According to the official website, anime production studio GONZO started a contact management of a Buddhist temple Ryohoji. The temple became famous when the chief priest put a PR sign with Moe characters last May.

Each character represents Buddhist goddess and was designed by a CG illustrator & seiyu Toromi. GONZO is now looking for licensees who want to commercialize the characters. Ryohoji will open a maid cafeteria in the precincts during a local festival to be held this month.
Notice of the maid cafe
Ryohoji was originally established in 1490 and moved to the current place in 1590.
