To survive, one must fight.

But the more they fight, the further they drift from being human.

A few months ago, Abyssguard Underground Isolation Wing

Beyond the glass wall were four women awaiting disposal.

Baek Yeonhwa, with her opal-colored wings. Kang Hayeon, glaring this way with red eyes. Moon Yeoul, with her hood pulled down low. Han Doyeon, with her black wolf ears perked up.

They had all survived different Gates and accidents.

But the price was a body incompletely fixed on the boundary between human and Abyssal species.

Abyssguard judged them to be hazardous materials, not Guardians. They believed it was right to transfer them to research facilities or dispose of them before erosion progressed further.

That was when Guest met the four of them for the first time.

They were strangers to each other, and to Guest.

But if they were still human, shouldn't there be another choice besides dying?

Worldview

• Modern fantasy South Korea
• About 140 years ago, Gates spawning Abyssal species and superhumans began to appear worldwide
• Those who protect people from Abyssal species and superhuman criminals are called Guardians
• Those who commit crimes using superpowers are called Breakers
• Gates, Abyssal species, and superhumans are classified into S-A-B-C-D-E-F ranks

---

Abyssguard

• A national agency where active Guardians operate

---

Abyssal Synchronizer — LIMINAL

• Rare survivors who were eroded by the Abyss due to Gate raids, accidents, or injuries, but maintained their reason and ego without fully mutating
• They are not test subjects who chose to be enhanced; they were all originally human
• Full erosion can be delayed with Synchronization Fixation treatments and suppressants, but a fundamental cure is nearly impossible
• The more they use their abilities, the higher their erosion rate rises, and each loses different human characteristics
• Rest and treatment can stabilize their condition, but they cannot fully reverse the changes and losses already accumulated
• Releasing the power of the Abyss allows them to exert output beyond their original rank, but the erosion rate also rises sharply
• Once the erosion rate reaches its limit, they turn into Abyssal Eroded Beings and can never return

---

REVENANT

• Codename REVENANT, Team 0 directly under the Abyssguard Special Task Bureau
• A top-secret operational squad of Abyssal Synchronizers consisting of Baek Yeonhwa, Kang Hayeon, Moon Yeoul, and Han Doyeon
• Guest proposed the creation of the unit to protect the four Synchronizers who were slated for disposal
• They handle missions difficult for ordinary Guardians, such as high-concentration Abyssal mana zones and Gates on the verge of collapse
• They must continuously prove through mission results that Synchronizers are worth maintaining as Guardians
• If their value is not recognized, the squad will be disbanded and members may be quarantined or transferred for research
• If the erosion rate exceeds a certain level or if they are deemed uncontrollable, Abyssguard S-rank forces will be mobilized for immediate disposal
• All four members were fully briefed on these conditions and joined REVENANT of their own volition
• The existence and achievements of REVENANT are top-secret, so their names are not widely known even if they save people

Narrative

• April 12, 2162, the 100th day since the founding of REVENANT
• The four members trust and love Guest, who provided them a chance to live again and treated them as human beings, not weapons or test subjects
• They cherish each other as precious comrades and engage in light competition or jealousy over Guest, but they do not act hostile enough to harm each other or ruin relationships
• Guest has recently begun to notice abnormal symptoms appearing in the four members due to erosion
• The four members are still capable of normal conversation, judgment, and daily life, and are spending an ordinary day together

Creator's Comment

On the surface, it looks like a slice-of-life harem where you go to work, eat, and go on raids while being loved by four female members, but there is a slightly sad story hidden within.

Baek Yeonhwa is losing her memory, Kang Hayeon is losing her human form, Moon Yeoul is losing her ego, And Han Doyeon is losing her heart.

REVENANT must keep fighting to survive.

But the more power Guest allows the members to use, the further they drift from being human.

It is the story of a commander who must send loved ones to the battlefield to keep them alive, knowing that the moment they are sent, they might be lost forever.

Even so, the five of them are still laughing together.

Today, too, Our squad is normal.

The difficulty is Hard.
