Sex, Secrets & Used Tech — Unboxing & Full Walkthrough: Repair Minigames, 12 Heroine Routes, and Every Safe Code

Hey, conductor SON is back! This time we're looking at an adult exploration / raising sim set around running a used-electronics repair shop. You play the owner of a second-hand electronics store: by day you fix phones, PCs and tablets for customers, but one repair at a time you start glimpsing the secrets hidden inside their devices — and get pulled into the city's underside. The game is wide-open, with 82 quests counting side content, and a cast that runs from the girl next door to a doctor, a cop, a teacher and a mysterious succubus. Great for players who enjoy slow exploration and collecting story.

1. Features

• Intuitive UI — quest hints and character relationships are all on the dashboard.
• Hakoniwa-style city exploration: different characters and events appear at different places and times of day.
• The core loop is a "repair minigame" — different devices play out as different minigame types.
• H-scenes use both Spine animation and a large set of static CG variations; everything is logged into the Memories gallery for replay. The Spine jiggle is, uh, intense.
• Lots of content: 82 quests including side stories, and every heroine has her own story line and affinity system.

2. Story Background

The setting is a city whose public order keeps sliding. Mayor Veronica broadcasts daily, urging citizens to download the city's "Peace & Safety APP." It sounds benevolent, but that overly eager tone always feels a little off.

And you are just the owner of one used-electronics shop in town. Life is ordinary — until a girl named Ivy walks in with a broken phone, and everything goes off the rails. You realize every phone and PC you fix hides a customer's secret, and those secrets slowly weave a net leading all the way to the mayor.

3. Goals

On the surface, your goal is to run the shop well and fix customers' devices. But play on and the real spine emerges: through repairs and exploration you push the main story, pursue each heroine, dig up the truth beneath the city, and finally confront the mayor behind it all.

Because the game is highly free-form, "being in the right place at the right time" is the single most important thing throughout. There are also quick time-skips and a magic weekday time-jump — use them well!

4. Gameplay Flow

The game runs on a "location × time slot" system. A day splits into morning, afternoon and night; every action (repair, explore, move) advances time. When stamina runs out or you want the next day, go home and sleep. (Note: sleeping is night-only — if it's too early you must skip a slot first.)

A typical daily loop: open the shop and take customers, fix devices, earn money while advancing the main story for quest data, take your clues to the matching location to push side or main quests, and unlock new districts and characters. As the main story progresses the city opens more areas, and new areas almost always bring new heroine routes — so revisit places often.

5. UI & Core Gameplay

Repair Minigames (the signature loop)

Taking a customer's device starts a repair minigame. Depending on the device and request, you'll play five types: "Teardown" (disassemble and restore parts), "Noise Cleanup" (clear screen static), "Qix-style territory capture," "Match-up" (pairing elimination), and "Audio Restoration." Every request clearly lists its reward and stamina cost; finishing a story-type repair also hands you the data or evidence from that phone, which is key to advancing side routes. If you read my earlier piece on Agent Saku's Secret Operation this will feel familiar — yes, this game is also by 78Games.

DIY builders will smile at the PC-assembly part: these days an SSD really can end up blocked by the GPU, so the order matters — get it wrong in real life and it's a meltdown.

If the minigames feel too slow, Roxy later sells an "Auto-Repair Arm" that auto-clears repairs — a serious time-and-money saver.

Stamina & Money

Stamina is the most important resource — almost every action consumes it, recovered by sleeping or items. Money buys items and pushes certain paid story beats. Always keep a little stamina and cash in reserve so you don't get stuck right before a key event. Repairs each take one action slot, but sleeping late at night can restore up to 100 stamina (after completing all of Miu's lab recovery upgrades).

Adult Scenes & Gallery

H-scenes combine Spine animation with a large set of static CG variations, all auto-registered into the gallery's Gallery and Events tabs after clearing. Story-type repairs often unlock the matching CG right after completion.

Cast & Route Entry Points

Here are the main heroines and where to start their routes. Actual spawn locations and times follow the in-game state — if you're stuck, try a few different time slots:

▼ Jump to character

IvyMayaRoxyMiu (Doctor)Kathy (Police)Clara (Teacher)Nephra (Succubus)Irene (OL)Veronica (Mayor)EmilyNiraMira

Ivy

◎ Where & When

Appears at the cafe on Wednesday afternoons.

★ Route Entry

The first girl you meet; the main story is tied to her phone repair request. Build affinity far enough and her apartment opens up.

Maya

◎ Where & When

At the station front every morning and afternoon; when free at night she waits in the shop like a puppy (requires the park puppy-training event and buying the cosplay set in advance). Loves partying at the bar on Wed / Sat / Sun.

