Ayato in Diabolik Lovers is often portrayed as confident and somewhat possessive. In Ayato x Reader fanfictions, his character traits are usually amplified. He's shown to be highly attracted to the reader and will go to great lengths to keep them close. His vampire nature also adds an element of danger, as he may struggle with his blood - thirsty instincts while being in love with the reader.
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.
