Although there's no real indication of where a certain student should belong to, I thought ab some main characteristics of Hogwarts Houses and made a list I thought was the most accurate one.

Hufflepuff are genuinely kind people among anything else. Their motivation are friends and they'd do anything for their loved ones. Best people.

Gryffindor are similar except they know how to mind their own business. They're more active, focused on their goals and possess admirable characteristics of being brave and strong willed.

Slytherins are charismatic, mischievous, sometimes rude and depressive. Awfully sassy or awfully sad, you choose.

Ravenclaws are serious, like to read books, analize things, being creative, having unusual hobbies or simply being special in their own ways.

Hufflepuff - Shirudo, Jodi, Shimizu, Shizuka, Kagaya, Chimoku

Slytherin - Chance, Eitoku, Nico, Kaon, Cortney

Gryffindor - Sofia, Hanako, Saiyuki, Akira, Guren, Jiten, Tatsumaki
