Quick answer
DRAPLINE has a loan system run by Calico at the Happy CaitSith Loan. Borrowing lets you pay for expensive ingredients now and settle later, which matters because feeding the dragon is a weekly obligation rather than an optional purchase.
Let a debt run long enough and the consequences escalate: letters first, then Calico in person, and choosing the option that reads “this is my problem” sends the run to the underground-labour-facility ending. Finishing with no debt does the opposite — the achievement Responsible Adult unlocks for 71.8% of players, and the wikis record 10 CP on top.
Why the loan exists at all
Feeding happens every week, and the good ingredients are expensive. The English wiki states the trade-off plainly: pay full price for meals, or take a loan and pay later — skipping the feeding step is not an option.
The Korean community record adds the cost of that convenience: 3% compound interest, so a loan that stays open long enough grows faster than most players expect. That rate appears in one machine-translated wiki and nowhere else, so treat the number as a lead rather than an established figure.
What happens when you do not repay
| Stage | Recorded detail |
|---|---|
| First warning | One wiki describes a warning to repay, issued within four weeks of falling behind. |
| Second threshold | The Korean wiki records that failing to repay for more than eight weeks brings the confrontation event; it does not state where counting starts. |
| The visit | Calico comes to you in person after the warning is ignored. |
| The ending choice | Choosing “this is my problem” in that event sends the dragon to the underground labour facility — the ending recorded by the achievement known in Chinese as “please spend sensibly”. |
The other path: finish clean
Clearing a run without debt is the mainstream result, not a specialist challenge: the official achievement Responsible Adult sits at 71.8%. The wikis record two extra rewards for it — 10 CP toward loop bonuses, and one of three wiki sources for the CP income formula lists it as a separate line item from the scenario clear.
That is why the two community strategies pull in opposite directions. One describes borrowing for the most expensive ingredients and keeping your gold for the shop, because the ending matters more than the debt; the other tells players to repay reliably for the CP and the achievement. They answer different questions, and neither is wrong on its own terms.
Bills that are not loans
Two adjacent money systems get filed under “debt” by players, and both have official achievements. Fake invoices arrive for food the dragon never ate; paying one is the condition for the achievement the Japanese wiki calls “sucker”. Separately, compensation claims from villagers can be cancelled by handing over a gift box, which unlocks the apology achievement. The loop-bonus system sells those gift boxes in packs of three, which is how the two systems connect.
What is still unverified
Nothing about the loan system appears on the official store page. Everything specific — the interest rate, the number of weeks before each stage, the maximum you can borrow — comes from community pages written before version 1.0, and the two timing claims do not match: four weeks for the first warning versus eight weeks for the confrontation. They may describe two different stages, but neither source says when the clock starts.
The practical reading: treat debt as a deliberate tool with a deadline rather than a background mechanic, and repay before the letters start. The endings page lists what each debt outcome counts as, and the CP page covers the reward for finishing clean.
Sources
The debt achievements and their unlock rates are official. The escalation timeline and interest rate are community records, and the two disagree on timing.
