How to unlock Rin’s Synergy
Clear the Chapter 1 side mission 異文化交流のススメ (“A Guide to Cultural Exchange”) to unlock Rin’s Synergy. Progress requires the Knowledge human parameter. No specific Knowledge threshold is stated here, so raise Knowledge if the next progression step is unavailable.
What each Rin Synergy rank unlocks
| Rank | Unlock or benefit |
|---|---|
| 1 | Unlocks battle-item crafting. |
| 5 | Adds Chinese-cuisine recipes. |
| 9 | Adds more craftable battle items. |
| 13 | Crafting battle items has a chance to return some materials. |
| 17 | Adds more Chinese-cuisine recipes. |
Rank 13 is the key efficiency breakpoint: returned materials can reduce the resources consumed by battle-item crafting. Ranks 5 and 17 expand the Chinese-cooking recipes, while ranks 1 and 9 broaden access to battle-item crafting.

Which gifts are most efficient?
- For the largest first boost: Latest Digital Camera gives +256, followed by Horror Video at +220 and Latest Electric Toothbrush at +208.
- For repeat gifts: Compare each item’s affection with its in-game yen cost and whether its listed shop is convenient. The guide identifies Black-Frame Glasses, Idol Photocard Set, Mixed Nuts, Kendama, Limited-Edition Keychain, and Assorted Snack Pack as relatively inexpensive repeat options; the camera gives the largest single boost.
- For crafting: Balsam-Dyed item and Jasmine Tea come from the workbench; Jasmine Tea requires simple wrapping ×1 and jasmine ×6.
Version and translation notes
These values and locations are guide-listed game data, not independently confirmed for every live-service patch, region, or language version. Inventories, translations, or affection values may differ as the game changes. Some English gift names above are explanatory translations of Japanese guide labels; use the Japanese item name where an exact match matters.
