Impact cannon is recoiless (though by theory, they're FAR from recoiless, after all, they spew compressed air like crazy
)
Another kind of ranged weapons... hmm...anyway...
Ichika seems to be idealistic enough not to let people in trouble (such as Rin's and Charl's case), otherwise, he tend to ignore some people because it bothers him to even care (such as Cecilia)
