Physical ages of Touhou characters

A lot of the physical ages of characters depend on aristic interpretation; but based on most of them, this is my take. I still disagree with some statements putting the older girls' appearances in the 40s, considering most of them look like younger women in their primes lol.

Anyways;

Reimu/Marisa: Mid-late teens

Sanae: Also late teens

Flandre and Remilia: 13 years old

Yukari, Yuyuko and Okina: Mid-20s

Yuuka: mid-late 20s.

Aya: 20s

Hatate: Late teens.

Suwako: Early teens.

Kanako: Early 30s.

Eirin: 35~40 years old (silver hair due to being ancient)

Keiki: Mid-late 20s

Byakuren: Mid-late 20s

Nazrin: Late teens~20s.

Nue: late teens to early 20s.

Kaguya/Mokou: Late teens.

Seiga: At least 25~30.

Yuuma and Yachie: At least 30s

Hecatia: 18~19

Junko: ~30.

Nareko: 20s.

Chimi: At least 30

Ariya Iwanaga/Yuiman: 25~28
