SPOİLER AHEAD CAUTİON
(İts very long but still not everything and detailed)
1. There are the fragments of the brilliant light (basically gods servants aka angels) and the sovereigns ( there are 9 of them)
2. The shadow sovereign needed a body to descend to earth and he chpse jinwoo because he was always nearly dying in each dungeon he went in so he was perfect
3. Jinwoo will fight against the other sovereigns and kill 2 or three of them and then gets himself killed to just activate his second heart that the og shadow sovereign gave him so jinwoo fully becomes the shadow sovereign
4. There is a huge war against the bad guys and he almost loses so he asks for help from the angels and the angels turn back time to 10 years ago when tehere werent any dungeons and whatnot
5. Jinwoo fights against the sovereigns in a dimension where nobody exists so that the humans dont get harmed ( he fights against them for a long time i dont remember the exact number)
6. Then he comes back to earth and marries has a son and yeah
7. BUT that whole turning back time thingy made the people forget him so nobody remembers and knows that he fought for them all alone against armies just so they wouşdnt get harmed which is frustrating and made me almost cry ( he friggin sacrificed himself (╯°Д °)╯╧╧
8. The next arc coming up is the one where he goes to america and pummels the national rank hunter “whatwashisnameagain” (⌒▽⌒)
He is a significabt character but sadly we wont see much of him only at the moment where jinwoo inheritd the true power of the shadow sovereign when he shortly dies .... the father protects him when he lies there unconcious ... he then dies ... jinwoo and his father have a short moment together before he becomes dust ... he just vanishes ╥﹏╥

I am in desperate need of spoilers, hit me with everything you got
