A Simple Life with My Unobtrusive Sister: 100% Unlockables Guide

This is my 100% unlockables file for A Simple Life with My Unobtrusive Sister — life sim upstairs, roguelite dungeon downstairs, and a video archive that eats evenings if you let it. I soft-locked nothing permanent except patience; your mileage may vary.

Soft cheats without breaking story: Cheat codes and admin commands. RNG events and hearts: Relationship and event routes. After credits: Post-game and hidden videos. Bugs and saves: Bugs, controls, and save migration.

What 100% means here

Relationship tracks pushed far enough for scene variants and epilogues.
Outfit / item chains (T‑shirt, gacha pink stuff, van purchases) done or deliberately RNG‑rolled with saves.
Dungeon milestones for Philosopher’s Stone healing and self upgrades.
Archive / database clips surfaced (post‑game admin helps).
Achievements tied to admin commands if you want the last stragglers.

Not a speedrun — a checklist sim.

Heart system (two tracks)

Track	Meaning	How I raised it
Red hearts	Trust / affection	Chat, gifts, games together, good daily choices, cooking, head pats at home
Purple hearts	Intimacy / lust	Unlocks after high red; nighttime teasing and chest interactions

Scene gates: extra variants around 5–6 and 7 purple once red is solid. Trust first, then push purple when routes ask for it.

Opening tip from my run: when she wakes you, hug — raises her desire baseline and keeps later intimacy routes open. Many prompts are timed; slow replies cost hearts.

Inventory and power (do early)

Unlock	Effect
Neko Plush Suit	Equip once: +10 weapon slots, +20 equipment slots — stays unlocked after unequipping; also filters junk pickups
Small Mana Gel	Permanent bag growth; cost ramps; from ores and Trash Bin (discard gear in main area to spawn bin)
Philosopher’s Stone Fragment	Boss drops → two heals for sister first (extends bedtime / story); then use extras on yourself for stacking stat + capacity bumps

Economy: find Aki with Sushi Pudding; gift salmon to lower Konpeito prices over time instead of buying outright.

Neko Plush Suit — one equip permanently expands your bag

Detail and early cash: see Early money below and relationship guide for cooking.

Dungeon rhythm

Bosses respawn every 7 in‑game days, or instantly with Tarot The World. They scale — plan farms.
Ruins Floor 3 boss → Red Marrow Fluid → sister healing path and morning interactions (chance‑based).
Abyss boss → first Philosopher’s Stone Fragment → melt through red door, mix with milk, start recovery so she stays up later.
Bunny girl boss (ruined forest) → next heal tier for longer nights.
After two sister heals, farm fragments for self stats before greed‑pushing difficulty.

Abyss boss — first Philosopher's Stone Fragment milestone

Bomb fishing (early): throw bombs in the river before the dungeon entrance for salmon — not infinite, but reliable early food/trade.

Exploration cash: smash pots/flowers; 5,000 coins behind an old shack in one early area.

Cooking and promises

First dungeon death → dream unlock to ask her to cook.
3× meat (mixed meats OK) → Meat Cuisine promise route → Maiden’s Smile (big affection boost). Early meal talk: pick Fine toward steak, then the promise.
Other starters: 1 apple + 2 slime mucus; 3 mushrooms (any type).

Comfort loop: lightly disturb her while she’s gaming, then 2–3 comforting actions — can roll new promises. Save first; don’t spam.

Full event checklist: Relationship and event routes.

Outfit and hot‑day chain (summary)

Find/buy T‑shirt, gift it.
On a very hot day, come home early — do not use Star Gate.
T‑shirt raises chance hot‑day scenes appear. Atsu Bozu item can force a scorching next day if you have it.

Bathroom RNG scene: buy “pink stuff” from suspicious vendor gacha (~5,000 coins/roll), combine with milk during bathroom interaction — save scum friendly. See gacha screenshot.

Night scenes and shop items

Philosopher’s Stone heals (×2) extend how late she stays up.
Some late scenes (horror movie, adult video) need purchases from cat girl’s van via Chariot card summon + purple thresholds — leaf details.

World pickups (quick)

Secret	Where / what
Rubber duck	Right shore Adventurer’s Street‑2 → fun home interaction
Axe	Left of house → Hardwood Stick → early cash

Search terms and admin database: Post-game and hidden videos.

Post‑game (after credits)

Chat: ADMIN_UNLOCK — admin mode + More Than a Guest achievement.
Chat: ADMIN_RANDOM — random video + Lucky Dip.
Use admin search to mop clips (sick, husband, quoted "yes", "beach", etc.).
Endless bosses — keep farming; fragments after sister heals go to you.
Database checker / BLANK search to verify missing entries.

Save habit

Rotate saves before bosses, before daily cycles that might trigger events, and before promise experiments. Migrate www/save when updating builds — bugs and saves.
