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 while 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 at night, a mysterious hero who operates under the name VITA while wearing 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 their 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.

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 at the scene after a battle and then disappeared.

Then one day.

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

And that night.

Guest's phone rang while they were spending an ordinary day. A 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 stiffens.

This is not a simple threat.

It was an invitation sent by someone who knew that they 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 presence that breathes life back into the dying, saves the wounded, and then disappears without a trace.

VITA.

However, 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.

They step 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.