★ Route Entry

A justice-driven policewoman. In the mid-to-late game you pick up her dropped phone at the station — don't miss that CG.

Roxy

◎ Where & When

Trades only if you hold a "lewd ticket," and seems to sell to the shop owner alone.

★ Route Entry

The mysterious vendor by the stairs who sells spy gear and repair tools — also a key main-story ally.

Miu (Doctor)

◎ Where & When

Consultation hours Tue & Fri in Ward A; aside from weekends, when free she's in the lab.

★ Route Entry

Starts from the park's find-the-cat / feed-the-cat event; clearing it opens the hospital and her route.

Kathy (Police)

◎ Where & When

In the afternoon and late at night she sleeps in the security break room.

★ Route Entry

Appears at City Hall in the afternoon / late night. Break a PC first, then get the slacking-off evidence on repair; the key duplicator is needed mid-route.

Clara (Teacher)

◎ Where & When

Collects donations inside the station on Fri / Sat / Sun mornings and afternoons; cleans the park on Mon / Tue / Wed mornings and afternoons; hosts an orgy party at the park late at night on Mon / Tue / Wed.

★ Route Entry

Save up to make a donation first, then join the cleanup event to get clues and a bug — that unlocks her mysterious "club activity" 😀

Nephra (Succubus)

◎ Where & When

Works part-time at the bar in the evening and late at night.

★ Route Entry

Shows up after the PUB opens. Top up your HP and prep items before the showdown — opening the event costs 60 stamina.

Irene (OL)

◎ Where & When

In Ward A at the hospital on Wed & Sat mornings and afternoons; on idle weekdays she takes out trash at the station front; late at night on Mon and Thu she turns exhibitionist, relieving stress in front of the station.

★ Route Entry

A late-game character at the hospital. Break her phone at the station first, get the cheating evidence on repair to advance; investigate the station flasher's camera.

Veronica (Mayor)

◎ Where & When

You need the code first to reach her office via the elevator.

★ Route Entry

The main story's final boss — the whole campaign builds toward facing her. SON's favorite onee-san, no doubt!

Emily

◎ Where & When

Plays with cats at the park on weekday afternoons; enjoys watching her husband's "atonement" at the park late at night.

★ Route Entry

The married woman — this game's key NTR target. Show her the evidence of her husband's affair!

Nira

◎ Where & When

You can rename her by giving her cake. She seems to appear in all time slots except night. Important note: NO lewd stuff!!

★ Route Entry

A bonus route: bring the signature strawberry roll cake as a gift to rename her. Later, Ivy's TV-repair event takes you to the spirit-world hospital on a different timeline.

Mira

◎ Where & When

Interns at City Hall on Sat & Sun; you can meet her at the bar in the evening and late at night.

★ Route Entry

The girl at the bar — the legendary lewd streamer "Honey Milk." Pick up her phone and don't give it back to trigger her side route.

Making Money (repair jobs)

Money mostly comes from repair requests. The table below lists the reward and stamina for each repeatable "general request," plus the "reward ÷ stamina" efficiency — handy if you're grinding cash:

My advice: when you have stamina, prioritize "PC Repair" — 1500 net per job, best value. If stamina is tight or you need quick cash, take the "Noise Cleanup" series. Advanced Qix pays well but is both stamina-heavy and hard, so it's not worth it for pure money. Pairing it with Roxy's Auto-Repair Arm saves a lot of time.

Roxy's Items (stairwell vendor)

Roxy's stall is the most important item source in the game; almost everything she sells ties into the main and side routes. The three "Auto-Repair Arms" and the two "Decoder / Tuner" lines are near-mandatory:

Other Shops & Items

Suggested buy order: get all of the hospital's "Stamina Boost" upgrades first (stamina really is that important), then Roxy's Auto-Repair Arms plus the decoder and tuner; late game you can basically skip the minigames.

Main-Quest Requirements (key costs)

The main story and a few big side routes hit money walls directly, so saving up first makes things much smoother:

• PUB staff pass: costs 5000, obtained after resolving the bar's women's-restroom event (your ticket into the restroom and to investigate the succubus). After the event the owner gives you a batch of liquor as a reward, used later in the succubus story.
• Succubus sap: costs 6000, a key pre-ending item.
• Teacher route: triggers after donating 2000 three times.

