Code Black: File AV

After the death of their elite secret-agent parents, four siblings-Shido, Marinette, Sahara, and Tsunami Kimihito-are forced to leave everything behind and move to Japan. Enrolled at Kimetsu High, they do their best to fit in and hide their true nature-each of them rare fox-type yokai with nine mystic tails and terrifying elemental powers.
But fitting in isn't easy when you're hiding more than just your ears.
As they navigate their new life, strange clues begin to surface-messages, files, and secrets their parents left behind. The siblings soon discover their family was entangled in a global conspiracy, and that their parents didn't die by accident... they were eliminated.
Now labeled as File AV, the siblings are recruited into an underground spy organization called Code Black, training under the guidance of their aunt-Principal Sakura Sakamoto, a top-tier agent hiding in plain sight.
But as they dig deeper into their parents' past, a new threat emerges-Abigail Harmon, a cunning wolf-girl who starts off as a new friend but might just be the deadliest double agent they've ever encountered.
With their lives, their powers, and the truth on the line, the Kimihito siblings must fight through betrayal, uncover buried truths, and step into the roles they were born for.
Because in this world, trust is a weapon...
And the code has been activated.
This is File AV.
This is Code Black.
