Though absent for the majority of the main story, he played crucial roles in Arc 1 and Arc 5 , a supporting role in Arc 9 , and a lesser supporting role in Arc 3. Born to House Astrea , Reinhard mastered the sword at a young age following the untimely death of his grandmother and succeeded her as the next Sword Saint a few years later.
However, due to his immense power and various problems in his own family, Reinhard lives a rough life estranged from his family. Despite this, he is a knight willing to use his power to protect the Kingdom of Lugunica. After fending off the Bowel Hunter at the Stolen Goods Warehouse, he discovered the last of the Royal Selection Candidates, Felt, and he subsequently pledged his loyalty to her as her knight.
Reinhard stands at exactly six feet tall, making him several inches taller than Natsuki Subaru. His most striking feature is his distinct flaming red hair that shines as brightly as Felt's crimson eyes. His sparkling blue eyes portray a sense of confidence and recklessness. His slender frame features an array of well-toned muscles, although they're usually hidden by his clothing. The Sword Saint exuded an aura of gallantry, and, at a first glance, he gave off an intimidating air that indicated him as someone who is above the norm.
His extraordinarily handsome face, beyond average looks and his open, calming and approachable personality makes him very popular with people, which catches the eye of many women, further exemplifying his magnificence. As a member of House Astrea, Reinhard's flaming red hair and sky blue eyes were traits passed down from the first Sword Saint Reid Astrea , and, in Reinhard's case, inherited from his father Heinkel Astrea.
However, the visual similarities between Reinhard and his father more-or-less ended there. Instead, many of Reinhard's features were taken from his inhumanly beautiful mother Louanna Astrea.
