TSUMIMI TIME Walkthrough: Chapter 1 (Days 1-6)

What does “Chapter 1” mean in a TSUMIMI TIME walkthrough?

Chapter 1 in fan guides means roughly Days 1-6 of the official 15-day loop, ending at the first big deduction (the ghost-town puzzle). The Steam store page and app details describe 15 in-game days, not a chapter-based campaign. Treat “chapters” as a community and FAQ organizing term: the developer’s Official Hints FAQ uses Chapter 1 and Chapter 2 in FAQ21-22, while route walkthroughs map those labels onto day ranges.

Two independent community guide families (Guidexon walkthrough and the Steam guide “Barebone all endings guide”) align on Chapter 1 ≈ Days 1-6, Chapter 2 ≈ Days 7-11, and Chapter 3 ≈ Days 12-15. That three-chapter map is not copied verbatim from the store API; say clearly when you rely on it.

How is each day structured?

Each day follows the official premise: investigate by day (SNS, map, investigation files) and intervene in streams by night (comments, Mega Chats, gifts). Keywords from streams are not the same object as investigation files used in deductions; the FAQ stresses searching keywords, collecting files, then deducing. For controls, saving, and Ver.1.0.1 fast-forward, see /guides/save-and-fast-forward/ and the hub /guides/red-chat-ritual-guide/.

What happens in community Chapter 1 (Days 1-6)?

Day 1 is described by Guidexon as a tutorial stream; its walkthrough and all-endings article share one author, so the Day 1 detail counts as a single source. Guidexon and the Barebone all-endings guide both say a full day of part-time work pays better than a half day plus investigating, which is why many routes work full days early. All of this is community-reported, not a quoted official script.

From Day 2 onward, guides diverge on which Mega Chats are mandatory for the main route. GamePretty publishes detailed Day 2-3 tables; route-focused guides often tell players to skip non-essential chats. Those lists conflict, and no second independent site confirms every GamePretty row. A verified Day 2-3 table is not published on this wiki yet; do not treat any single table as fully verified.

The Chapter 1 arc still has a clear milestone: collecting investigation clues and completing the ghost-town fill-in deduction . Step-by-step blank answers live on /walkthrough/ghost-town-deduction/ (major spoilers, folded). Failing a deduction can lead to a bad ending, and guides disagree on the details; see /endings/ending-8/ and /endings/all-endings/.

What does the official FAQ say for Chapter 1?

FAQ21 in the Official Hints FAQ is the primary official Chapter 1 help. Publicly stated hints include:

• Send the potato gun gift on the wishlist route by Day 4 (FAQ21).
• On Day 5, during the stream tied to the newspaper investigation, a specific Mega Chat helps pin down where the newspaper scene is set.

FAQ21 itself warns that opening the Day 5 hint reveals a gift requirement, a deadline, and a Mega Chat choice. Expand only if you accept that spoiler level:

Official FAQ13 adds an important constraint: wishlist items, Mega Chat options, and investigation files can differ by route. Any walkthrough table may not match your run line-for-line.

Practical tips before you leave Chapter 1

• Money and time: Night Mega Chats and gifts spend funds; daytime searches advance the clock. See /guides/money-and-part-time-job/ for the official part-time job flow and community full-day work tip.
• Save before streams and deductions: Official help recommends saving from the home screen before entering a stream; community guides extend that to saving before the Chapter 1 deduction. Details: /guides/save-and-fast-forward/.
• Do not expect a day-by-day script here: This page is a scope map. Per-day Mega Chat prices in fan tables use community-reported tiers (often shown as 1000-5000 in English guides) and are not documented as official price steps in the FAQ.
