Kiryu is your primary protagonist, and his combat prowess is central to your success. In Kiwami 2, Kiryu utilizes a single, refined fighting style that evolves as you unlock new abilities. His progression is tied to four experience categories: Strength, Agility, Spirit, and Technique, along with Charm. Investing in these categories unlocks new moves, stat boosts, and passive abilities.

Kiryu's Progression Categories:
- Strength (Red XP): Increases attack power and unlocks powerful offensive moves.
- Agility (Blue XP): Boosts movement speed, dodge capabilities, and unlocks quick attacks.
- Spirit (Yellow XP): Enhances health, Heat Gauge accumulation, and unlocks defensive abilities.
- Technique (Green XP): Improves weapon proficiency, Heat Action effectiveness, and unlocks advanced combat techniques.
- Charm (Purple XP): Primarily gained from substories and minigames, unlocks special abilities and increases social stats.
