Gift timing calculator: can it still arrive?
The potato gun must reach Tsumimi before the Day 4 stream, and the stun gun before the Day 6 stream. If you are on Day 5 or later, the potato gun can no longer trigger the Day 5 newspaper scene — no keyword, no investigation file, and the chapter deduction loses an option.

The formula, so you can check it
margin = deadline_day − current_day sendable = margin ≥ 0 (a gift sent on the deadline day still counts, as long as it arrives before that stream starts) last_chance = margin = 0 missed = margin < 0 We count in whole days because the game's clock advances in day blocks; there is no partial-day window we could observe.
Assumptions this rests on
- A gift only registers if it is delivered before the same evening's stream begins. This is stated in the official FAQ and we reproduced it in Version 1.0.1 — marked Confirmed.
- Deadline days are Day 4 and Day 6. Both deadlines are Confirmed; the wider gift list in the gift guide is not.
- Buying the item earlier but shipping it late does not help. Owning it is not the same as delivering it.
Where this calculator stops being useful
- Only two gifts have a confirmed deadline. If you are asking about any other wish-list item, this calculator cannot answer, and we will not invent a day for it.
- Whether a specific gift appears in the wish list at all can vary by route. That part is Unverified, so the calculator tells you about timing, not availability.
- Some players report the stun gun not appearing after Day 5. We could not reproduce it, so it stays a report, not a rule.
FAQ
- Can I still send the potato gun on Day 4?
- Yes, if you send it before that evening's stream begins. Day 4 is the last chance; from Day 5 the Day 5 newspaper scene can no longer trigger.
- What happens if I miss the stun gun deadline?
- The Day 7 floor-check option stays unavailable for the rest of that run. You do not get a second chance at it in the same save.
- Does buying the gift early help?
- No. What matters is the delivery timestamp, not the purchase. A gift bought on Day 3 and delivered after the Day 4 stream is treated the same as never buying it.
- Why do only two gifts appear in this calculator?
- Because only two have a deadline we could confirm. Adding guessed dates for the rest would produce a tool that looks complete and is wrong, which is worse than a short one.
- Do missed gifts affect which ending I get?
- They remove options rather than force a branch. Missing both deadlines narrows the deduction choices available at the chapter end, which makes certain endings unreachable in that save.
