"My Oni Girl" plays with fire, in it utilizes a lot of story tropes that drive me crazy in less talented hands. I typically hate stories where misunderstandings lead to people running away. I hate vague world building with unclear consequences. And I hate when stories take an extreme tonal shift part way through the story. But, in this film, these things didn't bother me as much. The secret to that success comes down to the likability of our main characters.
The animation and voice acting are both really good. I want to give a special shoutout to Victoria Washington who plays Tsumugi in the English Dub, she does a great job conveying all the emotions this character goes on.
The first half of the movie is almost formatted like it could be episodes in an anime series. The two leads come across various characters on their adventure and help them out in some way. This isn't a format I typically enjoy. But in this one we get to see how kind and thoughtful our main character Hiigari is. Hiigari is just the nicest guy, the type of guy that would give you the shirt off his back.
The worldbuilding might be vague, but the audience is given just enough information to keep things grounded yet mysterious.
The movie takes a drastic turn in tone about halfway through. Always refreshing when a movie keeps you on your toes.
Much like the Tsumugi, the movie might be a little demon, but it so cute and likable I can't help but enjoy it.
