NDRV3
1.Kaede- Amity (bc shes a pianist and according to Divergent series all artists are Amity)
2.Shuichi- Erudite/Dauntless
3.Gonta- Divergent Amity/Erudite(bc hes an entomologist and he's not that dumb as fandom claims)
4.Himiko- Amity
5.Miu- Erudite
6.Angie- Divergent Amity/Abnegation(Bc shes religious so it's a blend of both)
7.Kirumi- Divergent Erudite/Abnegation(bc shes a prime minister and she serves the country)
8.Rantaro- Divergent Abnegation/Erudite/Amity(bc he survived so he must have a brain and bc he seems like a nice guy painting girls' nails xD)
9.Korekiyo- Divergent Erudite/Amity( bc I think that humanities are somewhere between the two and he's pretty spiritual )
10.Kaito- Dauntless(DUH)
11.Maki- also like Kaito(DUH), but as she enters the killing game she pretends she is from abnegation
12. Tenko- Dauntless(bc she's martial artist)
13.Ryoma- Dauntless(duh)
14. Keebo- Erudite bc he's a robot
15. Kokichi- Divergent Erudite/ Abnegation(!)/Dauntless/Candor( In the game he states he is both erudite and dauntless but hides abnegation because he does not want to trigger the "DICE members being tortured" memories he is Four, he just can't be kind, see I told you Saiouma is meant to be bc Kokichi is Four and Shuichi is Tris xD)
6.02.21 UPDATE xD
Ahh I now I remember whom have I forgotten:
Tsumugi ( aka. Tsum tsum)- Dauntless fro transferred from Erudite
Now I am confused bc I must have forgotten someone bc in Drv3 there were 16 students but I don't know whom I have forgotten, plz bear with my forgetfulness
