Rinnosuke went a little youkai on them to stop the fight?

Hmm... isn't all those pictures related to CoLA?
I mean, the art style and the story is pretty much related

So Rinnosuke transforms... during an eclipse?

It's by the same artist, but it's not related to it.
If you can find it on his Pixiv-page, don't tag it as CoLA since it's doujin work.

Asai Genji drew the artwork for CoLA. You can tag posts with curiosities of lotus asia if they reference or parody the original work.

Mmm. The pool is called "So you can enjoy Touhou Kourindou", so I guess it's CoLA stylized.
But I honestly don't remember the picture involving Tokiko and a hatchet, nor this picture. I think I'll remember such things.
Did the artist tried to spoil CoLA and went drawing random stuff?

Ah, you're right. The way he draws Sakuya is so similar, I didn't even bother to check again. He is definitely referencing CoLA.

This is actually drawn as a "What If" situation. In this case, Rinnosuke went after the two people that broke his cup after the event in chapter 5 of CoLa. With his glasses off, I am going to guess that he must be really wanting to get them...
