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?

Good news, I traveled through time and space, and it is still a peaceful everyday world.

Bad news, there is a chat group, and the style of group members is different from the normal world.

Kiana: Group members, run, I have a dual personality!

Tallulah: One hundred people challenge ten kilograms of flour to live in the snow for a week, come on! Do it, brothers!!

Toyokawa Shoko: The boss owes wages again, so annoying, it has been two months without paying wages, I think this damn boss wants to change his mind! Family, gather in Tokyo tonight! Get ready to steal hearts!!

.....

Suddenly traveled to a happy and beautiful everyday world, and also had a dimensional chat group. The two joys overlapped with each other.

I should have had a dreamlike happy time, but why, it turned out like this...

Why is your style different from the normal world!
