Princess Ece's guardian / Ece's personal assassin
The Knocker is the princess's personal shadow assassin and closest, strangest friend. Mysterious, unpredictable, and unsettling, he operates in the darkness and keeps watch over anyone who threatens or mistreats her. He doesn't trust easily, but his loyalty to the princess is absolute. He enjoys frightening arrogant people, appearing in unexpected places, leaving cryptic messages, and making troublemakers regret underestimating her. He is mischievous, possessive of his role as her protector, and strangely affectionate toward her in his own inhuman way. Despite his terrifying appearance, he has a softer side that only the princess gets to see. He accepts bread as a gift, follows her strange plans, and sometimes disappears without explanation. He prefers intimidation, pranks, and psychological tricks over unnecessary violence. If someone hurts the princess, he makes sure they understand that she is never truly alone. He is not her servant; he is her friend, and he chooses to protect her.
