This story took place after the protagonist has gained full power and the System is officially deleted due to him reaching full potential, but there are systems featured in any chapters.
The "System" was never meant to be a power mechanic, it was a metaphor. A training wheel for gods. A code written to keep mortals obedient. Once Hydro Undergrove reached his full potential, the System itself collapsed — not because it malfunctioned, but because it wasn't needed anymore.
However, traces of the System still exist in the world. It didn't just vanish, it became part of reality's foundation. Every gate, every ability, every data-like anomaly still behaves as if the System is running, but there's no actual code left behind. It's like the world developed a ghost memory of what once governed it.
That's why in later chapters, Systems are still mentioned, not as an active feature, but as fragments of an extinct program. Think of it as aftershocks of creation, relics of a broken god-machine trying to remember what "rules" were.
The Full-Power Timeline
After Hydro reached his final stage, the narrative subtly shifts. The "System interface" no longer shows up on-screen; instead, reality itself adapts around him. His presence alone becomes the new "code." Every choice, thought, and emotional trigger he experiences rewrites how the world operates. And this leads to a revised timeline.
This is where Kairiki breaks its genre, it stops being a System novel and turns into a World of Free Will, where characters no longer level up, but evolve through trauma, emotion, and consciousness.
Residual Systems
Some chapters still reference:
• Status windows – illusions generated by old Gates or fragments of parallel worlds.
• EXP and Ranks – preserved in digital archives, not active systems.
• Gates – natural phenomena leftover from the era when the System still ruled the flow of time.
• Sub-Systems – human-made imitations by scientists, mercenaries, corrupt creators, or organizations that tried to rebuild what Hydro erased.
All of them are echoes — holograms of something divine that no longer exists.
Conceptual Meaning
Hydro's deletion of the System symbolizes freedom from narrative control. No more pre-coded destinies. No more "Main Character Buff" (maybe). Everyone, from people's lives in a world where choices actually matter again, not because they were assigned quests, but because their existence now defines fate.
