With gunner, I meant someone who uses a weapon against enemies - that could be a bow, a crossbow, or a bag full of stones to carpet-bomb someone, whatever.
Anyway, it is quite easy to get to Hotaru, there are 2 ways to swim there and it's not like they were hidden
Also, as you describe it Myomoto, it'd be great to pick people off the air, seeing how they can't fight back, it would be safer to run away with actual ground for your feet to touch
. I still say it's not necessary, rather improve Zeppelins and maybe add a place to craft them to main, along with a shop that sells packages of required rescources for outrageous prices
