to become the villain. Only by amassing enough evil points can he survive. Well, as a villain, a bit of hypnosis makes sense at the beginning, right? Modifying common sense is perfectly normal, right? So, time-stopping is a natural, right?

[Characters appearing include characters from Honkai Impact 3rd, Star Iron, Grand Blue, Oregairu, Kaguya-sama: Love Is War, and Saekano... as well as some heroines whose origins are unclear. I won't cite their sources; those who like these series will understand.]

Don't worry, it's not some cuckolded turtle.

(Harem/Male Protagonist) (mygo+mujica+BanBan Old Group) In a basement that anyone could find, Shiranui Mio pondered why those girls who were once his closest confidantes would drug him and imprison him here. But at least, he knew what he should do now was... struggle for survival. "Hey, can we reconcile?" The girls didn't answer, only silently staring at Shiranui Mio. In a daze, he seemed to see his juniors from Haneoka mixed in with the crowd. "Even if you tie me up, what you can't do, you can't do. I'm not some omnipotent god!" As soon as he finished speaking, the girls were in chaos. After a moment, a timid voice rang out: "We just hope Mio won't run away again." Huh? What kind of reason is that? Backed into a corner, Shiranui Mio could only recall that late morning, the ancient method of opening a box from the blue-haired girl, when he closed his eyes. "Hello, are you Shiranui Mio, the former captain of SPACE?"

(Harem-oriented, please don't enter if you don't like it) I'm weak, unlucky, and inexperienced. But that doesn't mean I can't do anything. Even if it's just for a day, a moment. There will always be moments I won't want to forget. A world where everyone is happy? I'll do it, so please watch. "I'm watching you! Don't use Den-O's lines seriously to flirt with girls, okay?!" Sawamura Eriri lashed out at her shameless ex-boyfriend Hanyu Aozora with her ponytail. "You can't even handle two people..." Kato Megumi pouted lightly, "Let alone Nino and Fumino." Eriri turned back stiffly, "So there really are?" "Yes, there are many more." Furious, Eriri used Starburst Stream Slash, with remarkable effect.

"That year, I saw the students of Class B slumped in their chairs, sobbing uncontrollably. That scene is unforgettable. At that moment, I thought, if I could become the class president of Class B, I would lead Class B to victory!" "So, Ichinose, let me be the class president of Class B." "No, Uesugi-kun, you're too radical." "Ichinose, you'll regret this!" "Uesugi, I am the class president of Class B." *Slap!*... "Hmph, naive Ichinose, do you think I can't do anything if you don't agree? Shibata, notify Kanzaki to prepare to close the net!" "Uh, um, Uesugi—" "Shut up, Shibata, this time we must act quickly. Before Ichinose can react, expel them from school. I want to see who can stop me this time." After a while, "The wind on the rooftop is so strong..." "Uesugi, come down quickly, I will never reveal your plans to Ichinose again." "You write it down!!"

“Dad, if you don’t take this chance to win Mom’s heart, I’ll disappear because history will change!”

Wu Shen thought he was destined to live a lonely life…

Until one day, he wakes up to find several girls appearing in front of him—each claiming to be his daughter from the future!

Wait—how did I suddenly become a dad?!

Huh? I think you’ve got the wrong guy...

What’s that? Your mom is Kasumigaoka Utaha?

You’re saying your mommy is Shiina Mashiro?

Your mother is Yukinoshita Yukino??

And your mom is Yakumo Yukari?!

And so, in order to save his adorable loli daughters from vanishing,

Wu Shen sets out on a grand romantic conquest across timelines.

As the youngest sister of the Hikawa family, Hikawa Tsukika faces two older sisters, one hardworking and the other a prodigy. Her sisters' care for her ultimately leads her to choose the "laissez-faire" approach. She initially thought she could just coast along, but then she encounters many girls who change her life: a small animal she met in kindergarten who likes to give her stones, a rich girl she met in middle school who is her "white moonlight," the daughter of a cucumber-flavored superstar, an elegant bass violinist who is like a mother, a vain pink-haired guitarist, and... that seemingly unapproachable but actually incredibly soft long-haired black drummer, and a wildcat-like white cat guitarist. But... can someone explain why she's sandwiched in the middle? When Hikawa Tsukika wakes up in the morning, looking at Ronai and Riki sleeping on either side of her, a question mark pops into her head. ———————————— I'll start writing from the old group, and then switch to Mygo after Mujica starts playing.

Lonely Rock + Mygo + Orange—After being pleasantly transported away by a truck, she transmigrated into the body of a beautiful, gentle, and somewhat sassy girl named Sakura Katori, and she's even childhood friends with Pochi-chan from Lonely Rock?! Because her classmates find out she likes girls, she has no choice but to transfer to Haneoka Girls' Academy, where classes don't start until May and everyone has a band. She becomes classmates with Akari Takamatsu and Ayane Chihaya from Mygo. Just when Sakura thought she was about to live the peaceful life she longed for, she suddenly realizes that both the beautiful girls in Lonely Rock and Mygo have an extremely strong dependence on her and an incredibly heavy love for her! Oh no! I'm surrounded by beautiful girls! No, it should be called… Oh my god!!! I'm surrounded by girls from multiple genders!

Every time I wake up, it seems I find myself in a new place, or even as a completely different person—a technologically advanced academy city…
