Like most fantastical isekai series, Mushoku Tensei features an expansive world with characters that each impact the story in their own way, assisting Rudeus Greyrat on his journey through a new world. While Rudeus and other main supporting characters, like Eris and Sylphiette, bask in the limelight, there are a lot of characters with similar impact whose contributions and backstories enhance the depth of the story and help further it.

When he isn't focused on magic or fighting, Rudeus says some reasonable things.

These characters provide pivotal moments and unique contributions that deserve recognition. From Rudeus’ trusty companions to characters who he has limited interactions with, these are some of the most underappreciated characters in Mushoku Tensei.

6 Cliff Grimoire

Created Magic Tools To Mitigate The Effect Of Curses

Cliff was an extremely proud individual who was introduced into the story as a main character when Rudeus joined the Ranoa Magic Academy. He was born a genius and was able to quickly achieve Advanced Rank in various types of magic, including Summoning and Detoxification.

He fell in love with Elinalise Dragonroad, which motivated him to create magic tools that can suppress the effects of cursed people when he learned about her circumstances. He also assisted Rudeus with some of his great inventions, like the Magic Armor and the Zariff prosthetic hand.

5 Nanahoshi Shizuka

Stopped Orsted From Killing Rudeus, Among Other Things

Nanahoshi is an otherworlder like Rudeus, but instead of being reincarnated into another body like him, she was transported while keeping hers. Her transportation caused the Teleport Incident, and ever since, she has been looking for a way back to her world through studying teleportation circles and magic.

She was taken in by Dragon God Orsted, who protects her from those who might try to harm her. During Rudeus' first encounter with Orsted, she was the one who convinced Orsted not to let Rudeus die after their battle was concluded. She joined the Ranoa Magic Academy and almost instantly became a Class A mage and special student.

4 Zanoba Shirone

Helped Rudeus With His Inventions

Zanoba was originally introduced as a minor character, but as the story unfolded, his importance to Rudeus and the story at large became more and more apparent. He was introduced as one of the spoiled princes of the Shirone Kingdom. However, he is a Blessed Child with the power of super strength.

Following his successful recovery, Rudeus is determined to put things right with Sylphy by his side.

That power has proven to be more of a curse than a blessing, as he was ostracized from his family because he accidentally ripped his brother’s head off when he was just three years old. His strength might be his gift, but he is also highly-intelligent and innovative, helping Rudeus with a lot of his research and inventions as the story progresses.

3 Ghislaine Dedoldia

Trained Rudeus And Eris In The Way Of The Sword

Sword King Ghislaine is the daughter of the Doldia Village Chief, who was a member of Paul’s party when he was still an adventurer. She became a Sword King after being trained by Gal Farion, and was eventually taken in by the Boreas family to serve as their bodyguard following the disbandment of the party, as she could not really survive on her own due to her lack of financial intelligence.

She became Eris and Rudeus' tutor in the way of the sword, and even learned a few things about magic from her students. If not for the interference of Ghislaine, Rudeus’ plan, which was aimed at disciplining Eris, might have ended in one or both of them losing their lives. Her loyalty to the Boreas family knows no bounds, as even after guiding Eris back to Rudeus, she made her way back to Asura Kingdom in order to hunt down and find those who killed her benefactors.

2 Ruijerd Superdia

Protected Rudeus And Eris On Their Journey Through The Demon Continent

One might argue that Rudeus and Eris would not have made it out of the Demon Continent in one piece had it not been for Ruijerd. Following their teleportation, he offered to guard and guide them through their journey due to his extreme soft spot for children. They eventually became friends, with Ruijerd teaching Rudeus and Eris and helping them improve their combat skills.

Superds are a prominent yet often misunderstood race of warriors who endure harsh discrimination throughout the world. Here's why.

He was willing to put his life on the line against the great Dragon God Orsted to save Rudeus, despite knowing he was no match for him. Ruijerd was also tasked with escorting Norn and Aisha to Rudeus’ house in another city, showcasing how deep the bond he has built with the protagonist is.

1 Kishirika Kishirisu

Demon Empress Who Blessed Rudeus

Kishirika Kishirisuis said to be a Demon Empress, but to most people in the anime who have no knowledge about her history, she appears to be a pauper who goes around asking for favors. Those who are kind enough to honor her requests are given Demon Eyes in return. Rudeus has helped her on two occasions and received two great gifts, namely the Clairvoyant Eye and the Foresight Eye, which help make navigating situations easier.

Kishirika also discovered the location of Zenith Greyrat, one of the few people that it was almost impossible to find following the Teleport Incident. Due to the number of lives she has influenced with her gifts, directly or indirectly, compared to the amount of screen time she gets, it is not a stretch to say she is the most underappreciated character in the series.
