OVA
Description
Compa is a nurse-in-training from the nation of Planeptune and serves as one of the central supporting characters in the Hyperdimension Neptunia series. She is recognized for her gentle and caring demeanor, combined with a dedication to helping others that defines her role throughout the story. Her name originates from Compile Heart, the video game developer responsible for producing the Hyperdimension Neptunia franchise.

In terms of background, Compa is a resident of Planeptune who dreams of becoming a full-fledged nurse. Her journey intersects with the main plot when she discovers the injured protagonist Neptune, who has crash-landed near her home. Taking the amnesiac goddess into her care, Compa becomes one of Neptune's first and most loyal friends, setting aside her training to accompany her on the quest to save the world from the antagonist Arfoire. In the specific OVA "Hidamari no Little Purple," also known as "Little Purple Sunshine," Compa appears alongside IF and Histoire at the Planeptower. They arrive to witness the young CPUs who have been transformed into children and later join the search party to locate the missing younger Neptune.

Compa's personality is defined by her profound kindness and selflessness. She takes her aspiration to become a nurse very seriously and adheres to a personal code of never leaving an injured person to suffer, regardless of their allegiance. This principle is dramatically illustrated when she provides medical treatment to Warechu, a member of the antagonistic Arfoire Syndicate of International Crime, before even confirming his identity. Despite her nurturing nature, Compa often exhibits a ditzy and clumsy streak, which leads to comedic situations, such as accidentally bandaging Neptune too tightly. However, her fluffy demeanor is contrasted by unexpected traits, including a surprising proficiency for mathematics and a hidden assertive side that can emerge when she is pushed too far.

Compa's primary motivation is the health and safety of others. Her actions are guided by her medical ethics and a desire to protect her friends. This is evident when she joins Neptune and IF on their perilous journey to gather Key Fragments and rescue Histoire, motivated by the belief that it would be impolite to save an injured person while ignoring the plight of the townspeople threatened by monsters. Her role in the story is predominantly one of support. On the battlefield, she acts as the group's main healer, wielding a giant syringe as her primary weapon. Her abilities are largely restorative, focusing on healing hit points, removing status ailments such as poison and paralysis, and guarding allies from harm. In dungeon exploration, she possesses a unique ability known as Monster Call, which allows her to summon monsters to the party, a skill that can be strategically used to encounter specific enemies or bosses.

Compa maintains several key relationships that are central to her character. Her most enduring friendships are with Neptune and IF. She shares a particularly close bond with Neptune, whom she affectionately nicknames Nep-Nep. Her trust in her friend is unwavering; she remains unshaken by Neptunes frequent disappearances or antics, fully believing she will always return. Her relationship with IF is that of a long-time friend, with Compa nicknaming her Iffy. The two are often seen working together as a duo, co-hosting events and interrogating villains, complementing each other's strengths and compensating for their weaknesses. She also shares a sisterly bond with Neptunes younger sister, Nepgear, whom she calls Gear-chan.

Throughout the narrative, Compa shows subtle but noticeable development. While she begins as a clumsy trainee, her experiences alongside her friends allow her to grow in confidence and skill. In later story arcs, such as in Megadimension Neptunia VII, she takes on more active roles, helping to stabilize Planeptune after a dimensional rewrite and investigating mysteries alongside the main party. Her dedication to her craft eventually leads her to resume training at a free clinic, where she becomes popular among her patients. In combat-oriented spin-offs, her role adapts to the setting, appearing as a medical ninja, a shopkeeper, or a beta tester healer, showcasing her versatility and the universal nature of her supportive skills.
