I mean this is a must in a Naruto world right?
So here are the candidates that I was thinking.
1. Tsunade (I mean obviously ;)
2. Ōtsutsuki Kaguya (My precious rabbit goddess waifu)
3. Hinata? (Honestly age difference would go crazy so..)
4. Kaguya Bell (Oc from the Kaguya clan)
5. Uchiha Rumy (Uchiha Oc)
6. Ayla (Oc maid)
