Spoiler for Episode 11:
It was indeed the best episode for me. First part is straightforward comedy until two revelations where made : the first fact was Ashiya can control onmyodo and the second fact was Takuma has a Oni (Japanese demon) sealed inside him and he's the cause of everything. Tamaki finally realized Takuma's true intentions but I keep questioning myself whether Tamaki is Princess Tamayori or not, but I do enjoy the twists nonetheless. I'll cross my fingers on the next episode (the bonus that has chestnut cake sounds delicious !
).
