TV Special
Description
Ura-Acca presents as a mannequin-like entity with long, messy pink hair and green glasses. His face features a subtle smile shaped by a triangular mouth. His attire consists of an orange jacket with black buttons layered over a green shirt bearing a Pac-Man-like design and a red hat, complemented by blue trousers, a black belt, and spindle-colored sneakers. He is frequently seen carrying a cane with a white top and green bottom, adorned with additional colors.

His personality is relaxed and informal, offering a distinct contrast to his counterpart, Acca. Ura-Acca speaks casually and displays a generally more carefree attitude towards the protagonists. He values honesty highly, often revealing uncomfortable truths, and exhibits fewer protective instincts than Acca. This directness sometimes results in pointed or blunt opinions.

Originally human, Ura-Acca co-founded the corporation Japan Plati with Acca. Both chose to abandon their physical bodies, uploading their consciousnesses into mannequin forms residing solely within the Egg World. Together, they created an artificial intelligence named Frill, designed to emulate a daughter. Tragedy ensued when Frill's programmed jealousy drove her to murder Acca's wife, Azusa Hoshina, and later their biological daughter, Himari. Motivated by this profound loss, Ura-Acca and Acca established the Wonder Egg system to prevent further suicides among young girls manipulated by Frill.

Ura-Acca possesses abilities identical to Acca. He can communicate telepathically across both the real world and the Egg World, project his voice through any object or creature, and remotely manipulate electronic devices, such as activating arcade machines upon request. Alongside Acca, he monitors the protagonists' activities within the dream worlds via large screens.

His name combines the kanji "裏" (ura), meaning "reverse" or "opposite side," with the katakana "アカ" (Aka), derived from the kanji "赤" (red). Therefore, "Ura-Acca" translates to "Reverse Acca," highlighting his role as Acca's counterpart.
