Biography
After the Crimson Lion squad places fifth in the squad rankings, Ruben and the others are berated by their new captain, Mereoleona Vermillion, and she forces the squad to undergo training at the Ultime-Volcano Mountain Trail. Having reached the summit before sundown, Ruben is allowed to bathe in the hot springs.

A week later, Ruben attends the Royal Knights Selection Exam and is placed on Team I with X and Nils. Before their first match, Ruben and Nils question who X is, so Rill drops his disguise.

During their first match, Ruben and Nils destroy the crystal after Rill defeats their opponents. Afterwards they have to drag the captain who is distracted and critiquing his painting. During their second match, Ruben and Nils decide just to support Rill. The pair panic when faced with Team K's Compound Magic, but Rill is able to redirect the Thunder Arrow and destroy Team K's crystal.

During the final match, Ruben and Nils confront Noelle Silva and En Ringard, while Rill fights Yuno. Team I loses when Rill accidentally destroys his own crystal.

Several days after the exam, Ruben and the others selected to be Royal Knights all assemble in the Royal Capital and are placed under the command of Mereoleona. After the squad change into their new robes, Mereoleona introduces additional members and reveals the location of the White Night Eye's base. After the squad travels to the Gravito Rock Zone, Mereoleona explains the situation and divides the squad into teams. Rill infiltrates the dungeon with Ruben, Fragil Tormenta, and Paulie Angel.
