Leaving the inanely bad troll aside, something actually interesting about Guardians of Azuma is some changes they made to romance and marriage.
1. You can't lose bond points. So you can't fuck up even if you ignore the lover too long or give her bad presents.
2. You can still date multiple girls, but it's much easier because confessions always succeed and you don't have some random chance to get rejected.
3. Same-sex marriage is the same as het marriage, you just go to the Fateweaver Shrine to confirm your marriage partner. But if you want to have children, same-sex pairings bury a special turnip in the ground and the child apparently grows from that lol
4. You can actually choose your child's looks (sort of) even if they will have traits of both parents. It will also cause a 5 year time skip for each child. As usual the children have bonds and can be party members for the post game dungeons.
5. The weirdest new addition is changing fate. This means you can go to Fateweaver Shrine and jump to an alternate timeline where you were never married. This resets your current marriage partner to bond level 4 and you can marry someone else and get the diferent children. Nothing else resets (not even the endgame dungeons), so you don't lose any progress.

They seriously want you to be able to experience everything in a single playthrough this time, huh?
