Daidalos serves as a pivotal entity within Synapse, the enigmatic realm responsible for Angeloid creation. Emerging initially as a cryptic presence, her influence deepens through direct interventions in the lives of central figures.

She engineered Sohara Mitsuki as a synthetic replica to supplant her deceased original avatar—a girl who succumbed to illness in childhood. Driven by the need to preserve Tomoki Sakurai’s memories of the lost companion, Daidalos imbued the clone with the avatar’s recollections and traits. Unaware of her artificial genesis, Sohara evolved alongside Tomoki as his childhood confidant, mirroring the original’s bond.

As Synapse’s architect and overseer, Daidalos commands profound insight into Angeloid systems, including combat-focused models like Ikaros. She disseminates critical knowledge about their origins and functions, yet remains guarded when probed on specifics—such as confirming Synapse’s memory-altering protocols during inquiries into Hiyori Kazane’s anomalies.

Her exchanges with Eishiro Sugata accentuate her elusive demeanor. While recognizing his doubts about Hiyori’s identity and the constructed nature of their world, she evades full disclosure of Synapse’s reach. This calculated ambiguity cements her dual role as both emissary and arbiter, navigating the divide between Synapse’s clandestine agendas and earthly actors.

Though her physical form and combat prowess align with Synapse’s technological motifs, they remain undefined. Her decisions prioritize systemic equilibrium, yet subtle empathy surfaces in her dealings with Angeloids and humans entangled in Synapse’s designs.
