Description
Ena Ibarada is a second-year graduate student at Saitama University, collaborating with researchers Ayame Himuro and Shinya Yukimura. She possesses a petite stature, long wavy lavender hair extending to thigh-length, and bright slanted purple eyes. Her typical outfit is a lab coat worn over a goth or pajama-like dress featuring a neck ribbon tie, often paired with gloves. She regularly wears dark pantyhose and goes without shoes.

Ena displays a whimsical, intelligent personality, sometimes exhibiting cat-like behaviors. Her primary motivation is playing video games, showing little interest in professional goals or other pursuits. She finds entertainment in provoking chaos, frequently achieved by teasing her childhood friend Kosuke Inukai or mocking Shinya Yukimura. Despite a seemingly detached attitude, she actively engages in lab activities, especially when opportunities for amusement present themselves.

Her background includes a long-standing relationship with Kosuke Inukai, defined by shared gaming interests and a history of mutual teasing. A notable childhood incident involves her witnessing Kosuke's first ejaculation during an erotic game session. She nicknames him "Torasuke," based on a kanji pun.

Within the lab dynamic, Ena acts as an observer and occasional instigator. In one instance, after oversleeping on a lab couch due to all-night gaming, she intervened in Shinya and Ayame's experiment measuring heart rate responses to physical touch. She proposed expanding their methodology to include a control group, suggesting Shinya touch multiple women's heads to determine if his elevated heart rate was specific to Ayame or generalized. She anticipated and later confirmed Shinya exhibited nervousness around all women, explaining that heart rate fluctuations stem from various situational factors beyond romantic attraction. Following this, she returned to sleep on the lab couch, displaying indifference to Ayame's frustration.

Character development reveals a self-identified "chunibyo" phase during her graduate studies, marked by adopting a dramatic, pessimistic worldview and wearing frilly goth clothing beneath her lab coat. This persona included narrating her life in bleak, theatrical tones. This affectation diminished as she acknowledged the positive aspects of her life, particularly the camaraderie within the lab and her evolving relationship with Kosuke. Her perspective shifted upon recognizing her friends' support and her academic environment's fulfillment, leading her to discard the chunibyo persona and focus on pursuing her doctorate.

Her name "Ena" (恵那) combines "favor, benefit" (恵) and "that" (那). Her surname "Ibarada" (棘田) translates to "thorn, spine, splinter, biting words, bush, thicket" (棘) and "field, rice paddy" (田).
