Senadina and Dreamseeker can sing in new map??? [Honkai Impact 3]

Sena sing when we just left her idle, meanwhile Dreamseeker sing when we enter her house.
Dreamseeker voice is so good. I don't understand what their saying because I don't learn Japanese language but singing is singing!
Their JP VA :
Senadina : Minori Suzuki
Dreamseeker : Yuki Nakashima

Dreamseekers singing is translated by the game itself,
When you go into the option of Astral OP/Elf and go on dreamseeker she has some voicelines there, even her singing line
It says something like "I've gone through the worlds and was accompanied by a marmot"
