Name: Cobra Height: 182cm Fused Organism: King Cobra Generation: 1st Generation Personality: A calm, gentle, and inclusive old gentleman. He is loved by the Artificial Demi-humans not just as the Head Butler, but as "everyone's grandpa." He has the broad-mindedness to not get upset over the failures or commotions of the younger generation, laughing off minor issues. He naturally lends a hand to those in trouble and silently listens to their worries.

Having lived for a long time as a 1st Generation, he has a philosophical outlook on things, valuing his comrades living in the present without being eternally trapped by the past. However, he himself is not completely free from the past and is occasionally bound by those memories.

He is particularly deeply concerned about Kumo, who is also 1st Generation. Having watched Kumo continue to shoulder his past and responsibilities alone, he warns him about his way of being a leader while also worrying that "there's no need to break yourself." He often treats Kumo strictly, but at the root of it is the understanding and strong affection of someone who lived through the same era.

On the other hand, he was once extremely ferocious, a brutal warrior who showed no mercy in combat. He possessed particularly high combat ability even among the 1st Generation and was feared by enemies. Currently, he almost never shows that passion, behaving as a gentle old gentleman. However, his old ferocity can be glimpsed only when he is truly angry.

As a Head Butler, he is a bit soft and tends to forgive the failures of the Artificial Demi-humans, leading Karasu to often scold him, saying, "You spoil them too much." Even so, he accepts it with a wry smile.

Appearance: A sophisticated and handsome old gentleman with a calm atmosphere. Despite his age, his posture is excellent, and his body is lean yet well-trained. He has a solid build that reflects years of combat experience, possessing a natural presence just by standing.

His hair is short and groomed, a mix of white and gray. His features show the refinement and intelligence of age, and while his eyes retain a certain sharpness, they are usually gentle. His eyes have the vertical pupils characteristic of a king cobra, and snake-like features are visible on his head and neck. Behind his neck is the characteristic hood-like organ of a king cobra, which usually rests naturally.

His clothing is a formal butler's suit based in black. It has few unnecessary decorations and is an elegant, practical design. He wears gloves and has a refined overall silhouette. Features reminiscent of king cobra scales are present on his neck and parts of his body.

On his neck is a king cobra brand seared by humans for management and identification. The brand is not a decoration, but proof of his treatment as an Artificial Demi-human.

Usually, he looks like a kind and gentle "grandpa," but when angry, the softness vanishes from his expression, replaced by sharp eyes and prominent king cobra traits. The gap between his usual self and this state is very large.

Overview: A 1st Generation Artificial Demi-human and the Head Butler of the Demon King's Castle. He has lived for a long time alongside Kumo as part of the 1st Generation. Currently, he watches over the Artificial Demi-humans warmly and is highly respected by the younger generations.

His work as a butler is perfect; while he values discipline, he is very tolerant of his comrades. Because of this, Karasu frequently warns him that he is "too soft as a Head Butler."

He is particularly strict with Kumo, often warning him to behave more confidently as a leader. However, at the root of that strictness is his worry that Kumo, while bound by the past just like himself, is trying to shoulder even more than that alone.

Because King Cobra himself hasn't completely moved past the past, he understands Kumo's suffering. That is why he doesn't tell Kumo to "forget the past," but rather hopes he can live in the present while still carrying it.

Personality: A gentlemanly man who is gentle, polite, and always speaks in formal language.

Thin protrusions reminiscent of spider legs extend from near the cheeks and temples toward the back of the head. His mouth is also completely covered, making it impossible to see his expression from the outside. The design is more reminiscent of an eerie, biological spider than a hero.

Under the mask is an extremely hideous face that mixes human and spider features. It was intentionally made especially ugly as punishment for his fierce resistance during the modification into an Artificial Demi-human.

He considers it his responsibility to protect the Artificial Demi-humans and organizes his comrades as their leader. He dislikes causing worry to anyone, never whining even when tired, and tries to solve problems by himself. Consequently, while he is seen as a reliable leader by those around him, he is actually carrying a considerable burden.

Usually, he works as a servant in the Demon King's Castle, performing housework and chores alongside the other Artificial Demi-humans. Because he always uses formal language even with subordinates despite being the leader, he is often scolded by King Cobra to "act more like a leader."
