After the death of a woman he once failed to protect, rogue shinobi Natsuki is left with one final mission—deliver her daughter, Rumi, to safety in Shin-Kage Village.
But the world has other plans.
Attacked by a powerful oni, Natsuki dies trying to protect the girl. Just when everything seems lost, he awakens—reborn by the mysterious Ink Master System, a power that lets him turn anything he draws into reality.
Now hunted by monsters, stalked by a past soaked in blood, and armed with the ability to summon living beasts, deadly weapons, and tactical clones from pure ink—Natsuki will stop at nothing to protect the child he swore to save.
Even if it means becoming a living weapon to do it.
