Description
Berecca worked as a scientist at the World Ninja Association's Research Institute, collaborating with Burton and Ron on the classified Ninja-Gum project for three years. Her scientific path honored her father Sean, who reportedly died in a WNA experiment accident in Oedo; the institute withheld specifics, fueling her unresolved grief. After repeated failures, Burton accidentally perfected Ninja-Gum using Goro’s bell. Berecca ingested the prototype, activating her latent shinobi DNA to gain ninjutsu abilities but instantly de-aged from adulthood to childhood. This transformation occurred moments after she witnessed Ron betray the team to steal their research.

She now appears as a fair-skinned child with magenta-pink hair in a large pompadour ponytail held by blue pins and light blue eyes. Her outfit consists of a bright yellow hoodie jacket with purple accents and a skull patch, dark jean shorts, pink-and-purple striped thigh-high socks featuring cartoon skulls, and blue sneakers with red laces and soles. As an adult researcher, she wore a grey tank top, jean shorts, striped leggings, turquoise shoes, and a white lab coat.

Her personality blends quick-tempered competitiveness and impatience with underlying gentleness and determination. She often uses sarcasm, especially toward Burton, whom she protectively cares for. Trapped in a child’s body, her adult perspective surfaces through occasional swearing. Mission impulsiveness leads her to favor action over strategy.

Seeking to reverse her de-aging and uncover her father’s death truth, she enrolled in the WNA Academy under Genryusai. During an Oedo mission, she discovered Leonard—her father’s presumed-dead lab partner—as a WNA intelligence operative. Pursuing him triggered clashes with shadow ninja and space ninja forces. Leonard warned her to stand down, but she persisted, theorizing he might shield her. Her investigation revealed her father studied dark energy-infused stones gathered by the WNA, with Leonard holding critical incident knowledge.

In combat, she wields Ninja-Gum to manifest weapons like the Sushi Axe and Paw-xing Gloves, demonstrating resilience against enhanced foes like energy-corrupted space ninja. Genryusai mentors her in tactical restraint, while she confronts emotional triggers tied to her father’s legacy.

Additional traits include her January 21 birthday, fear of horror media, and poor cooking skills resulting in burnt food. She models for the "1080" brand in promotional material and in-game shops. A spiritual quest involved overcoming a rival’s illusion guided by Akiko, a crystal-based guardian spirit.
