Jonah

Jonah is a scientist who was hired by the Sphere to design an Anti-Seijin holding cell on the Monolith for a very special Seijin.

He predicted that he would be executed after the job was done, compelling him to escape. He was intercepted by the pirates who asked for his help to sneak Mahad and Lena onto the Monolith. He reluctantly accepted (convinced the Sphere wanted him dead either way) and lent Mahad his ID card so that Mahad would scan as him.

While they were infiltrating the monolith, he took off in the Hyperion but was captured by Diwan. After a series of fights on the Monolith, Jonah escaped with Mahad and Lena so the Sphere could never use his genius.

Jonah was seen in the episode "Infiltration."
