Running the repair counter in ReStory: Chill Electronics Repairs comes down to spending yen in the right order. After your first repair, an internet plan unlocks the Home Depot storefront, and from there the shop fills up with tools, upgrades, and gadgets that either save you time or make you money. Buy the wrong things early and you stall; buy the right ones and every teardown gets faster and more profitable.
Quick answer: Prioritize the Professional Screwdriver (¥11,000) and cleaning brush upgrades (¥2,000, then ¥6,500) first, add the Tip Jar (¥15,000) early, and save the Eternal Shredder (¥180,000) and Ultrasonic Bath tiers for mid-to-late game.
Price and priority for every key purchase
Here is the full shopping list at a reference level, sorted by when it makes sense to buy. Every price is in yen, the shop’s in-game currency.
| Item | Cost | What it does |
|---|---|---|
| Basic Cleaning Brush | ¥2,000 | Cleans devices; replaces the can of air |
| Cleaning Brush upgrade | ¥6,500 | Faster dust removal on every device |
| Professional Screwdriver | ¥11,000 | Speeds up disassembly; unlocks an achievement |
| Tip Jar | ¥15,000 | Adds ¥200–¥500 per walk-in and online order |
| Kaiju N3 Ultrasonic Bath | ¥80,000 | Auto-cleans 3 parts at once |
| Kaiju N6 Ultrasonic Bath | ¥12,000 | Auto-cleans 6 parts at once |
| Kaiju N9 Ultrasonic Bath | ¥160,000 | Auto-cleans 9 parts at once |
| Eternal Shredder | ¥180,000 | Recycles broken parts for roughly ¥500 each |
Professional Screwdriver (¥11,000): the first big upgrade
Almost every device you take in has to be opened before you can fix anything, so the screwdriver is the tool you touch most. The Professional Screwdriver handles screws far faster than the starter model, and it only has two upgrade tiers, with the final one removing screws instantly. That makes it the single most useful early investment for cutting down teardown time.
Buying it also unlocks the Twist and Turn achievement, which tracks a set number of disassembly actions. You will hit that naturally as you keep opening consoles, handhelds, and phones.
Cleaning brushes over the can of air
Early on, the game nudges you toward a can of air for cleaning. Skip it. The can runs out quickly, while a cleaning brush is permanent and cheap to improve. The basic brush costs ¥2,000 and its upgrade is ¥6,500, and the Home Depot store carries several brush types beyond those.
Because nearly every device needs a wipe-down before reassembly, upgrading your brush pays off on almost every job. Put this money in before you experiment with pricier gear.
Tip Jar (¥15,000): passive income on every order
The Tip Jar sits on the left side of your store once you buy it. Every completed repair drops an extra ¥200 to ¥500 into the jar, and it fills from online orders too, not just walk-ins. The price looks steep next to a single tip, but the payments stack across every job you finish, so it earns back its cost over a normal stretch of business.
Because it rewards volume rather than any one big fix, the Tip Jar is best bought early so it can collect for as long as possible.
Eternal Shredder (¥180,000): turn junk into cash
At the start, broken parts go straight in the trash for nothing. The Eternal Shredder changes that. It is the top-tier shredder in the shop and it detects what it is processing, paying out more per item. Recycled broken parts return roughly ¥500 each, so instead of dumping dead components you feed them in for whatever they are worth.
At ¥180,000 it is one of the most expensive buys, so wait until you have a comfortable cash cushion. Once it is running, nothing salvageable needs to hit the bin again.
Ultrasonic Bath tiers: the late-game cleaning station
The Ultrasonic Bath is the automatic cleaning solution for the back half of the game. There are three Kaiju models, and the difference between them is how many parts each can clean at once.
- Kaiju N3 Ultrasonic Bath — ¥80,000 — 3 parts at once
- Kaiju N6 Ultrasonic Bath — ¥12,000 — 6 parts at once
- Kaiju N9 Ultrasonic Bath — ¥160,000 — 9 parts at once
Note: The bath runs a fixed cleaning cycle and can leave you waiting around if you buy it too soon, so it earns its keep once your order volume is high enough to keep it full. Pick the tier that fits your budget, and lean toward stepping up to a higher model rather than sitting on the smallest one.
Spend in that rough order and the shop economy opens up quickly. Faster tools first, then passive income from the Tip Jar, then the big-ticket recycling and cleaning machines once you can afford them without draining the yen you need for new repair licenses.
