Kannazuki no Miko is widely known as a yuri series, but it’s also been described as a bisexual love triangle. So the most important male character, Souma Oogami, tends to get some hate from some of those who watched the series only for the yuri.
(This post will contain spoilers for most of the series.)
I think this is undeserved, for several reasons, but let’s just start with this. We are talking about a series in which a character who had to choose between two love interests of different sexes chose the one of the same sex, and it wasn’t because there was anything wrong with the opposite sex option or because she suddenly realized she was only into girls. How many times does that happen?
I don’t think Souma’s good qualities not related to the triangle situation really need much defending. He’s hotblooded, decisive in the midst of angst, and a rare (in anime) illustration of how the personality of “the hero” adapts into a supporting role.
Souma is sometimes considered an example of the “male interference” yuri trope, but he’s hardly a textbook case of it. For starters, he doesn’t know he’s interfering with anything; he may or may not be aware of Chikane’s feelings for Himeko, but he definitely hasn’t seen any indication that Himeko might be romantically interested in Chikane at any point before the last real romantic interaction between him and Himeko. (And the margin isn’t even a small one if you don’t count things like the fact that the manga he buys for Himeko is a yuri one. Incidentally it’s also by Reiko, and Himeko being one of her fans is arguably the greatest relevance Reiko even has. (I swear I don’t hate Reiko or anything.))
