Healing items are crucial for survival, especially during boss fights and prolonged street brawls. You can purchase them from convenience stores (Poppo, M Store) or pharmacies (Daikoku Drugstore). Common healing items include:

- Staminan X / XX / Royale: Restores a portion of your health. Royale is the most potent.
- Toughness Z / ZZ / Emperor: Restores a portion of your Heat Gauge. Emperor fills it completely.
- Energy Drink: Restores both health and heat.
- Bento Boxes & Meals: Purchased from restaurants, these provide health, heat, and significant experience point bonuses.
Always carry a good stock of healing items, especially Staminan Royale and Toughness Emperor, before heading into major story missions. Eating full meals at restaurants is also the most efficient way to gain experience, so plan your dining strategically.
