OVA
Description
Eriko Takeda holds dual roles as the homeroom teacher for Class 3-C and the school nurse at Sakaimachi Academy. Posing initially as a transfer from Europe, she displays unconventional habits like smoking during work hours and wearing revealing clothing under her lab coat, traits she blames on unfamiliarity with Japanese norms. Her distinct appearance features thigh-length magenta hair, typically tied in a low ponytail, with bangs covering the left side of her face, blue-green eyes, and a curvaceous figure noted as 96-60-87 cm.
Her true identity is Aichlikkwadrou, a scientist who collaborated with her lover Abel researching the Tree of Vrinda and parallel worlds. They developed a device enabling consciousness travel across dimensions. During testing, an ethereal entity corrupted Abel's mind, attacked Aichlikkwadrou, and escaped, later becoming known as Ryuzoji. Seeking revenge, she joined the Dimensional Inspector Bureau, an organization tracking criminals across space and time. Adopting the alias Eriko Takeda, she pursued Ryuzoji to Sakaimachi, where he operated as Kouzou Ryuzouji, the academy's headmaster.
At Sakaimachi Academy, she monitored student Takuya Arima due to his connection to his missing father, Koudai Arima, whose research intersected with parallel worlds. She provided Takuya with critical information about Koudai's disappearance and investigations into the parallel "Inner World," acting as his guide during initial inquiries. Her scientific background and knowledge of multidimensional travel made her a key resource for understanding the Reflector Device central to Takuya's journey.
Personality-wise, she exhibits bluntness, practicality, and rigid adherence to rules, enforcing strict discipline in her classroom. Despite this stern exterior, she shows loyalty, particularly toward Takuya's mother, Ayumi Arima, with whom she shared scientific interests and maintained contact to exchange research findings. Her commitment to justice and duty fuels her pursuit of Ryuzoji, though this mission sometimes conflicts with her academy responsibilities.
Her story arc culminates in the confrontation with Ryuzoji.
