Eriko Takeda

Eriko Takeda stands out with her body-hugging outfit and a mini skirt, topped with a white lab coat.

She ties up her long, unruly hair, and her bangs usually hide her eyes.

Her three sizes are 96-60-87 centimeters.

For her birthday, she was born on July 7th.

In the remake, her outfit was updated and her casual look sometimes includes sunglasses.

Eriko has a cool and practical personality with little sign of a domestic lifestyle.

She openly smokes even at school, showing a rebellious and self-confident side.

Despite her straightforward attitude, she listens to troubled students like Takuya Arima and offers advice.

These actions make her respected and admired among students.

She claims to have come from Europe just two months before the story begins.

Her behavior is mysterious, like sleeping under the infirmary bed and sneaking around the samurai mansion at night.

She often ventures into town in flashy clothes to secretly investigate people like Kouzou Ryuuzouji.

She is especially interested in rumors about curses and events that involve Ryuuzouji.

Eriko is smart, very observant, and resourceful.

She is skilled at gathering information without drawing attention.

She is also a heavy smoker and is not embarrassed to smoke even when students are around.

She is the school doctor and the homeroom teacher to Takuya Arima and his classmates.

She keeps a close watch on Takuya, offering guidance when he is troubled.

At one point, she even comforts Takuya in a special way after he is hurt by Mitsuki Ichijou and Kouzou Ryuuzouji’s relationship.

Her actions suggest she cares for her students but stays mysterious about her true motives.

The death of a man named Abel, who appears in Mitsuki's dreams, deeply motivates her actions.

In the adult anime version, Kouzou Ryuuzouji’s absence makes Eriko’s purpose seem less clear.

Her real identity as a dimension inspector is not revealed until much later in the story.

She seems to know that Takuya Arima can travel between parallel worlds, though it’s never explained how.

Early Actions and Investigation

Eriko Takeda first appears as the mysterious new school doctor, surprising everyone with her modern, bold fashion and smoking habit.

She investigates rumors of curses at the old samurai mansion and probes into Kouzou Ryuuzouji’s activities.

Secret Origins Revealed

As the story goes on, especially in Mitsuki Ichijou’s route, it is revealed that Eriko actually comes from another dimension.

She is a dimension inspector with the real name "Eiric Quadro" (the name is difficult to pronounce due to her home world's complex language).

Her mission is to track down a vengeful spirit, which has taken over Kouzou Ryuuzouji’s body.

Connection to Abel

It is revealed that this spirit once belonged to Abel, Eriko’s lost lover from her own dimension.

The spirit had taken Abel’s body, caused his death, and became Eriko’s greatest enemy.

Eriko’s pursuit of this spirit is the true reason she travels to the world of Takuya Arima.

Life in the Academy

During her time at Sakai Town Academy, she mixes into everyday life while investigating.

She becomes involved in several students' lives, giving advice and even lending emotional support when needed.

Eriko continues her mission while hiding her true identity until the events of the "Other World" chapter.

Eriko always maintains an air of mystery, even among other adults at the academy.

In adaptations, her personality, look, and mysterious background tend to stay the same, except for changes in her costume style.
