Reinhard van Astrea/Relationships

Heinkel Astrea
In the past, Reinhard's father, Heinkel, was the only one who stood by him when everyone blamed him for his grandmother's death due to him inheriting the Divine Protection of the Sword Saint at an inopportune time. However, after his mother fell into a coma, Heinkel gradually became an alcoholic and started neglecting his son.

In the present, Reinhard has a very toxic relationship with his now alcoholic father. He basically allows his father to take advantage of him by using his standing as the Sword Saint to maintain his own position in the Royal Guard. Ultimately, what remained of their familiar bond was shattered when Reinhard killed his reanimated grandmother, causing Heinkel to vow to ruin his son's reputation.

Louanna Astrea
As Reinhard was only two years old when his mother, Louanna, fell into a coma, it is unknown if he even remembers her from before that.

Theresia van Astrea
Theresia was possibly the dearest relative he ever had. Reinhard worried a lot about her and became discouraged when he heard that she died. Sometime later when the Witch Cult resurrected her, Reinhard killed her with ease because for him his grandmother was dead and that thing was a corpse, following into more conflicts with his grandfather Wilhelm.

Wilhelm van Astrea
Wilhelm's relationship with his grandson is very tense, likely because Reinhard inherited his wife's power as the sword saint just before she died, making her much weaker than she was at her prime. Nevertheless, Wilhelm did want to fix their relationship after the Hakugei was successfully killed. However, after Reinhard was forced to kill Theresia's resurrected corpse, Wilhelm asked his grandson if he had any regret doing so. After hearing Reinhard's answer, he begins calling the current Sword Saint by his full name, showing that he sees him now as a stranger rather than his grandson.

Natsuki Subaru
Due to Reinhard's friendly and accessible personality, he easily befriended Subaru without thinking of him as inferior to him, despite himself being better than Subaru in every aspect imaginable. After Subaru's impressive feats of defeating the White Whale and the Sin Archbishop of Sloth, Reinhard started thinking of Subaru as his equal and was perfectly fine with relying on him, despite Subaru majorly lacking in strength, speed and battle experience. Together, they were able to defeat Regulus Corneas, whose Authority of Greed made him immune to outside interference, giving even Reinhard some trouble.

Felt
As a part of Felt's faction, Reinhard is willing to do everything in his power to make Felt the 42nd ruler of Lugnica.

Julius Juukulius
Julius and Reinhard know each other since their childhood years. They are both highly respected members of the Royal Guard. They both consider each other as best friends.
