I'll try to summarise as much a possible:
I give this a 9.9/10 because this shit is so fucking hard to summarise properly becuz everything is literally connected
MC was summoned from another 'world' by Himel and that other sheep. Himel gave him a sheep to guide him towards the destruction of the world. He was summoned by Hamel to give supply to the world (which is just a simulation that Meltier created? But it ain't real.
The real world is already as good as dead because the world is flawed.
God hated it and wanted to leave the world. But Hamel and King and Maltier was like nah bro ain't no way u leaving. So they used the labyrinth to seal god, that was the plan BUT. Meltier did an oppsie, he killed the god because he went mad.
Why? Bc it was revealed to him that the world is bound to fall into darkness. Why? Because u cannot kill darkness with light magic, that will only strengthen the darkness. So ur only option is to die or run away. But meltier alr killed a shit ton of darkness. Which mean the world is alr doomed becuz they killed everu simgle darkness on the way to sealing the god.
Meltier went mad and went oppsieee killed our god lmaoooo. The god planned to use Meltier n holy sword and the broken world to create a new one. Which ultimately means there's ZERO way of saving the world.
Shane and friends went around on an adventure just to find out this info.
So in the end, shane and friends still gathered together to create a better plan. Turns out, Shane, Meltier, and the holy sword, with the help of the fish and Hamel, can create a better world. They can do what the god offered to do.
They'll still sacrifice this world, Hamel, and everyone else. BUT They'll make a better world wit it. Hamel simulated a better world, fish gathered all the world and turned then into data. Meltier destroyed himself which would create a shit ton of energy to create a new world. And Shane is there to take the role of the god and create the new world.
(Also, meltier only sacrificed himself becuz shane could atleast return to his world if Meltier was the one to die.
In the end, Shane became a god, created a new world, and made the world better. And they lived happily every after the end.
