Touhou Ibara Kasen ~ Wild and Horned Hermit.

In this 10 volume official Touhou series, spanning the time period of nine long years between the UFO and WBaWC games, we follow the misadventures of the business inept shrine maiden Reimu Hakurei and her ever-curious friend Marisa Kirisame, who meet a mysterious, young hermit woman named Ibara Kasen. Upon seeing how sloppily the Hakurei Shrine conducts its business, she decides to become a regular shrine visitor, determined to lend her near unlimited wisdom to the shrine maiden, in order to make her place a proper Shinto Shrine. Does the nagging, yet well meaning hermit bring nothing but good-will with her advice, or is there something more sinister hiding behind the friendly face and her bandaged arm?
