I always assumed she was early to mid 20s. Older than characters like Ken or Tan Hi, but younger than Rou.
If I were to guess ages of the main groups/antagonists of the seasons it'd be something around the lines of
>Fucked up magic altered aging that can't be pinned down
Duck, Kei Gai, Azibelpher, Demon King, Byakuren (Pili watchers can tell me otherwise for Su Huan Jen here I guess)
>65-70
Old man Seal Guardians, That guy who made the Index, Locust
>40-50
Shou, Ban Gunha, Sharp eye Impaler. Trapped wizard
>30-40
Screaming Phoenix Killer, Mantis, Spider, Centipede, Monk, 10Guy
>25-30
Rou Fu You, Tenmei, 10GUY's Lieutenants, Fox
>16-24
Chao Feng, Ken, Tan Hi, Scorpion
