About the Diets of Zena and Stella

Gems, fragments of stars, rained down from space, and animals that gained the ability to speak due to their power are called Zena or Stella. The difference between the two is as follows: Zena: Animals transformed by eating Gems that entered plants. Stella: Animals transformed by directly receiving star fragments. According to Fukumon, Zena has a physical body, but Feli seems to be a higher-dimensional being born from star fragments. Therefore, Zena can eat vegetables (with Gems), but Stella apparently only eats Gems. Although Zena can also eat Gems directly, they cannot efficiently absorb nutrients, according to reports. By the way, the Zenas are Shami, Shishimaru, Sarusha, Pal, Capibon, and Paoboo, a total of 6. The rest are Stella. Isn't Zena superior as an AI?
