What do you mean zero misses in calculation? She is a teenage loli. She doesn't have any appeal PLUS it would be illegal.
With Hanabata around I'm honestly surprised anyone would even bother spending time around the two lolis. Hina kinda gets a free pass because she is pretty much made to be a housewife, even if she is small overall (proportionally she is good, but the whole thing is a little scaled down), but that aside the only one worthy of attention is Hana-chan.