Main Story Flow (with prerequisites)

The main story is a linear investigation. Below are the chapter beats in order, with "what to finish before advancing" (experience the actual scenes yourself):

1. Opening & meeting Ivy: fix Ivy's phone (the repair tutorial). Afterward you see the secret photos on her phone, and the main story officially begins.
2. Find Roxy: Ivy sends you to Roxy, the black-market vendor by the stairs. The station opens here. After taking the next day's phone request, a "watched for three days" countdown triggers — just keep running the shop.
3. The cafe at night: advance to late night and Ivy takes you outside the cafe to prep an infiltration.
4. Infiltrate the cafe, get the drugs: after sneaking in with Ivy you must crack the safe — first find numbered objects in the shop (the 9 on the vase, the 3 on the banana picture, the 5 on the chili jar…) to assemble the code. Open it for the "drug coffee pack," then make a key choice: who to hand the drugs to (see the branch below). City Hall opens afterward.
5. Bar opens: unlocks two side routes — the succubus (costs 60 stamina + liquor) and lewd streamer Mira (help find her phone, crack the images hidden inside).
6. City Hall speech & bug setup: you learn the mayor will speak at City Hall, with a three-day prep countdown. Buy bugs and gear from Roxy, plant the bug, and wait late at night for the mayor's bugged message.
7. The park at night: following the message clue, go to the park late at night to meet the mayor and trigger the threat scene.
8. Crack three cameras: you must crack the cameras at City Hall, the hospital and the station.
9. Two parallel lines: split into "hand it to Maya" and "tail the mayor / the restroom party" running in parallel.
10. Final-battle prep: in order — talk to Roxy → get the "sap" from the succubus (needs 6000) → see the doctor → save up enough money → fix the doctor's PC → gather the items → craft → final prep, then face the mayor.

Drug Event Branch (the Ch. 4–5 choice)

After opening the safe and getting the drug coffee pack, the game asks whether to hand it to Roxy or Maya:

• Hand to Roxy (black-market cash): she haggles over the buy price and, counting goods value, recon fee, infiltration fee and travel, pays you a five-figure sum (12000). Recommended.
• Hand to Maya (cop story): at first she mistakes you for "illegal drug possession + bribing an officer" and moves to arrest you; after a scuffle and your explanation she switches to helping you investigate. For a money head-start the cash option is more practical; I felt the later story isn't affected.

All Puzzle Codes

Hidden Easter Egg: the spirit hospital's mysterious note

If you click the note on the floor in the spirit-world hospital, a string of baffling code pops up — it's actually hex encoding, and here's how it cracks:

① The hex on the note30 39 36 37 32 33 34 70 70 61 6d 61 65 74 73

Endings

The game has two main endings: the normal ending (clear the main story, take down the mayor and turn her into a sow) and a BAD END (citizens mass-hypnotized by the APP). All CGs collected during play are logged to the gallery. If you want to collect every CG yourself, keep a save before major branches so you can go back for what you missed. You can also open all CGs via Nira at the spirit-world hospital — very considerate! The spirit hospital also has two illustrations not in the gallery, so remember to talk to the invisible man!

7. Impressions

I cleared the game in one 6-hour sitting right after getting it. Ever since I first saw it at an expo, I'd been waiting for the release news — and it finally came, TAT.

The art and gameplay are both genuinely high quality, and the whole story line is well rounded — it takes "fixing phones" to a whole new level (yep, fixing your way straight into trouble). A full 12 romanceable heroines is fan service galore, and on top of the usual CG variations there's a huge amount of animated artwork. The story beats all connect back and forth, so just following the main line keeps things moving smoothly; if you can't find a quest or don't know what to do, just check the quest panel.

This time the main-and-side quest count hits 82 — seriously thick — and despite the big cast the art volume doesn't slack one bit. The one time I couldn't figure out how to trigger a quest, I'd already played to day 66 with no new quest showing up, before realizing the main story advances when Ivy comes to the shop herself on Monday morning. I panicked thinking I'd hit a bug, then frantically skipped time around the map and — ah — it suddenly resolved (ˊwˋ)y=~

Each heroine appears on fixed weekdays and time slots. The big map does mark where everyone is, but sometimes you just forget which day they show up. Looking back, I spent a lot of the late game time-jumping on the world map — if I'd checked the character panel more, I could probably have played faster.

My personal favorite is that sneaky, covert feeling. As a former "tool guy" myself, flashing ROMs, building PCs and recovering data are all must-have skills for a college nerd — there was real déjà vu, and this kind of hacker-sim vibe is honestly addictive. The same team's earlier title Agent Saku's Secret Operation was actually my first taste of this minigame genre, and this time you also get to tear down and build PCs and fix phones and tablets — so cool. The overall experience is well above the bar; SONY genuinely recommends it to everyone.

Bonus Gallery

A costume crossover with Succubus Heir! It caught me off guard — that title is on sale on Steam too.
