Let's suppose it's true, which is the surname? Uusally Matsuri is the surname, but do you have its Japanese rumor source?

>  Matsuri Hasegawa, Yuu's roommate

Well if that's a given name and it's a surname here, probably they won't have repetitive kanjis. Matsuri as given name usually means "Jasmine", but as surname it would be written in unrelated kanjis.

And eventually, for unknown reason, Yuu's roommate was not one of the game NPC who would mean even less to BANDAI. Just not sure why they didn't pair Yuu with another game NPC...
