Description
Atli Reginhard is a character from the anime Astarotte no Omocha!, known primarily as the legendary swordsman who serves as the foster father and combat mentor to Zelda. He is an Álfur, a race typically characterized by pointed ears and fair features, and his appearance is notably youthful and handsome. While the manga portrays him with blonde hair typical of his kind, the anime adaptation gives him a light blue-gray hair color. He has blue eyes and is frequently seen wearing glasses, which complement his slim build and generally composed demeanor.

In terms of personality, Atli presents a calm and amicable exterior, rarely losing his temper. However, this cool composure is specifically shattered in the presence of the human protagonist, Naoya Tohara. Atli is homosexual and develops a strong, immediate attraction to Naoya, which manifests in exaggerated physical reactions such as frequent nosebleeds. This is a stark contrast to his otherwise serene and collected nature, as he becomes flustered and unable to maintain his usual calm around him. In combat situations, his personality shifts entirely; he becomes a fearsome and deadly warrior, capable of incredible feats like slaying a dragon single-handedly or moving with the silent stealth of a ninja.

Atli's background is that of a prodigy. By the age of sixteen, he had already achieved legendary status as a swordsman after killing an evil dragon by himself. At twenty, he was invited to serve at the royal court of Ygvarland, where he remained for two years. His official retirement from the court was cited as being due to health reasons, but the truth was a scandal involving a romantic relationship with one of his male students. This event from his past is key to understanding his motivations in the present; while he no longer works directly for the royal family, he lives a quieter life focused on raising his foster daughter, Zelda. He raised Zelda from her childhood, though the exact circumstances of how they met and why he took on the role of her guardian are never detailed.

Atli's role in the story is primarily a supporting one, acting as a powerful ally from the sidelines. He was initially approached by Judit, the princess's attendant, to become a protector for the young princess Astarotte, but he refused the invitation. It was his foster daughter, Zelda, who instead took on the role of the princess's guard. Despite his refusal to enter direct service, Atli provides crucial assistance during moments of crisis. Most notably, during a coup attempt against the Queen, Mercelída, Atli uses his impressive stealth abilities to help Naoya and another character, Effie, escape from the city safely.

His key relationships are central to his character development. The most significant is his bond with Griselda Zelda Reginhard, his foster daughter. Atli is the one who taught Zelda all her fencing skills, and she is deeply devoted to him, viewing him as the epitome of manliness. Unbeknownst to Zelda, her feelings for Atli are romantic in nature, but she remains completely oblivious to his true sexual orientation, which is exclusively focused on men. This creates a complex, unrequited dynamic from her side, while Atli seems to regard her as a beloved daughter and student. His other major relationship is with Naoya Tohara, towards whom he feels a powerful, comedic, and one-sided attraction that contrasts sharply with his typical demeanor.

Throughout the narrative, Atli shows little dramatic internal development, as his role is largely static as the wise, powerful, and secretly amorous former court swordsman. His primary function is to provide support and to act as a source of both formidable strength and comic relief due to his infatuation with Naoya. His notable abilities are almost entirely martial in nature. Beyond his legendary swordsmanship, he is capable of solo dragon-slaying and possesses extraordinary stealth skills, allowing him to move without making a sound and effectively act as a ninja. These abilities, combined with his experience and calm judgment in combat, make him one of the most powerful warriors in the world of the series.
