Human Farm Investigation Day-by-Day Walkthrough

How this walkthrough differs

Story Overview summarizes plot beats. Day-by-Day focuses on repeatable daily structure — what to check each morning, how to split time between underground farm labor and city investigation, and when to save before irreversible evenings.

Human Farm : Investigation : (Steam 3953160, launch August 7, 2026, とっくり海月 / 072 Project) runs on a calendar with thirty-four story events and five or more endings. Missing one evening appointment often costs a scene, not just flavor text.

Demo players: only Day 1 overlaps — Demo Day 1 — then restart on a full save.

Universal daily template

Use this skeleton until you memorize branch-specific exceptions:

1. Morning — read messages from Tsubaki, Maria, or Rui; note quest log icons
2. Farm block — minimum chores for Boss, Aina, Karen — Underground Farm
3. City block (if open) — quests, Alice performances, evidence items — City Quests
4. Evening — scene tiles underground or in city venues — How to Unlock Scenes
5. Debrief / sleep — confirm no yellow markers remain; advance calendar

Enable run mode before day two — Settings and Run Mode. Use arrow keys and Z/Enter at doors; mouse will not open doors — Keyboard Controls.

Farm vs city priorities

Investigation fails when players treat city days as optional.

Signal	Lean farm first	Lean city first
Boss assigned urgent chore	Yes	—
Suspicion rising	Yes	—
Tsubaki deadline tonight	—	Yes
Alice performance icon	Partial farm then city	After minimum farm
Item handoff expires at sleep	Whichever log marks urgent	Whichever log marks urgent

When both farm and city icons appear, complete farm minimum (enough to avoid suspicion spike) before leaving topside — Investigation Mechanics and Beginner Tips.

Alice chains punish skipped performance nights — Alice. Karen dorm scenes punish skipped farm evenings. Consult Scene Checklist when conflicts arise.

Save habits

Calendar RPGs live or die on saves:

• Create labeled slots per day (D05-pre-city, D12-pre-raid)
• Never quick-save over your only pre-branch file
• Save before handler meetings at Cafe Hub
• Keep one rollback slot three days behind current progress during first playthrough

Scene gallery unlocker and action cheats do not satisfy ending flags — save legit progress separately — Cheats and Unlockers.

Early days (Days 1–3)

Day 1 — Tutorial infiltration, first farm shift, control learning. Demo ends here on app 4629570.

Day 2–3 — Handlers introduce city travel. Establish run mode and keyboard door habit. First optional evening scenes appear — prioritize quest log over map exploration.

Spoiler-light beats: Story Overview first section.

Mid campaign (Days 4–10)

Investigation meters and suspicion interact heavily:

• Neglect Tsubaki evidence → incomplete investigation endings
• Neglect Boss → blown cover routes — Ending Routes
• Stack Rui errands with Alice nights when calendar allows

Item pickups may be one-time — sweep visible objects before sleep — Items.

Patch note: if events misfire on unpatched launch builds, apply RP26071196 — Official Patch and Version History.

Late campaign (pre-raid window)

Raid eligibility appears in UI when investigation thresholds satisfy Tsubaki — exact wording varies by build.

Before accepting raid prompts:

• Cross True Ending Checklist if targeting best outcome
• Confirm Alice and handler branches not mid-chain
• Save dedicated pre-raid slot

Recall-room sequences carry intense content — warning text updated in RP26071196 (26/08/07) — Content Warnings.

Endings and scene links

Daily choices accumulate into five or more endings:

• Investigation completeness
• Cover status
• Handler and farm relationship emphasis

Gallery completion ≠ ending completion. Track endings on Ending Tracker and philosophy on How to Get Endings.

Second playthrough: use Ending Routes for branch-focused day skipping.

Patch and version discipline

Note Steam build ID when comparing day notes from forums — Version History. Steam Verify integrity may remove patch files — reapply RP26071196 — Common Issues.

Introductory offer ending ~Aug 21 does not affect walkthrough logic — Should You Buy.
