Moe Hime

The time is the Heian Era. It is rumored that Tomoe, the princess without a consort, is extremely shy. She rarely attends events at the palace and just stays at home. However, in reality, Tomoe-hime is making use of her natural talent to enthusiastically compose and illustrate waka poems, or rather, "doujinshi" (with the Emperor as the top). A historical story about the friendship between a fujoshi princess and otaku youkai!
