Damn this was so indescribable adorable. what a pleasure to read.

Let's meet the Grandmothers next time

Big sis Shanghai. Excuse me while I go into diabetic shock.

I wanna see arias as a teen

Should "appeal" on page 18 be "apply"? It would make more sense.

I don't know if I can survive more of this.

Hnnnnnnnnnnnngh

Cute...

science babies are always welcomed

I'm usually not into Touhou, but this is probably the cutest thing I've seen since basically ever

Anyone got some spare insulin? Mine just ran out.

Is amazing to see Big Sis Shanghai

I still want some ReiSana though.

There are more doujinshi series of this, but I don't know where they are.
Let's see what will happen next :)

I just love those doujins. <3

Just when I thought the Kirisame-Margatroid household could not become more adorable thanks to the presence of little Arisa, in comes Shanghai.

I think I just died as well. So damn adorable!

MariAli is always so cute! Keep up the adorable MariAli goodness! Though I wouldn't mind some lewd or dramatic MariAli. They can be good to.

Cutest thing ever!!! Lovely!!!

But a bit more of Reisana in the end would have make this PERFECT.

Needs shinki as someone said, and the other onee chan. Hourai

This girls is gonna turn into the most spoiled princess in whe world of fantasy.

Yeah, Grandma Shinki would be good if there is ever another part to this.

MariAli is one of my favorite couples but Shanghai is my favorite character in all Touhou.
