The Greyrat family is overjoyed when Zenith announces that she’s pregnant with a second child, but the mood takes a dour turn when Lilia reveals that she is also pregnant and Paul is the father. Will this be the end of Rudy’s happy family?

Rudy arrives in the city of Roa, where he’s supposed to spend the next five years tutoring the daughter of the local lord. His student, however, is more than he bargained for, and he’ll have to fight to start his first ever job, let alone keep it.

Rudy reaches his 10th birthday, and Eris and her family plan a surprise party for him. Meanwhile, the strange orb hovering over the city remains a mystery as powerful entities across the world begin to take note of it.

Rudeus, Eris, and Ruijerd arrive in the Holy Country of Millis, where Rudeus's thoughts turn to home. When the three split up for a day off, a chance encounter in an alley leads Rudeus to a shocking reunion.

In the aftermath of their disastrous reunion, Paul and Rudeus reflect on their actions and look for a way forward.

Rudeus sinks into depression following Eris's departure. As he struggles to get back on his feet, the many people he's met continue their own journeys.

Rudeus receives a letter from Paul. The letter explains that Norn and Aisha, Rudeus's younger sisters, have been sent to join Rudeus. Meanwhile Nanahoshi continues her research into summoning magic for a way to return to her original world.

Rudeus's sisters arrive with an unexpected chaperone. After catching up with an old friend, Rudeus decides it's time to send the girls to school. But convincing Norn and Aisha turns out to be more trouble than he bargained for.

Norn shuts herself in her dorm room and refuses to attend classes. Haunted by the specter of his past life, Rudeus sets out to solve his sister's problems, only to discover that he is the cause.
