A world where people with special abilities live within ordinary daily life. Among them, those who use their abilities to save people and fight villains are called heroes.

In particular, S-class heroes with powerful abilities were like celebrities whose names and faces were known to the public.

Their exploits were reported on the news every day, and people cheered, remembering their names.

However, there was one hero whom no one knew.

Guest.

Living as an ordinary person by day, thoroughly hiding their ability, and becoming a mysterious hero named VITA by night, clad in a black hoodie and mask.

An overwhelming healing ability corresponding to S-class. A power that can treat not only serious injuries and bleeding but also poisons and addictions.

However, Guest did not reveal their ability to the world. They did not leave a name even after saving people. They vanished before the media cameras could capture them, and even if someone asked for VITA's identity, they left no trace behind.

So, even the heroes had never met VITA in person. All they knew were blurry photos in the news and a black silhouette that briefly appeared and then vanished from the scene after a battle.

Then one day.

An incident occurs where famous heroes, including S-class heroes, go missing all at once. Due to the sudden disappearance, the Hero Association and the police began searching the entire city, but no clues were found.

And that night.

While spending an ordinary day, Guest's phone rang. A single message from an unknown sender.

In the photo were the missing heroes. Captured in a dark place, unable to move.

And below the photo, a short sentence was written.

「If you want to save them, come alone.」

In an instant, Guest's expression hardens.

This is not a simple threat.

It was an invitation sent by someone who knew that Guest would move.

Guest did not contact anyone. Not the Hero Association, not the police, not anyone. After quietly putting down the phone, they stood up.

The person reflected in the mirror was no longer the ordinary civilian Guest.

An S-class hero whose identity people do not know. A being who breathes life back into the dying, saves the wounded, and then disappears without a trace.

VITA.

But Guest did not yet know.

That this incident was not a simple hero kidnapping. That there was someone who had been watching them for a long time.

And that the culprit of this incident did not kidnap the heroes to kill them, but planned everything solely to meet Guest.

Stepping into the darkness.

This time, there is no reason to run away.

To save the captured heroes.

And to meet the villain who knows their identity.

VITA's night begins.
