Zenith Greyrat, Paul's wife and Rudeus' mother, was a competent adventurer whose major job in her team was healing magic. Zenith, who was skilled in healing magic (Mushoku Tensei Anime: Episode 1), had a significant supporting role in Fangs of the Black Wolf. Anyone would fall in love with Zenith since she has such a nice and charming attitude. WELL! The celebration was shattered when Paul, the bad boy in her team, fell in love with her (Mushoku Tensei Light Novel: Volume 2) While we cannot say Zenith is a combatant, we will judge her based on her role as an adventurer. Zenith has a remarkable knack for magic, since she is skilled in Water, Fire, Detoxification, and Healing magic. It explains where Rudeus gained his abilities.
Eris makes an appearance in the volume's additional chapter, briefly outlining her training practices centered on conquering the Dragon God Orsted. She practices swinging and honing her sword every day, and on her way back from training, she runs into Auber. Auber blocks Eris' path and asks her if she may send a message to Gul Farion, which she ignores and insists that he go aside. Auber unsheathes his blade as he senses Eris emitting a lot of killing intent, akin to that of a wild beast, and the two duels. Eris is barely keeping up, and the combat was about to turn into a death match when Gal Farion interfered. Auber then appears and begins training Eris. Eris appears in the volume's epilogue, as Reida and her apprentice, Isolte, are summoned by Gal Farion to teach Eris. Eris, Nina, and Isolte begin training together in order to overcome their deficiencies and learn about various sword techniques. She practices to fight Isolte's Water God Style, which is both her weakness and Orsted's primary sword style.
Eris is pretty crazy in bed, but she is quite timid about revealing it to other people. Rudeus had to go through a lot of pain to persuade her to perform a 4 P. Eris, like all others descended from the Boreas Greyrat Household, has a soft spot for Beast Girls. She also likes dogs and cats, which might be an extension of the genetic characteristic.
