Nagi is super cute, but what's new? The sculpt turned out great and the paint job is decent (his hair could have had more detail, it is pretty flat compared to some of my other nendos). He doesn't have a lot of movement, but his face-plates are great and he comes with enough accessories for every pose to be distinct. He can be calm as a prince, he can be a cocky idol, or he can be Kokona's no1 fan.
Although, that being said, I wish the Kokona cup was not exclusive and that he had glasses as an option since he does wear them often. Generaly, I think all of the I7 nendos could have had a lot more accessories. They are idols! You can do literally anything!
All in all, I am satisfied. He is a ball of sunshine (let's see if his positivety will survive during the next season of anime).
