Naru as Princess Gaia Picture

In a sailor Moon fanfic I am doing, Naru is the princess of earth.

Since there is some mythological aspects in sailor moon, gaia is taken from ancient Greek religion: Gaia ( /ˈɡeɪ.ə/ or /ˈɡaɪ.ə/; from Ancient Greek Γαῖα "land" or "earth;" also Gæa, Gaea, or Gea;[1] Koine Greek: Γῆ) was the primordial Earth-goddess.

she is a reincarnated sister of Endymion. In her current life, she is not related to Mamoru, but her powers are.

She's semi-canon? eh... yeah.
