Kairiki
[It's a choice... not a curse.]
After the original timeline is destroyed and revised for good, Hydro Undergrove lives a double life - part-time cameraman for a local photography studio, part time cosplay event staff, part-time overpowered menace with a past soaked in blood. But his fragile normalcy begins to collapse when another world starts bleeding into his own - a world where every fictional character and impossible place ever dreamed of suddenly exists, vast and overwhelming, larger than Jupiter itself. The system is already deleted, but it will be revealed soon enough.
What should have been a simple vacation and reunion with old friends spirals into something darker. Hydro, already isolating himself, finds that reconnecting isn't easy when you're no longer the same person they remember. Meanwhile, a pack of hitmen and other groups tried to find some thing valuable for their boss, but when Hydro gets in the way, everything became a total chaos: a Malware-glitched of a terrifying figure is interested yet angered against Hydro.
Hydro wields the terrifying ability to summon millions of shadow soldiers and have godly powers, a force so vast it edges on the divine, being even more omnipotent, omnipresent, omnisient, and omniversal. Yet he rejects the very idea of godhood, refusing the labels of hero, villain, or savior. To him, power means nothing if it strips away the fragile threads of normal life he desperately clings to. But when the mysterious figure threatens to consume his identity and become the darkest reflection of himself, Hydro faces the ultimate choice: will he fight to preserve his humanity, or embrace the monster the world already believes him to be?
