I really love the idea of this series, but the execution of said idea could be better.
The premise of a brother who end up looking like a siscon because he protects his sister all the time but in reality is actually trying to protect everyone from his sister is so interesting. The only problem is that a good concept can only go so far. I wouldn’t say this that often but I feel like this has the potential to become a lot more action based, the problem is the art style is lacking.
The Characters are fun, especially are two leads.
Overall I would recommend this series, especially if you’re a fan of the creators other work Takagi-san.
