It makes sense! Kind of. Maybe it's Japan's fault that she's a bit of an otaku like him, too. Like she goes to his place sometimes and she's like oh it's a nendoroid, so cute... Kiku tell me about these things! She just hides her hobbies better than the twins.

How good are Japan's grades? Maybe she asked help from him with Math or something when they were younger...

and WOW JAPAN no wonder she doesn't have a boyfriend
