Characters

Raphael Delico

Eldest son and heir of House Delico; older brother of Ul.

Personality: Feels intense pressure as the future head of the family and has a strong complex toward his father Dali (whom he sees as an almost absolute figure). Deeply concerned about Ul’s safety and disapproves of Ul’s close relationship with the dhampir Sophie — he repeatedly tries to pull Ul away from him. Used to be close friends with Angelico, but their relationship turns into rivalry. Carries the weight of family expectations and noble duty. Notes: More reserved and duty-focused compared to his younger self; the protectiveness toward Ul remains a core trait.

UI Delico

Youngest son of Dali Delico and younger brother of Raphael Delico

Personality: Curious and intellectually driven. He researches the lost immortality that vampires once possessed and becomes obsessed with the legend of TRUMP (the original immortal vampire). Unusually open-minded for a pure-blood noble, he is strongly drawn to Sophie despite the social taboo against associating with a dhampir. Compassionate and forms a close, almost inseparable friendship with Sophie that drives much of the story. He values life and the natural cycle more than pure immortality in some interpretations of their dynamic. Relationship notes: Younger brother of Raphael. Their family status makes his closeness to Sophie a source of conflict.

Sophie Anderson

A Dhampir of the Clan

Background: Orphan and one of the few survivors of Nebula Village. Transferred from an orphanage to the Clan after showing Cocoon-period symptoms. Personality: Intelligent, skilled in swordsmanship and academics. Faces heavy discrimination and hatred from pure-blood vampires who call him “filthy.” Despite the prejudice, he forms a deep, fateful bond with Ul. Later becomes entangled in the search for the legendary True of Vamp (TRUMP) and the secret of immortality. Appearance notes (from series depictions): Often portrayed with a somewhat delicate/feminine look, consistent with his mixed heritage.

Angelico Fra

Only son and heir of House Fra.

Personality: Born into an elite family with high expectations. Harbors a strong sense of inferiority toward the Delico family and is particularly hostile/rivalrous toward Raphael. His Cocoon-period mental instability is severe; it eventually leads him into extreme hysteria. Leads or is associated with a “Pure-Blood Vampires” group/club. Seeks status and recognition, often through opposition to the Delicos. Notes: The childhood closeness with Raphael has deteriorated into rivalry by this point in the timeline

Dali Delico

Head of House Delico

Personality: Strict with his eldest son Raphael while doting more on Ul. Powerful, prideful aristocrat who remains a commanding presence. Continues to carry the weight of his late wife Frida’s request to raise their sons properly. Appears in supporting capacity in the main story as the authoritative father figure.

Gerhard Fra

Head of House Fra

Personality: Influential aristocratic father. His high status and expectations contribute to Angelico’s pressure and inferiority complex. Maintains the traditional rivalry/friendship dynamic with the Delico family.
