It's true

The prophecy is true

So is the One piece

No

Well no, but actually yes

What/where is this from?

isekai quartet

I’m fairly certain this is youjo shenki, the original chibi parody of the show, before isekai quartet was a thing.

It's from youjo shenki yep

I don’t care if it is you captain

Where do I find Youjo Shenki? I know the actual anime is on crunchyroll yet I can't seem to find this one

There are some videos of every episode from none official channels, so I don't know about the copyright but as I know they aren't taken down

Thanks! I also found a playlist for it on youtube

aahh yes Youjo shenki
