I Was Caught Up In a Hero Summoning, but That World Is at Peace - Chapter 51

So him, 2 girls, and another guy were summoned to this world. The other guy was the hero, the rest were extras. The world didn’t need a hero but just magic kidnapped them for festivals and symbolic tradition, which is pretty messed up, but at least they can go home in a year. So far we haven’t seen the hero at all. The two girls are living with mc and just chilling and learns Ng magic. There is also the original hero from 150yrs ago who stayed and got a new demon body and goes by nuen with her fairy friend, but she has only showed up a handful of times.

MC is weak but has the power of heart, aka sympathy magic, and makes everyone like him by him just being a good guy. He makes friends with kuro who is underworld king, one of 6 demon kings, and she kinda seems like she is in love with him. He also makes friends with almost all the other demon kings including the death king who definitely loves him. Another possible love interest is the head god who blessed him and he owes a date to. Then the girl who summoned him and her elf friend / knight also seem to be possible love interests. Plus there was a female emperor of another country that’s into him.

There isn’t really an antagonist, closest would be the phantasm king who got the war king and dragon King to antagonize a bit, but that settled real quick. She also said that she did those things to test him and strengthen him so he could save kuro but unknown what from. The most recent event was Alice kidnapping him, and it was just revealed a few chap ago that she is working for the phantasm king.

So as it stands there are still a few big questions hanging like: save kuro from what? Where is Alice taking him? Will he go back home or stay? What the hell is going on with the hero that hasn’t been seen since page 1? How many wires is he gonna have?
