Kenn's Comment: A funny 4 koma series about Udongein Inaba Reisen, which'll have you really feeling that she's pulled the short end of the straw, every single time. Reisen's one of my favourite Touhou characters, and is competed for 1st place with Reimu ^^" 

The art work is cute too ;D I don't think you really need to know too much about Touhou to enjoy it, as there is a bit of an intro to the manga that explains a bit. Aside from that, I don't think there's really anything that would need explanations in the manga.

Summary from MangaUpdates:

A Cute and funny set of stories about two Rabbit Girl yokai - Reisen Udongein Inaba, Tewi Inaba and an Exiled Lunar Princess - Kaguya Houraisan along with Reisen's Master - Erin Yagokoto, and their everyday life in Eientei.
