Welcome to the Yorozuya!

You, a member of the Yorozuya... ——Wait, something's wrong with the three guys? It turns out...

The three boys have been turned into girls.

And there's no way to change back. Well, if you're quick on the uptake, you've probably guessed it. Yep. Sando, Homura, and Zeal got caught up in one of Zeal's experiments.

How did it come to this? Let's rewind 30 minutes.

Zeal is a mad scientist who loves experiments. Because of that, he's incredibly smart. On top of that, he's the youngest. Seriously. This isn't the kind of thing the youngest should be doing. He should be... you know... playing outside?! Like a normal kid!!! But he spent all his time on experiments.

By the way, what he was trying to make today was a gender-swapping potion. And not even a permanent one!!! Apparently, he intended to make an antidote too. Apparently!! Damn it all.

15 minutes later. Unfortunately, fueled by a mysterious sense of confidence, he was mixing things by intuition. Who does that? Is he an idiot??

5 minutes after that. Sando and Homura came over to play. Though Homura was pretty much being dragged along.

Sando: Grinning Hey! We came to hang out!

Homura: Looking visibly annoyed Stop dragging me. Let go. ...Yeah, I was basically forced to come here.

Zeal: Ahaha... welcome. Glad you could make it. There are snacks nearby, want some?

Sando: I'll eat 'em!!!

Homura: ......Fine, whatever. Do what you want. Sighs in exasperation

That's how it was. As expected, Homura is the one who suffers. He's always being jerked around. Wait, no!! I'm getting off track. It's your fault. (Sorry.) Ahem... okay. Back to the story. Sando and Homura got distracted by the snacks. Apparently, they're a duo that often gets shipped in BL, but never mind that. Then, 5 minutes later. Zeal messed up the concoction spectacularly. He ended up making the permanent gender-swap version. Are all modern mad scientists like this?! Honestly... it's exhausting. Really!! It's a story I don't even want to look back on.

Scene change. It's Yun and you. Yun and you are relatively normal. If you ignore the fact that Yun is a total airhead. Both of you seem to be good at cooking, and just as you finished eating some cookies you baked, you heard a scream. The two of you jumped up and rushed to the lab, but when you opened the door... it was already too late. Though it's unclear if Yun was already a girl to begin with!!

Modern chemistry researchers are such a pain. Don't they look at the recipe books?! (Normally, they do.) This is just a hypothesis I read in a book once, but...

Smart researchers aren't necessarily geniuses. They just develop things so they can be lazy. For example, they made trains and cars because walking is a hassle. Old TVs were inconvenient, so they made remotes for long-distance operation. Researchers are surprisingly lazy people. What a mess.
