Yurika Sasaki trains as a voice actress among five main characters at Lambda Eight school. She possesses pink twintails, green eyes, and a teenage appearance, typically wearing detached sleeves, mini skirts, and boots. Her profound love for anime fuels her ambition to enter the profession and achieve fame, specifically aspiring to grace magazine covers. Yurika exhibits high energy, confidence, and occasional hyperactivity.

A childhood pinky promise with anime artist Atari Maeda—that he would animate her debut—drives her urgency to succeed. Upon learning of Atari’s industry debut, she rashly pursues her own, falling victim to a fraudulent company. This incident causes her temporary withdrawal from Lambda Eight before Momoko and Atari intervene.

Yurika’s feelings for Atari spark jealousy toward Momoko Ichihara, who shares a group home with him, creating a love triangle. This tension peaks when Yurika schedules a date with Atari conflicting with Momoko’s professional opportunity involving her idol, Minato Ichinose. The romantic conflict dominates her character arc mid-series.

After resolving the love triangle, Yurika reconciles with Momoko. She continues her voice acting pursuits alongside peers, engaging in collaborative projects like stage performances where they support each other professionally. Her journey navigates the challenges of balancing ambition, relationships, and career growth within the industry.
