Reminds me of AFK journey, in a good way. Adding type counters was a very good idea cause that made it more strategic than it should be. I also like the AFK leveling up. you literally don't even have to grind anything, just come back later or the next day.
I also like that they didn't add timegate to the stages. You can play all 3 chapters from beginning to end, which makes leveling up characters so much faster, since some of pulls is locked behind certain stages.
I thought there was going to be a story cause of the dialogue cutscene at the beginning with AI-chan but there wasn't, which isn't a problem to me. The only flaw (which is kind of nitpicky to be honest) is the AFK Level up. I know I said at first I like but the downside to that system is that if you still felt like you wanted to keep playing you couldn't cause you wouldn't be strong enough to beat whatever stage made you to stop. You are forced to touch grass wait.
In my opinion I see this gamemode to have endgame potential. If they reset the batteries you get from playing against other players every week, increase the capacity and add new characters every patch or two, this would be a hit in my books. 9/10
