Note: The Danbooru pool (currently) has over 400 pictures. The overwhelming number of them are NOT mirrored here. Additionally, translations ARE available for all(?) pictures on Danbooru as well. I highly recommend people to read the full pool at Danbooru.
Note2: Pool is not in order. See Danbooru pool for order.
Information taken from Danbooru:
A 4koma series by artist Tani Takeshi who uses yukkuri often along with normal Touhou characters.
