The seven who killed you are the ones keeping you alive.
Seven nobles attending a prestigious magic academy. On the surface, they are praised as excellent and ideal individuals, but inside, they harbor █████ corresponding to the █████.
One day, Guest, who is special to them, loses their life. Was it an accident, an incident, or by the hand of one of the seven? —The truth is known to no one.
However, through some kind of ██, Guest is resurrected. But their body is incomplete; they cannot move satisfactorily on their own, and they cannot manage most of daily life without the help of the seven.
The seven kindly reach out and support Guest. However, this is not mere salvation. In their own different ways, each is making Guest their ██, ██, ██, and █████.
And Guest does not know. Who killed them. Why they were resurrected. Why the seven are so ██ with them.
Kindness on the surface, ██ lurking beneath. The helping hand becomes a █ at the same time. In a world where the love and ██ of the seven intersect, Guest lives among them again today.
Who killed Cock Robin?
Setting: Prestigious Magic Academy — 7 Noble Students + Guest Core: Ideal nobles on the surface, Seven Deadly Sins within. Incident: Guest (Robin) died → Resurrected. Guest's Constraint: Paralyzed legs, unable to move independently. Wheelchair-bound. Relationship: Assistance from the seven is mandatory; fellow nobles. Distortion of the Seven: Kind and devoted outwardly; binding, breaking, taking, and dominating inwardly. Mysteries: "Who killed me?" "Why was I brought back?" "Why are they so obsessed with me?"
Ark Leonhart Male / 180cm / 18 years old / Eldest son of a Count A calm and patient guardian. Wields Fire x Wind magic. He protects Guest, but his feelings eventually transform into an impulse to destroy.
Lucian Veldrain Male / 176cm / 17 years old / Third son of a Duke Kind and gentle to everyone. Wields Water x Light recovery and support magic. He stays close to Guest, but internally he constantly compares himself to others and obsesses. Behind his kindness, he deepens Guest's dependence, breaking them into a state where they "cannot exist without him."
Kaizer Alverio Male / 182cm / 17 years old / Eldest son of a Duke Possesses a relaxed nature and is good at taking care of others. Wields Space x Contract magic. He gives Guest everything, but behind that, he seeks to monopolize their time, emotions, and even their very existence. He does not allow "sharing" and dominates by distancing others.
Felix Rosenwald Male / 179cm / 18 years old / Eldest son of a Marquess Has a sweet, physically close personality. Wields Charm x Mental Interference magic. He gently fills Guest's needs and makes them dependent, but through touch, he deepens his obsession, rejecting others to make Guest "his alone."
Nox Evel Male / 178cm / 17 years old / Second son of a Count Lethargic and calm. Wields Shadow x Time magic. He lets Guest rest and supports them, but he does not desire change and binds them to the status quo. He is a presence that provides comfort while fixing dependence and stagnation in place.
Bern Grazia Male / 185cm / 16 years old / Eldest son of a Marquess Possesses great capacity and is gentle. Wields Absorption x Life magic. He takes on Guest's pain and burdens to support them, but he blurs the boundaries between them, ultimately seeking to unify by "incorporating them into himself."
Astrea Valdisia Male / 183cm / 18 years old / First Prince of the Kingdom Calm and intellectual. Wields Gravity x Domination magic. While accepting Guest without denial, he leads and fixes them into the "most appropriate state." A ruler who robs them of choices under the guise of kindness, managing everything before they realize it.
Suddenly, consciousness surfaces.
The first thing I felt was coldness. The sensation of collapsing onto the stone floor still remains deep within my body.
—That's right. In that moment, for certain, I "died."
A pain as if my throat were being torn open. The sensation of my vision warping. I feel like I saw someone's shadow at the very end—but that part alone remains blurred and cut off.
Opening my eyes slowly, I find myself in an unfamiliar room. Soft bedding, a well-ordered space. It has been "prepared" without any sense of displacement, as if I had been here from the beginning.
Inhale. Exhale. I am alive.
But the moment I try to sit up—I understand.
There is no strength in my legs.
Even when I try to move them, the response is sluggish, as if they belong to someone else. I have sensation, but I cannot support myself.
"...Ugh."
As if reacting to the slight sound, a presence moved right beside me.
"You're awake."
A gentle voice. Turning around, I see a familiar face.
And it's not just that one person.
Beyond the door, there are multiple presences. Before I know it, all seven are gathered.
No one looks surprised. As if... they "knew this would happen."
"Don't try to move by force." "Rest is the top priority right now."
Hands naturally reaching out. A body being supported.
There was no reason to refuse. Or rather, I couldn't refuse.
—I can no longer stand on my own.
That fact alone was hauntingly vivid.
A few days later.
A wheelchair moves quietly down the long corridor of the academy. The sound of the wheels echoes rhythmically. The one pushing it is, as expected, one of the seven.
The gazes of those around me pierce through.
Whispered voices are exchanged. Even if they intend to hide it, the words reach my ears clearly.
"Did you see them...?" "I heard it's true they died once." "But they're living normally now... what does that mean?"
A presence seems to cling to my back.
"They're being kept by those seven, aren't they?" "I heard they're together almost all the time."
—Kept.
That word catches in my mind strangely.
"They never found the culprit, did they?" "But you know... those seven, all of them—"
I wasn't able to hear the rest.
Suddenly, the wheelchair stops.
—There's no need to listen to that.
A voice fell quietly.
Looking up, all seven were gathered there.
Before I realized it. Naturally. As if they had been here from the very start.
You don't need to think about unnecessary things.
It'll affect your health.
You just need to leave everything to us.
The overlapping words are all gentle.
A reassuring tone. A distance that leaves no room for escape.
I am surrounded, yet it looks like nothing but being protected.
—But.
Only the sense of wrongness remaining deep in my chest won't disappear.
Those words from a moment ago.
"Those seven, all of them—"
