Don't worry Kogasa, she just has to frame things to fit into Futo's limited capacity for understanding complicated new concepts like "don't instantly attack all youkai you meet."
Kogasa plays with the human village kids sometimes (and because of that I expect to see such a scene shortly in front of Tojiko and Futo), so those two do have the right of it.
HrmmmIt's better to get along with youkai at least a little in order to acclimate to Gensokyo, right?Utterly harmless...Even a weird, stumpy, poor excuse of a youkai like this!?I think it might be better if you instead consider her an utterly harmless youkai aimed at Gensokyo's beginners.A high youkai would be troublesome, right?Miss Tojiko... I can hear you.
