I am in disblife, that this shipping even existed!
But I like where this is going.

Yohane is confirmed to be female right? Because until now I've only seen people call Yohane as "He," "Him," and "His"

. . .The manga and the anime almost have little or no relation to each other.
I never expected Yukari to be the first person narrator. . .

It's been along time for any fuantei to be finally posted here.
This book is nothing like the others.
Their style looks sort of like Warigaki's too.

Also a few points I wanted to ask about - Is Yukari really that powerful? Im not a huge touhou fan so havnt read THAT much - but I got the impression Reimu pretty much kicks everyone elses ass but here she seems to be loosing to Yukari - who is a gap youkai yes?, even tho Reimu beats gods up etc? I couldnt find much info on the characters relative strengths.

Yukari and Yuyuko are suppose to be one of the most powerful yokai that have lived over a thousand years and since Yukari has the ability to control boundaries, she can manipulate tons of things.
Sometimes in fan works Yukari is shown to have known previous Hakurei mikos, long before she met Reimu.
So Reimu would certainly have a quite challenge, considering Yukari's experience fighting for so many years.

So this is the only manga here that is going to be the manliest?

This is probably the best Renko x Maribel book I've ever read.

Dat Utsuho smile on the cover.
