What’s Nara age tho?

I'm certain he's above 10. At least we know the prince is 22

when the prince was 12 Nara was clearly older so he was maybe like 17-20 years old (unknown). Since prince is 22 now, Nara could be like late 20's????

actually its more likely Nara was 15-17 so he'd be mid 20's

I actually thought Nara was 20 so he's 30 by now maybe.
