Arizain Ohm is a college student in an unknown university who joined the subversive organization known as the Laniakea. He was provided a titanium glaive as a weapon.
His Above and Beyond counterpart is Ariana Ohm.
At some point in 2018, Arizain Ohm enrolled in Philippine Science High School's Main Campus.
Arizain catches the attention of Sachikayla and Tyriann, and they assign Nyliae to track him down. They quickly encourage him to go on a mission to pick open the teachers' lockers, where he distracts the teachers while the others do the job. He was rewarded with money for his time, and was told something better was to come.
Later on, Tyriann provided him with a crimson glaive made of solid titanium, as he provided Fuschia something similar. He used it to help the Astatines win their Math Intersection, and much later on, he helps recruit Guinevere into the organization that would later be known as the Laniakea.
Arizain attends the batch's Graduation Ball after he graduates high school. During the ball, he loses his memory due to the cataclysmic result of Sachikayla and Tyriann's falling out.
To be added
Arizain is hungry for action and usually jumps on the opportunity whenever it arises. He doesn't mind causing mischief, or better yet, keeping it hidden from others in authority. He is extremely loyal to the Laniakea primarily due to the L.E.N.S.es affecting his mind, though the incident at the Graduation Ball has changed that momentarily.
