Exploring the reason behind the mystery surrounding Eris’ parting ways with Rudeus in Mushoku Tensei: Jobless Reincarnation

In a nutshell, Eris' decision to leave Rudeus stemmed from her unwavering resolve to set off on a transformative journey to cultivate strength and become more powerful. The ultimate reason behind this self-improvement voyage alongside her loyal servant Ghislaine was her deepest desire to protect Rudeus, the person she cherished above all else.

After witnessing Rudeus’ close call with death at the hands of Orstead, the current Dragon God, Eris was horrified. However, what really bothered her at that moment was her inability to protect Rudeus, leaving an indelible scar on her heart.

Rudeus eventually came back to life after Orstead healed him at the request of Nanahoshi. However, Eris was still grappling with the crushing weight of her powerlessness, which became a haunting reminder that she was incapable of being around Rudeus.

Following a heartfelt night spent with Rudeus, knowing it would be their final encounter, Eris silently left the next morning alongside Ghislaine. Rudeus eventually found chunks of Eris' hair on the floor and a letter on his desk saying:

"You and I aren’t well-balanced right now. I’m going on a journey."

Rudeus was shocked to the core when he learned that Eris had given Alphonse a stern directive not to disclose any information about her journey to him.

Will Eris ever reunite with Rudeus?

As the sole purpose of leaving Rudeus for Eris was self-growth, she would eventually get back together with him. After developing and honing her swordsmanship skills, Eris will be able to defend Rudeus from all here, as she envisioned before embarking on her unprecedented journey.

As seen in the finale of Mushoku Tensei: Jobless Reincarnation season 1, Wake Up and Take a Step, Eris still couldn’t get over Rudeus's influence on her life. After shouting out that she loved Rudeus, Eris proclaimed that she would return once she became a better version of herself, capable enough to face the Dragon God.

However, the road to personal growth and acquiring the strength to stand against the likes of Orstead would not be an easy one for Eris. As it would require a significant amount of time and effort for her to become the version of herself that she envisioned, patience and perseverance would be her only allies.

As for fans who are wondering and anticipating seeing Eris's return in Mushoku Tensei: Jobless Reincarnation season 2, they would be disappointed to learn that her return won’t happen until season 3. This aligns with the progression of events depicted in the original light novel. The second season will focus on Rudeus' growth as he joins the Counter Arrow to embark on a new journey.
