I don't know about HI since I've never played it but GI seems too mainstream for canon gay couples, even with lesbian fanart/noncanon shipping you'll see the usual down bad weeb that gets angry because another female from the same game is "stealing" his waifu. Tired of it, but there's really nothing we can do.
^basically. As usual with unorganised religions that don't draw on a specific central Scripture (which have disputes over interpretation instead...) there's an awful lot of variation in the details, and a given myth or divinity might be startlingly different between localities.
^I know Mirei is lesbian but they are saying Hoshikawa is Bi which is unheard of for me. I thought she was straight because when Matsuri confessed to her she said she likes boys.
