Kiryu's growth in Yakuza 6 is tied to five different experience types:
- Strength (Red): Increases attack power.
- Agility (Blue): Improves movement speed and dodge capabilities.
- Spirit (Yellow): Boosts defense and Heat Gauge accumulation.
- Technique (Green): Enhances combo variety and special moves.
- Charm (Purple): Affects social interactions and certain mini-games.
You earn these experience points by fighting, eating at restaurants, completing substories, and engaging in various activities. Once you have enough experience, open the main menu (Options button) and navigate to the 'Skills' section. Here, you can spend your accumulated experience to unlock new abilities, increase your stats, and learn new Heat Actions. Prioritize skills that complement your playstyle, but don't neglect any category entirely, as a balanced Kiryu is a formidable Kiryu.
