Kasane Teto's official age is stated to be 31 years old. However, because she is a chimera-a hybrid of human and mythical creature-there is some ambiguity and fan interpretation around her age. Some sources mention that while her human age is 31, her "chimera age" is about 15.5 years, which aligns with her youthful appearance and voice
. In summary:
- Official age: 31 years old
- Chimera age (fan interpretation): around 15 to 15.5 years old
This dual-age concept reflects her character design as a youthful girl with a mature official age, and it is accepted that fans may interpret her age differently depending on the context
