Description
Berecca serves as a lead Ninja-Gum researcher at the World Ninja Association's Research Institute, collaborating with Burton and Ron for three years to develop the substance. Her work honors her late father Sean, who perished in a classified WNA experiment accident in Oedo. During final testing, a cat's bell contaminated the formula, triggering an explosion that produced a prototype. After consuming the gum, Berecca awakened latent ninja powers but regressed into a child. Witnessing Ron attack Burton exposed Ninja-Gum's weaponized purpose, shattering her expectations and driving her to join the Ninjala Tournament with Burton to reverse the effects.

Transformed into a fair-skinned child, Berecca has magenta pink hair swept into a pompadour ponytail secured with blue pins, and light blue eyes. She wears a bright yellow hoodie-like jacket with purple accents and a left-arm skull patch, dark jean shorts, pink-and-purple striped thigh-high socks featuring cartoon skulls, and blue-and-white sneakers with red laces and soles. Pre-de-aging, her lab attire included a grey tank top, blue jean shorts, striped leggings, and a lab coat.

Competitive and strong-willed, Berecca displays impatience and sarcasm toward colleagues like Burton, though she cares deeply. Her relentless pursuit of answers about her father's death and Ninja-Gum is tempered by a short temper that sparks recklessness—like ignoring retreat orders—a flaw she acknowledges. Beneath her tough exterior lies vulnerability about her past and a fear of horror media. Promotional art confirms her notoriously poor cooking skills.

In Story Mode Chapter 2, Berecca trains under Genryusai and volunteers for an Oedo mission under the pretext of visiting her father's grave. There, Leonard—her father's presumed-dead lab partner—warns her against investigating. Ambushed by shadow and space ninja, she observes the latter's power-enhancing absorption ability. Persisting, she battles a Lion Dance Car and Robo-Yokozuna Gorikimaru alongside Kappei and Gen'unsai. Retrieving a corrupting-energy dark stone from the machine, she theorizes the WNA collects such stones and that her father studied them, suspecting Leonard holds answers. The mission fuels her resolve to expose WNA secrets while implying Leonard's protective motives.

Trivia notes her January 21st birthday, her role as the 1080 brand's female model in shops, frequent promotional appearances, and her status among the few characters using mild profanity.
