Sieghart Saladin Greyrat/Relationships

Rudeus Greyrat
Rudeus Greyrat is the main protagonist of Mushoku Tensei and is Sieghart's father. As a child, Sieghart listened to his father's stories about 'Cheddarman' and being an ally of justice, values he will still bring way later into his older years. Like many of the kids in the Greyrat family, Sieghart deeply respects him but also believes that his father has no expectations of him. This is because Rudeus raises his children freely which the kids misinterpret as him having no expectation for his children when in truth it's actually the opposite. He tries his best to please his father by doing what he thinks his father wants and when he fails, he felt that he disappointed him. Sieghart only knew the truth about his father's intention after he and his father had a heart to heart the night before Sieghart leaves Sharia to find Pax.
