Hidden Survivor

[Daikinbakuju]

It has to be in a pvp match. If there's AI on a pvp match, it still counts. The private lobby sadly doesn't count, I tried it :c

That does sound grind-y and even random.
What's the total amount of gallery you can unlock?
I know each character has three different images.

1. Clothing damage.
2. Bound.
3. Soaked.

And I saw one bound pic that is numbered 77.
So counting the male characters, there's a lot to unlock.
