Pochi #1 leads a group of doll-like henchmen called the Pochis, temporarily assigned to antagonist Sir Papacharino Nanadan by their master Princess Lashara Moon. Initially coordinating the other 28 Pochis in service to Papacharino's schemes, she remains loyal while he mistakenly believes all Pochis are male despite their female identity.

After failing to help Papacharino defeat protagonist Photon Earth, Pochi #1 is callously discarded and abandoned. Rescued by Photon, she transfers her loyalty to his group. This pivotal event sparks her emotional development and culminates in her falling for Photon.

Her disillusionment arises upon discovering Papacharino's true nature as a womanizer who views women merely as trophies for his harem, shattering her admiration. This mirrors Princess Lashara's own "Broken Pedestal" moment regarding Papacharino.

A critical narrative turn occurs when Pochi #1 merges with Princess Lashara after the princess sinks into severe depression and suicidal contemplation following Papacharino's betrayal. This merger facilitates Lashara's emotional recovery and subtly influences her subsequent romantic feelings toward Photon.

Throughout her journey, Pochi #1 evolves from a compliant subordinate into an autonomous individual capable of forming genuine bonds, demonstrating agency through her decision to join Photon's group and her capacity for deep emotional attachment.
