Description
Heli is one of the main characters of the anime Dark Moon: The Blood Altar. He is a vampire in the twelfth grade at Decelis Academy, making him the oldest among his seven vampire companions. He also holds the position of captain and center of the school's Nightball Team. Heli is instantly recognizable for his calm and composed demeanor, serving as a steady anchor for his more unique brothers.

In personality, Heli is defined by his immense patience and warm-hearted nature. He is dependable and observant, often analyzing situations quietly before acting. His most distinctive trait is his telepathy, which allows him to communicate directly with his brothers without speaking. This ability underscores his role as a silent leader who is always connected to those he cares about.

Heli becomes deeply entangled with the protagonist, Sooha, from the moment she arrives at Decelis Academy. Upon seeing her, he experiences a vague but powerful sense of longing whose origin he does not fully understand. When he discovers that Sooha possesses superhuman abilities and is hiding her identity to avoid being mistaken for a vampire, he does not react with fear or hostility. Instead, he calmly offers her friendship and reassures her that he knows she is not a vampire, becoming a source of safety for her in a hostile environment.

His motivations are intrinsically linked to Sooha and his brothers. As a group, the seven vampires are curiously and instinctively drawn to Sooha, feeling as if they would do anything she wishes. Heli takes it upon himself to shield her from the centuries-old conflict between vampires and werewolves, even as her presence begins to unravel unsettling secrets from their own past. Over the course of the story, Heli develops from a curious observer into a fiercely protective figure. His connection to Sooha deepens into a romantic arc, where he is portrayed as her "red thread" or fated partner, and he displays moments of jealousy regarding her safety and attention from others.

Beyond his telepathy, Heli possesses standard vampire physiology and the power of telekinesis, allowing him to move objects with his mind. His calm and dependable leadership style is his greatest asset, as he works alongside his brothers, including Jaan, Jino, Shion, Jakah, Noa, and Solon, to navigate the dangers of their world.
