Viewing post in How to use kiss feature and avalon stuck
I found a way: if you use Schrödinger (the cat girl) and use "All-In", she will kiss Avalon and be swallowed up inside.
If you don't want her to get swallowed by accident, feed her as many prey as she can eat and feed one to Avalon so that if you use "All-In" later she won't get eaten due to her belly limit.
