Ryota Sekiguchi (関口 良太 Sekiguchi Ryouta?) is a student at Freedom Academy and an Otherworlder.


Although Ryota is a timid guy, he is very scary when angered.


Ryota appears like the average middle-schooler kid, with black eyes and neck-long black hair. He wears the classic uniform of the Freedom Academy.


After being summoned by some country, he was rescued by Yuuki Kagurazaka and placed in the care of Shizue Izawa in Freedom Academy's Class S. There he learned that he had only a few years at best left to live. After Shizu left him and the other members of Class S, they drove off any replacement teachers before they were eventually put under the tutelage of Rimuru Tempest. Rimuru challenged all of them to a spar, and come Ryota's turn, he showed off his berserker skill before being quickly taken care of. Eventually, Rimuru took him and the other members of Class S to Ulgrasia Republic so that they could form pacts with greater spirits to calm their rampaging energy. Once at the Dwelling of Spirits inside the Labyrinth of the demon lord Ramiris, Ryota prayed at the alter and lesser spirits of both water and wind responded. Rimuru then used his Unique Skills to synthesize them into a greater spirit containing both elements, which then stabilized the magicules rampaging inside Ryota's soul.
