Welcome to Project KV where fans can't help but speculate this is blue archive but with swords!
It came from some of the original staffs from nexon, the company behind Blue archive~
And few days ago after days of teasing they released a PV!
Sadly this game is simply a dream we can't have because they announced that the game will be cancelled and terminated. The reason are unclear but some speculate that it might be associated with failure to secure staffs. investors and controversy about a blatant plagiarism of the game to blue archive :3

Ps. for some reason Project KV became popular in twitter with questionable arts ( ͡° ͜ʖ ͡°)
