Why cant we have good action ecchi anime? 
Ayakashi are strange, supernatural creatures invisible to the majority of people. Though most are harmless, some ayakashi attack humans to devour their life force. Exorcist ninjas are tasked with protecting people from these spiteful spirits.
Matsuri Kazamaki is a young exorcist ninja born to a prestigious clan. His childhood friend, Suzu Kanade, is an ayakashi medium—an individual with immense vitality that attracts ayakashi. Matsuri deems all ayakashi threatening and wishes to keep Suzu as far from them as possible, but this clashes with her desire to remain close to them. One day, the pair encounters Shirogane, the "King of Ayakashi," who is hellbent on consuming Suzu. As she is about to be eaten, Matsuri comes to the rescue and manages to seal the ayakashi's powers—but not before Shirogane takes revenge by turning him into a girl!
Until he finds a way to transform back, Matsuri must adjust to his new, peculiar lifestyle while fighting against hostile ayakashi. Moreover, Suzu is now conflicted about her feelings toward Matsuri—further plunging their relationship into a state of ambiguity.
Lets just say I was kinda put high expectation from this series. Mainly because it was created by to-love-ru series author so I kinda expect the usual ecchi tag. Combine with potential action and genderbender, surely it will be easy win?
Series started with usually protector & childhood friend, which lead to destined encounter with king of ayakashi that just want to devour his friend because of her amazing hidden energy. After the genderswap, the stories continue with usual "tackle one ayakashi encounter" in every episodes, while throwing in new characters with their own quirks. The king of ayakashi somehow turned into annoying cat mascot that followed the protagonist duo. Once a while, there is couple of nice action scenes, but albeit quite short.
The series sadly didnt offer anything new. The ecchi fan service isnt that interesting nor the action side of the series. There are couple of mundane school life episodes, but it doesnt bring the usual warm feeling either. In the end, the series just arent strong in any aspect. No romance, no comedy, not much action, not much good feeling. I would say the animation is quite good, but is still average with not much "money shots". At the end, the series have nothing to write home about.
Again, I set expectation abit too high for typical average ecchi action anime. Even among of similar genres, it is bottom of the barrel tier. Below average (usually ecchi show get super low MAL score) even for my standard.
