[@Dirty Dan] Correct, canon clans still exist. One of the two characters I will play (Since I will be playing the Sensei and a Student) is an Uchiha, the other is a Hyuuga-OC Clan I have Hybrid. 

That being said, for anybody reading this; OC clans are allowed, you'd just need to clear it with me beforehand.

[@Thecrash20] As stated just above, clans do exist.
