Oooh when it comes to touch there is no doubt about it: Kane and Castalia are all touchy-feely. No surprise here, right?
She slips her fingers under his mask... he slips his hands on her back... and whether the time is right or not they are always wrapped around each other - but not in a cheesy way, more on a level of proximity that is equal to zero, since the very beginning. They way they sit or talk to each other is very uncommon and unique to a language that is all their own.
So for touch, here we go the Balthasars themselves!
