Here's a list of curious winter anime...
Youjo Senki: A story featuring a salesman who annoys God and becomes reincarnated as a young bratty-looking girl in a world of war and magic. I like the tag 'Saga of Tanya the Evil'...I'll probably watch the first episode because the premise sounds funny.
ACCA 13-ku Kansatsu-ka: based on a manga by Natsume Ono is about a government inspector who does his job. The world looks interesting for a slice-of-life manga.
Spirit Pact: a fantasy BL story based on a Chinese manhua...actually looks fairly mediocre, but we'll see.
Tales of Zestiria the X season 2: more of the high budget fantasy anime.
Ao no Exorcist: Kyoto Fujouou Hen: A return to the manga's plot rather than original anime fillers. Hoping for some fun shounen action.
