I don't see this game popping off, it's probably going to follow the typical IP/Anime-related mobile game cycle like the Jujutsu Kaisen and My Hero Academia game. I feel like "current-gen" anime isn't really suitable for mobile games (especially gacha) because they are shorter, resulting in less characters and content devs can utilize. It would get a huge launch because of the popularity of the IP, but usually won't last long.
Successful mobile games focused on a popular media franchises have 3 things in common.
1. Has a huge community/fan base
2. Has a long history
3. Has a wide range of characters, weapons, or anything of that sort
Examples include Dragon Ball, One Piece, Naruto, Marvel.
There were some that did decent like Seven Deadly Sins made by the same developer or Isekai Slime, but even those eventually fell off. Games based off of current-gen anime would be better off with a b2p game imo, like Demon Slayer. Or just stick with collaborations of already successful games like with Monster Strike, etc.
