@no0neknows imagine all the suicide that could have been prevnted if people didn't call troubled people faggots and, instead, tried to understand and, possibly,help.
What is the source of spiritual power? Can it be learned? I'm interested, because that granny didn't mention the possibility of teaching Miko, but at the same she seemed to have her power restored, when she went to the mountains, which may imply that spiritual power can be gained somehow.
@GrayBypasser it's probably something you can train if you have it, but not likely something anyone can gain. At least that's the impression I got so far, but it's really up to the author, could go either way.
BTW I think obaa-san got stronger by working the field, which I find hilarious. I guess that's one way to strengthen your connection to the earth spirits.
