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 Ragus. 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 Eye of the Midnight Sun'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 Puli Angel.

As light shines out from the dungeon, Ruben and his team begin glowing themselves and are possessed by elf spirits. Rossa possesses Ruben and the team follows Lira after he crashes through the floor. The five elves attack Mereoleona with a combined Angel Flapping. When she counters their attacks, Rossa attempts to trap and suffocate her in a block of sandstone, but she breaks free and comes for him, which causes Rossa to feel Ruben's terror. Rhya appears and slashes Mereoleona, and the other four rain down more feathers on her. However, she survives and attacks Rhya.

When Mereoleona unleashes her strongest attack, the elves survive with minor injuries at the cost of most of their mana. Seeing that Mereoleona is also still alive, the elves combine their magic for one final attack to finish her off. However, Zora Ideale and Asta quadruple the power of the spell and reflect it back at the elves. The spell passes overhead and detonates behind the elves, and the Knights escape.

Later, Ado brings Rossa and the other elves in the dungeon into the central room. The dungeon is then steered toward the Clover Kingdom and their revived brethren.
