Wait wtf? how old are both of them?

At present Towa is 28, Griz is 32, HOWEVER when they met and fell in love Towa was 13 and Griz was 28. The time flow is wonky between worlds, for Griz only 4 years have passed but for Towa it's been 15.

I know, it's weird. Griz was weird. He's still weird now, just in a different way.

Thanks for clarifying-, the time being so wonky made it confusing but.. Griz dude cmon.
