The 'Valley of Lost Girls' novel could revolve around the mystery of the valley where these girls are. It might be a story of adventure, with the girls facing various challenges in this valley. Maybe there are secrets hidden there that they need to uncover. There could also be elements of self - discovery as they try to find their way out or figure out their place in this strange environment.
Not having read the book, I can only guess. The main characters are most likely the girls who are lost in the valley. These girls could have different personalities. For example, one might be the cautious one, always thinking about the risks, while another could be more impulsive. There might also be a character like an old hermit who lives in the valley and has some knowledge that could either help or hinder the girls. Additionally, there could be family members or friends of the girls on the outside who are worried about them and trying to find a way to reach them.
As of now, the Genshin manga is not finished. The story is still evolving and there's more to come for fans to enjoy. The creators are taking their time to develop a rich and engaging narrative.
There's no definite answer yet. It might continue if there's enough demand and the creative team has more story to tell. But it could also stop if they feel they've completed the story arc.
There is a Genshin Impact manga available. It brings the game's world to life on the page with beautiful art and engaging storylines. It's a great companion to the game.
