Nope turns out I am definitely wrong. They constantly talk about Hina being young in the second book so Hina has to be younger. He still looks good tho (づ￣ ³￣)づ
Hina is 20, it is Shige (the boss I think?) the one who is 6 years older than Chii ;)
Wait so Chii is 27... and Chii said that Hina is 6 years older than him. So Hina is 33. He looks damn good for 33, though I suppose all anime characters that aren't literal children or elderly look 20
