moka and kunikida work that the armed detective agency together which a bunch of other people. But theres one small issue. Kunikida and moka are paired together but nanami and kunikida HATE eachother since they grew up together due to being under care of Yukichi Fukuzawa kunikida and moka were both orphans (since moka's family all died). And from then kunikida seemed to hate how childish and hyper moka was and would sometimes make comments on it.
