Ena Ibarada, a second-year microbiology graduate student in Saitama University’s Ikeda Laboratory, combines academic rigor with striking features: lavender hair cascading past her hips, purple eyes, and a signature white lab coat paired with a tie. At 142 centimeters tall with blood type AB, her poised presence exudes intellectual focus. Methodical and analytical, she dissects challenges into structured components, driven by a disciplined work ethic and quiet dedication to research. Though introverted and self-reliant, she collaborates thoughtfully, balancing team dynamics with pragmatic insights while respecting peers’ perspectives. Her dry humor surfaces around childhood friend Kosuke Inukai, with whom she shares a bond forged through handheld gaming sessions and lighthearted rivalry. She playfully needles him about a dating sim character mirroring her likeness—a detail he sidesteps—and reveals a subtly competitive streak, particularly in scenarios involving him. Rooted in a passion for scientific inquiry, Ena prioritizes logic yet intermittently softens, offering discreet encouragement to struggling colleagues. Moments of unguarded emotion, such as rivalry tinged with romantic tension, pierce her otherwise detached facade. Personality frameworks classify her as ISTJ/ISTP, reflecting her preference for order and hands-on analysis, while Enneagram Type 5 underscores her thirst for mastery and occasional withdrawal into solitary pursuits like experimental tinkering or immersive reading. Within her narrative role, she anchors teams with technical expertise and understated emotional support, her reliability and evolving willingness to connect subtly shaping both lab endeavors and interpersonal growth.
