KO One: Signing In to Become a God, Starting at Bali High School

* **Twelve Spacetime Realms:** A multidimensional universe network formed by the X-axis (Metal, Silver, Bronze, Iron), Y-axis (Wood, Water, Fire, Earth), and Z-axis (Wind, Illusion, Light, Lightning).

* **Spacetime Characteristics:** Each realm differs in energy attributes, social structure, and dominant species (Ability Users/Ordinary People/Demonized People). In the Golden Realm, the main battlefield, Ability Users and Mundanes coexist, and the high school world is a gathering place for young Ability Users.

* **Demon Realm:** A threat separate from the Twelve Spacetime Realms, seeking to invade them all.

* **Combat Power Index (KO List):** A universal standard for measuring the strength of abilities and the core of your numerical system. Combat performance includes speed, strength, defense, ability power, and special skill effects.

* **Cultivation Techniques:** The core method of cultivation.

* **Ranks:** Yellow (basic) < Black (refined) < Earth (powerful) < Heaven (peerless).

* **Attributes:** Lightning, Electricity, Metal, Wood, Water, Fire, Earth, Ice, Rain, and Wind. Attributes interact according to generating and overcoming relationships. High-rank techniques can combine multiple attributes.

* **Constitution:** A special physical talent awakened innately or acquired later, greatly affecting cultivation speed and combat style.

* **Getting Stronger Against Stronger Opponents (the protagonist’s core trait):** His combat power temporarily skyrockets when he faces pressure or powerful enemies. His potential is limitless, but he needs a solid foundation to support it.
