Keep hunger above empty to preserve natural healing, use meals for temporary stats, and build Koo rapport at the Cleanse Walker.
Your first survival priority is not hoarding every meal. Keep the hunger gauge from reaching empty, because Emma and Koo's natural healing depends on it. Then use the Cleanse Walker to turn gathered ingredients, crops, and time with Koo into stronger preparation for the next area.
The early preparation route
- Rest at the first available camp. Learn what restores and what repopulates before pushing deeper. Nearby enemies also give you a low-cost place to practice just guards.
- Check hunger before leaving safety. If the gauge is empty, natural recovery stops. Eat enough to restore the healing condition rather than waiting until a difficult fight exposes the problem.
- Read the meal effect. Food can improve HP, Attack, or Defense in addition to feeding the pair. Choose a bonus that matches the next task instead of consuming meals in random order.
- Bring ingredients back to Kagura. Her cooking options improve as you engage with her and return recipes. This turns field gathering into a longer-term supply system.
- Use the Cleanse Walker's production. Crops and eggs expand the ingredient pool. Seedlings have different harvest times, so plant before leaving rather than after you already need the result.
- Interact with Koo. Petting, treats, and cleaning increase rapport. Rapport is not only cosmetic; it can expand the number of skill slots available to him.
- Spend a short practice cycle on combat. A fed, prepared pair still needs Fluorescence Points. Use a camp-adjacent enemy to link one just guard to one Koo command before moving on.
What to carry into a new area
Think in roles rather than a universal item list: one immediate recovery option, enough food to keep hunger active, a meal whose bonus fits the expected fight, and the currently useful ranged or sword tools. The game includes multiple weapons and skill trees, but a “best” loadout changes with unlocks and enemy behavior.
Koo also helps outside direct combat. The official hands-on account describes him guiding Emma toward objectives, reacting to points of interest, and bringing back items. Pay attention to those behaviors instead of treating him as a damage button that appears only in the command menu.
Three mistakes this loop prevents
- Empty hunger during exploration: natural healing disappears when you most need it.
- Saving every strong meal forever: stat bonuses have value when they help clear the next hard segment.
- Ignoring rapport: fewer Koo skill slots limit the tactical half of the combat system.
For the timing and resource side of combat, use parry and Koo combat. If menus or camera behavior differ from an older video, verify the current version.

QUICK ANSWERS
Questions players ask next
Why is Emma not healing naturally?
Check the hunger gauge. The official full-game account says Emma and Koo naturally heal only while hunger is not empty.
What does food do?
Food supports the hunger requirement and can add temporary bonuses such as HP, Attack, or Defense, depending on the meal.
How do I improve Koo?
Increase rapport through interactions such as petting, treats, and cleaning at the Cleanse Walker; higher rapport expands his skill slots.
