Those Damned Space Rocks Saved My World (Completed)

It's back!
Life is back to normal for Saiki, Killua, Ban and Gowther. Or so they thought. Another problem has reared its ugly head. This time, in Saiki's world.
Since Saiki returned to his world, he's noticed something slightly off. He ignored it because he had just been isekai'd, nothing was normal. But, when the rise of a rather destructive group threatens to destroy his perfectly average life, Saiki decides to take action. Is there anything he can do? Not by himself there isn't. Yet again, the four of them are called to action, but this time, to save Saiki's world.

Sequel to This is Why I Don't Touch Weird Space Rocks. You should probably read that first.

I own nothing. Nada. Not the pictures, not the characters... well I do own the villains, but other than that, N O T H I N G.
