The content of the conversation is not too difficult, but there are many topics of mafia struggle and revenge, so it is an animation for advanced users in terms of learning Japanese. However, it is difficult to recommend.
Each character speaks differently, but I want you to rest assured that it’s almost realistic. This anime is a drama containing fantasy elements, but there are not many difficult words. There are many variations of difficult words, so if you are an advanced Japanese language learner, it will not be bad to try this anime.
Needless to say, there are many splatter depictions that are not a part of learning Japanese. It goes without saying that there is a problem as a learning subject in the first place
The two heroines are high school girls, but because there are many adult conversations, difficult phrases and high-level honorific words often appear. Because of the world view of the work, there are many youkai and police-related terms, so if this anime is really suitable for learning Japanese, it is limited to advanced learners of Japanese.
Since all the characters are junior high school girls, the difficulty of everyday conversation is not high. If you are a Japanese language learner and above the intermediate level, you can challenge to watch this anime.
Because the genre of the work is S / F, the appearance rate of political and military terms is high.
It is an anthropomorphization of the Japanese fleets during the Second World War made into a character of girls named “艦娘” (かんむす, kanmusu) . Because there are so many characters, there are many Kanmusu who speak in a distinctive way of speaking which leaves an impression for each characters.
