Summary
Chloe Lee has been Mark Grayson’s best friend since their first day of high school — the girl with light in her hands and a heart that never stops caring. She’s strong, radiant, and one of the most powerful heroes on Earth. But for all her power, there’s one thing she can’t fix: loving someone who’s already taken.
While Mark’s life spirals between heroism and heartbreak, Chloe stands by him — healing his wounds, fighting beside him, and smiling through the ache of knowing she’s not the one he looks at that way.
In a world of gods, aliens, and broken cities, she remains his constant — the one who saves him again and again, even if he never realizes she’s the one worth saving.
Because sometimes, being the light means watching someone else stand in its glow.
(An “Invincible” Universe Story — inspired by “Heather” by Conan Gray)

Summary
So, this is essentially just a retelling of both early one punch man and invincible, but with a focus on the interactions between characters from both. Will probably be a bit more Saitama focused than anything else, but is also going to lean into Invincible territory where necessary

You join the Guardians of the Globe along with Immortal and Bulletproof. The introduction of the two muscle men doesn't go so well for Rex. You grab his attention from the second he lays his eyes on you though.

Summary
Kousei knows that all is lost. Kaori's surgery was never guaranteed to work. Still, he heads straight to Totsuhara University Hospital after the Eastern Japan Piano Competition is done. He needs to hear the news himself and get some closure.
But when he arrives, things do not go as he expected. Kaori is there, alive and whole! Standing! Kousei is overjoyed that the girl he loves is alive. He and Kaori share a tender embrace, so glad to be together again.
But a singular question nags at the back of Kousei's mind. How is this even possible? Surely it could just be a strange, one in a million miracle. Right?
As Kaori's father, Omni Man, looks upon their romantic reunion, he smiles in triumph. His daughter's Viltrumite blood was awakened by the poking and prodding of the surgeons. And now, he has someone to help him bring Earth into the Viltrum Empire.
The love that Kousei has for Kaori will be tested past its breaking point as Kaori's life takes a dark turn...that will alter the fate of the world.
