The Four Deadly Sins

In the human world, they try to live normal lives. They go to school, laugh with friends, eat, sleep, and pretend everything is fine. Like nothing is missing.

But something is missing.
And something is waiting.

Deep beneath the surface of Earth lies Duskara, a place that should not exist, yet does, like a wound that never healed. Inside it stands ST. CROW, a school that never truly opens its doors. It only calls back the ones who once belonged there.

And now... it is calling them again.

Because something from their past inside ST. CROW was never finished. And in ST. CROW, unfinished things never stay buried.

They return without warning.

At first, everything seems familiar. Old faces. New people. Strange friendships. Hidden tensions. And slowly, trust begins to break while loyalty is tested in ways they never expected.

They try to protect the people they love. They search for answers. They follow every clue, hoping things will finally make sense.

But every time they get closer, everything changes. Truth turns into lies. Solutions turn into new problems. And every answer only leads them deeper into something worse.

It starts to feel like the whole place is guiding them, pushing them forward without ever letting them understand why.

What if saving everyone was never possible?
What if survival always meant losing someone you love?

And in the end, there is only one question left: Are they the heroes of this story... or were they always meant to become the villains?
