He is of anime age! Actually he's twenty-one. It's enjoyable I think. But it all depends. And yeah Nezuko is popular. It's not a bad idea to give a couple of episodes a go. Kinda gives some feel for if you're into it or not.

It could serve for some good interaction, yeah, Giyu isn't about having long conversations so maybe it could be a lot of silently hanging out and working on something together? I think that could work especially if Matt convinces him to join in one stuff. Maybe they can decorate pumpkins together.
