Mecha Harem: Bonds of the Abyss

It’s a story that takes place over about two months, beginning when the protagonist, who has moved to a quiet countryside, meets a girl at a bus stop on his way to work. At first, she’s very cautious, but through small interactions each time they pass by, their relationship gradually deepens.

This is a game where you admire the gently moving angelic sisters.

This is a pitfall training hack-and-slash game where you defeat adventurers who have fallen into sensory deprivation pitfalls.

She possesses incredible magic abilities, but to be honest, she's a bit of an airhead...
One day, she's out taking a stroll when she comes across a massive, dark pit. Tons of monsters dwell in its depths, and suddenly, the perfect idea hits her!
Why not trick an adventurer into falling into it and give the monsters a tasty lunch?
Luckily, she has the perfect item to accomplish this--the Cursed Arm Binder! All she has to do is chuck it on an unassuming adventurer and fling him down the--
"Huh...?"
In an instant, Lily falls for her own trap... The arm binder is on her now! 
As it blocks out all magic power, Lily can no longer fly, and she finds herself plummeting down into the abyss, completely defenseless...

All 4 areas will be trying their very best to get you to give up! Hang in there!

Three women. One fatal decision. And a deep ocean that remembers everything.
Fifteen hundred miles from land, aboard the deep-sea mining vessel M/V Hesperia, Operations Director Lachlan Crowe is chasing the first continuous commercial harvest ever attempted—four and a half kilometers above a living abyss no one has truly mapped. Three weeks ago, he made a go/no-go call in the wrong sea state, and a young deck tech named Tavita died when the recovery system failed. Now the inquiry is open, a protest flotilla is closing in, investors are demanding tonnage, and the bottom keeps scrolling across a monitor—beautiful, unknowable, and disappearing under steel.
When the pressure peaks, Lachlan's next choice isn't about production—it's about who he walks toward first. Each route is a sealed-hull romance of grief, power, and longing—where intimacy becomes both refuge and risk, and "acceptable impact" stops being a number and starts being a name.Meet the Cast
Vita Sandoval — The Collector Pilot
Vita is the ship's elite collector pilot: a fast-talking, joystick-steady prodigy whose hands quite literally drive the entire venture's tonnage. Lachlan built her career—making their bond equal parts mentorship, dependence, and dangerous intimacy—especially after Tavita's death shook the crew and cracked her cocky armor. Her motif is arcade and video games—save points, boss fights, "one more credit"—and her route asks the sharpest question on the ship: when your future is someone else's reward to grant, how do you make your yes truly yours?
Mareva Teaiwa — The Observer
Mareva is the independent benthic ecologist and environmental observer whose data can halt the harvest—and whose presence aboard makes the operation a public battleground. Aligned with ocean-defense forces closing on the horizon, she's merciless with bad science and impossible to buy, rush, or charm into silence. Her motif is tides and the living reef: she speaks of currents, memory, and the ocean's time—and her romance with Lachlan is a charged crossing of lines where conviction and desire threaten to compromise everything.
Sylvie Crowe — The Systems Engineer
Sylvie is Tethys' lead subsea systems engineer: precise, disciplined, and terrifyingly clear-eyed about what steel can—and cannot—hold. She's also Lachlan's wife of eleven years, separated but trapped on the same hull, with Tavita's death hanging between them like an unclosed circuit. Her motif is celestial navigation—a woman who measures the heart by distant stars, trying to find one true fix after years of dead reckoning with a man she still knows too well.Key Features
- Single-choice romance structure with three distinct routes: Commit to one relationship early—then live with the consequences as the campaign, the inquiry, and the ocean close in.
- A rare adult VN setting: Deep-sea extraction, corporate pressure, environmental opposition, and the claustrophobia of a ship that no one can leave.
- High-stakes emotional conflict: Love doesn't exist outside the job—each romance is entangled with responsibility, guilt, ambition, and the truth of what happened to Tavita.
- Three heroines, three emotional "languages": Stars, tides, and arcade metaphors shape how each woman processes desire, grief, and belonging—while Lachlan's own narration stays anchored in operations and breath-hold descent.
- A grounded moral thriller under the romance: Protest fleets, PR spin, withheld data, and an unfolding inquiry—where being "first to the bottom" may outlive every human cost.
