Right now, the faith of Moriya Shrine is supported by Kanako. If the faith on Kanako waned, our life will surely be affectedIn the previous battle, Kanako lost to human. Kanako the War God lost. Even if it’s a danmaku play, the fact is that she’s surpassed by humanFor a war god, that’s very dishonourable. Of course, faith is also affectedThat’s why Kanako can’t let any more faith disappear. For that, she needs to live without wavering on even the smallest matterYou can’t expect any positive effect on faith from showing a war god using the toiletEven so… it’s just the toilet…It’s not “just”A god who lost faith is miserable.
Having no authority and no respect, really not much different from any other fairies from around the placePerhaps, that’s her reason to refuse using the visitor’s toilet
