cyclop girl seems good for a gunner (but im not a big fan of it)
assasin squirrel with a healing job for me is a bit weird, since this 2 is different job, but for self healing like kurohime is still ok (not a full scale healer) also we already have enough assasin for it
trap is a no for me, and i think angel is more suit with staff rather than a gun
rat or mouse girl might be good with gunner, since they can have agility, maybe like double step or something (in my personal opinion)
furry girl might be more general for a job, and probably can suit in this job too, maybe like half angel and half doggirl or else? kinda similar like lili
