Korneah Sebuld is a goblin and the head of the Seburd Family, one of the three major families that hold influence in the city of Akihabara. He is the owner of an artifact called the King's Seal. As a leader, he is portrayed as strong and decisive, but he also demonstrates a genuine concern for the welfare of the people living in his domain, striving to make the city a better place for everyone. His leadership and reliability are such that the character Hizuki places trust in him and depends on his support. Korneah's background includes being a goblin who once worked for a previous member of the Seburd clan, eventually being granted the family name before that predecessor died. In the story, he serves as a key local figure whose authority and resources position him as a significant power broker within Akihabara, interacting with other main characters from that position. While his specific abilities are not extensively detailed, his ownership of the King's Seal, combined with his role as a family head, suggests he wields both political and magical influence. His development is largely defined by his commitment to his role as a caretaker of the city and his pragmatic approach to maintaining order amid the chaotic fusion of magic and technology in the year 2099.
