Arc-En-Ciel

A Next Doll, one of the strongest Chimeric Monsters created by Promestein. Boasting overwhelming physical ability, she was created to counter Granberia. Her body was improved upon with muscle tissue strengthening, ultra-fast synapses, metabolic over limit through magic, and skin reinforced with nano-carbons.

As a result, her strength, agility, and defense are all unmatched by any force in the Heavens or surface world. The only apparent weakness is her incredible need for energy to maintain her body.

Due to the intense strain on her own body, her lifespan is extremely short. Her life is believed to be maxed out at five years, at the most.
