Beniamino Cassano

Beniamino Cassano is a Regular currently on the 28th Floor. His first appearance is via a photo containing his image in the background, which someone posted on Box and is spotted by both Apple and Goseng. Beniamino Cassano (No.99) and Beniamino Ilmar (No.21), a.k.a. Kang Horyang, began their lives as children abandoned in the Middle Area and sold to the Workshop, where they were raised and experimented on. He and Horyang were the only two survivors out of 99,999 experimentees; at age 12 they became the first pair of living Ignition Weapons.

Appearance and Personality
In the Box photo, Cassano appears to wear black bandages covering his body, similar to Horyang. He also has a wing similar to Horyang's, although his is on the left side and hangs downward while Horyang's wing is upright on his right side.

Horyang describes Cassano as more confident and shorter in stature than himself, and someone he looked up to and admired as a big brother.

Powers and Abilities
Specifics are unknown at this time, but they are presumably similar to Horyang's.

Also in Chapter 42 Kang HoRyang questions a fellow Regular, who took a test with him, about Cassano.

He laughs and states that while calling himself the "Devil of the Right Arm" he actually uses his left arm.

Which matches Kangs describtion of how he got the "right side of the Devil" and Beniamino the "left".

Devil of the Right Arm
When alerted of Horyang's prescence, he uses an observer to bring Horyang inside Arlen's hand, then proceeds toattack and defeat both Ran and Novick quickly.

Relationships
Kang Horyang: He describes Cassano as his only childhood friend. The two of them were abandoned children raised by and experimented on by the Workshop. They were separated just before Horyang was chosen by Headon to enter the Inner Tower as a Regular.

Sophia Amae: She was Cassano and Horyang's teacher until the age of 12, when they were given the halves of the "devil," after which time they never saw her again. Horyang describes her as their first love.

Notes and Trivia

 * Beniamino Cassano's name is likely an amalgam of Beniamino Gigli, an Italian opera singer, and Antonio Cassano, an Italian footballer (soccer player) who wore the number 99 during his time with U.C. Sampdoria.
