yeah that happened to me with anemone when i was soloing a boss xD

I think its a bug > the reason being even if the girl in the video gets hit, not evading her HP is not reduced and it triggers the multiple counters.
I have a counter / evade team on DMM and I have never seen for the counter/super counter to get stuck like this where the cinematic of pest receiving damage gets reset several times, then the pest disappears, then it appears and then suddenly you win.
It looks more like some error or missing line in the code, since the mechanic works, but it clearly should not be doing this.

But then again... what do I know, I am just a simple mofu :3

This is very clearly a bug, and I can confirm it never happened on DMM.

I kind of wish it did, though. That would make Re: Sakura & Ume a joke rather than the nightmare they are.
