The reason killing the goddess of love kills Tia was explained earlier. I think it was that immortal emperor who was saying that killing a god would place a curse on the killer, and that curse would be related to the type of God, so they were wondering if he had killed a god of time to cause the looping. Instead we find out he killed the goddess of love, so the curse that comes with that is the person he loves dying ig.
I think the reason it keeps looping is because he is the demon king. So the timeline requires the hero to kill the demon king to naturally progress. The MC is no longer the hero because he now has the role of Demon king, so the summoned new hero was the only one that could be allowed to kill him to have the natural order continue to progress (I would assume? Though I think he's about to come back so idk). I'm thinking of it like a glitch that the world keeps trying to correct, so it loops again and again until the correct progression takes place.
That's what I got from everything, I'm sure if I remembered the rest of the manga properly itd make more sense haha
Thanks!! That clears up a lot of questions I had ヾ(❀╹◡╹)ﾉ~
The new chapter makes things a lot more confusing, but at this point I'm just writing it off as time travel BS (|| ￣_￣)
Trust me, I'm rubbing my little amount of braincels together so fast it's starting a little fire in my brain. Sometimes you just gotta read a manga and accept things at face value, because aint no way I'm gonna understand all the lore properly! No shame
Is the goddess we see at the start a fake? Did cage killing the goddess immediately kill Tia? That seemed like it all happened in one lifetime since that was the only time he was growing older... Wasn't killing the goddess the thing that caused the time loops, and not becoming a demon king, whatever that means?
His original fate was to kill the demon king as a hero, so becoming a demon king makes a loop...how? Wouldn't suicide kinda mean that the hero 'killed' the demon king, unless there was some rule that said the hero can't die? Is the first emperor just a background npc for cool fights, and did the job class system actually matter?
What even is the story??
