Thanks for uploading such a fun story! Even if Danbooru suddenly decided to be a Seija-level bitch, making translation a bit of a pain. There are still some bubbles that the site simply hecking refuses to save/edit, but nothing too major. I'll try to add them in later.
I definitely think Seija and Shou are an underplayed pair what with the whole Bishamonten / Amanojaku connection. Finally a doujin that covers their epic struggle.
