Tea: Hathor- Goddess of Love
Tristen: Thoth- God of Wisdom/Ma'at: Goddess of Justice
Yugi: Isis- Goddess of Protection??? (Seems to fit for me)
Oc: Sekhmet- Goddess of War/Seth: God of Chaos

I see the / being either or for they seem to fit somehow. I could see the Oc being a inbetween with each side maybe trying to go after to join them for god/goddess he/she has.
