After Bai Ge resolved the crisis of "nothingness" infecting the world and successfully saved a part of the universe, he suddenly found himself entering the body of a young girl. He accidentally joined a chat group and found the person who had exchanged bodies with him.

then--

Chihaya Aine: The band and the like are a nuisance. There are so many worlds waiting for me to save. Transform!

Fernina: I am no longer powerless. I can save everything in Fontaine! Including my half body! Transform!

Mei Raiden: The power of this body is not destruction, but hope. I will dispel the darkness and awaken the light! Transform!

Black Rabbit: I will never again shrink back and hide behind everyone. I will use the power of love and hope to defeat the darkness that overturns the little garden! Transform!

Qingque: I had to work before I changed my body. Now I have to work? That would be a waste! I just want to go out and play today. Even the Star God can't stop me! Transform!

Qingque: No, how come this transformed one is weaker than my original form?

…

Bai Ge, who is practicing guitar on someone's body: ...

So, when can you get my body back?

I wondered why I was standing here. Oh, that's right! I traveled through time! I traveled to the world of the magical girl Puella Magi! But wait, this plot line seems off! How did I become Puella Magi!? And a magical girl?! But if I'm a magical girl? Then what is this Salvation Witch's Lament Seed in my hand? ...Oh, so there's a real Puella Magi! ! But wait, aren't there too many Puella Magi? Why do I feel like all of these Puella Magi have a bit of a sister complex?! And me! No! Yes! A sister!!!...Wait a minute... "That... Flame Demon, I'm really not Puella Magi!" "Wait... You... Don't come over here!!"

Travel through a world invaded by disasters and awaken the sign-in system of all worlds.

He thought that signing in in this world and obtaining the power of a Ruler of Reason, which was enough for him to protect himself, would be great enough.

Unexpectedly, he was selected by the dimensional chat group and got the opportunity to sign in to other worlds!

I originally wanted to head towards the end of the trees and the sea, but I found that I met countless beauties in the process.

Kasumi no Shi: "Tsk, what an unlovable leader!"

"You left a deep impression by being a hero saving a beautiful girl, but now you want to just walk away after you've been seduced?"

Eriri: "Damn it! I was here first, and the twin tails were supposed to increase attack speed! Why don't you come up and attack!"

Esdeath: "This man is stronger than me. I can't match him in terms of strength, but I must conquer him in other aspects!"

Lei Movie: "He saved his sister, if he wanted to..."

Banned for swerving during the Spring Emperor's Trophy, Sakura Baimu has become a trainer at Tresen Academy. After training the Triple Crown East Sea Emperor and Mejiro McQueen, who won the Spring Emperor's Trophy three times in a row, Tresen Academy welcomes a new batch of ponygirls. On the day of the entrance ceremony, Sakura Baimu arrived at Chairman Akikawa's office and met Kita no Genju and Satomi Kozumi, who were waiting to join the team. "Well done! Who would you choose to train as your next Triple Crown ponygirl?" Chairman Akikawa asked with a smile. Just as Sakura Baimu was about to open her mouth to answer, she suddenly saw a system interface appear above Chairman Akikawa's head. [Akikawa Yayoi: Training Difficulty (C)] Sakura Baimu smiled softly and pointed a finger at the older girl with long orange hair behind the desk. "Wha...what?! You want to choose me?!" "Of...of course not!" "Think about it carefully!!!"

Equipped with the cheat code for Dark Dungeon, Doc Otter arrives on Terra, the land of the beast-eared girls. By equipping accessories, Otter can establish a mental link with the heroes, enabling micromanipulations like sniper operators moving five centimeters to the left... or forcibly breaking through mental barriers and taking over anyone's body! He's the protagonist, yet he's become the villainous boss... Wait? The cheat code is Dark Dungeon? No "1" suffix? That's fine. Is the protagonist and the boss the same person? Unusual? Not at all. Traces resembling an Iron Crown have been imprinted across Terra, following the footsteps of the Rhodes Island land carrier. Looking back, Otto couldn't help but sigh... There was a shark who had mistaken him for the "Lord of All Things" and who pretended to be sick from time to time to take advantage of him after waking up; a killer whale who seemed cold but was actually stupid and sold herself to him without knowing why; a self-redeeming dragon girl; a hypocritical bomb maniac; a premature bread maker; a Hippogriff female teacher with a collar and tied up all over her body... and Kal'tsit made a handgrip dynamometer gesture from a distance: A bread maker, right?

Yuigahama Yui: For the first time, I found someone I liked and made a lifelong friend. These two joys intertwined...
