Lanya (also known as Madame Ping and Streetward Rambler) will be released as a playable character in version 5.4. She is a 5* Polearm Girl.
5.4 will be the Lantern Rite patch and will also see the release of a new 4* Catalyst Girl.

Also I apologize for leaking these in the reverse order. The new characters added in 5.2 and 5.3 have already been leaked, but just to clarify:
5.2: Chasca (5* Anemo Bow) and Ororon (5* Electro Bow)
5.3 has Mavuika (5* Pyro Claymore) and Citlali (5* Cryo Catalyst)

Apologies for the mistake, Ororon may actually be 4*.
