Both Kiryu and Majima upgrade their abilities by spending yen. Each fighting style has its own upgrade tree, allowing you to unlock new moves, increase stats, and improve Heat Actions. Additionally, various trainers scattered throughout Kamurocho and Sotenbori can teach you powerful secret techniques for a fee. Investing in these upgrades is crucial for tackling tougher enemies and bosses.

- Health & Heat: Prioritize increasing your maximum health and Heat Gauge capacity.
- Attack & Defense: Boost your damage output and reduce incoming damage.
- New Moves: Unlock powerful combos and special attacks.
- Trainers: Seek out specific NPCs (e.g., Bacchus for Kiryu, Fei Hu for Majima) to learn advanced techniques.
- Completion Bonuses: Fully upgrading a style often grants a bonus.
