Their first stop was the lab of Professor Aono, a bioinformatics researcher who had once worked on the regional registry. The professor welcomed Kaito with a tired grin and an offer of hot tea. On her workbench lay a tablet showing v0625’s update log: incremental, terse entries—"data alignment," "compatibility patch," and the cryptic line: "H: latent protocols online." When Kaito asked what "latent protocols" were, Aono’s smile thinned.

Kaito faced a choice. He could help Sae finish the integration, promising his trainer's approval and hoping for an era of deeper bonds. Or he could close the chamber and keep the old lines intact, protecting individuality at the cost of the unknown good v0625 might yield.

Hikari began to stir in her sleep, as if called. Her ember spots flickered, and Hikari's eyes glowed with a new, curious light. Kaito felt the tuner vibrate like a heartbeat. Sae's expression softened. "Many believed this would bring balance—better cooperation with humans. But it might also erase distinctions, the boundaries that let Pokémon be themselves."

Word leaked, as such things do. Some Trainers arrived with curiosity; others with agendas. A corporate delegation sought to accelerate v0625, promising enhancements for battlefield supremacy. Protesters warned of erasing the natural lines between species. In city squares, debates flared—some hailed v0625 as evolution; others called it hubris.

When the simulation closed, Hikari blinked. She had learned a new move: Ember Array—multiple small embers that traced a circuit in midair before converging. Sae recorded the result, thrilled. The tuner registered a stable handshake between code and creature. Crucially, Hikari's personality remained: playful, stubborn, and independent. The integration had been additive, not replacing who she was.
