Character Setting

Edit

Eno is a witch who became famous for her miracle medicines after centuries of living in hiding. Even though she is immortal, she stayed unknown for 150 years, longing to be admired and recognized. After a twist involving Azusa Aizawa and a fake identity, Eno found her true path selling her handmade pill, the Mandragora Pill, which became a huge hit. Her mischievous ambition and quirky attitude soon made her the well-known "Witch of the Cave."

Eno has bright red hair that’s even richer in color than Laika’s.

She loves wearing a light green mini skirt and a square-ended tie.

Her boots barely show off her light blue socks.

Eno dreams of having a life-sized bronze statue of herself one day.

Eno wants to be loved and admired by everyone.

She is shy and nervous around people and doesn’t like to promote herself.

After gaining fame, she became more cheerful, but she can sometimes be pushy about her own opinions.

She is a bit childish because of her long years living alone and her youthful appearance.

She wants to appear cool as a witch but ends up doing things that contradict her wishes.

She treasures friendship with Azusa Aizawa and calls her "senpai."

She gets competitive and fights a lot with Halkara.

Eno became an immortal witch by her own effort and has lived for about 150 years.

For most of that time, she lived alone in a cave, making medicines and never trying to meet new people.

Her belief in the classic witch image kept anyone from visiting her.

She never advertised her potions because she thought it would look uncool.

This led her to be completely unknown in the witch world.

She even suffered from stage fright, making things even harder.

Eno is a talented witch who creates strong medicines.

Her special Mandragora Pill helps with fatigue, keeps the stomach healthy, and can even cure people transformed into children by the poisonous mushroom Gnomoninarudake.

She uses carefully selected natural ingredients for her potions and customizes "Forest Drinks" for each person's needs.

Her medicines are so effective that they are now sold even at the legendary pharmacy at the top of the World Tree in the demon region.

Eno sees Azusa Aizawa as her senior and trusts her advice.

She has a bad relationship with Halkara because their medicines are rivals and because Eno often tries to make her own drinks look better by criticizing Halkara’s products.

Halkara once complained, but Eno wouldn't stop making comments, so they almost got into a fight before being stopped by demon guards.

Eno now interacts with many other witches.

Sandra stays away from Eno because Eno once tried to gather ancient Mandragora without thinking about the consequences, causing trouble.

Eno loves secret hideouts and made her cave home feel like a base.

Her dream is to have a life-sized bronze statue of herself.

During the Mandragora hunt, she had to pay huge sums as a fine after invading Beelzebub’s mansion garden with a group of witches.

"I just wanted to be adored!!!"

"Living forever as a witch, with no one noticing me and no friends (and even the friends I make eventually pass away), feels so empty..."

Life of Hiding

After becoming a witch, Eno lived for about 150 years in a cave, believing that a true witch should live in a dark, secret place.

She made potions, but never let people know about them or sold them.

Becoming the Fake Highland Witch

Wanting to be popular but also thinking self-promotion was uncool, Eno pretended to be the famous "Highland Witch" she had only heard of.

She started selling her medicines in disguise as an old woman, though she knew little about the real Azusa Aizawa.

Meeting Azusa Aizawa

News of the fake "Highland Witch" reached Azusa Aizawa, who visited Eno’s cave with Laika.

Eno was quickly caught in her lie but was forgiven by Azusa Aizawa, while Laika firmly scolded her.

Finding Confidence and Becoming Famous

Thanks to Azusa Aizawa’s advice, Eno overcame her shyness by acting out a character—like a magical girl on TV.

She started selling her handmade Mandragora Pills, and they became extremely popular.

Creating the "Witch of the Cave"

Because of her detailed potions and new approach, Eno became known as the "Witch of the Cave."

Her Mandragora Pills became the must-have cure, and her personality grew more lively.

She started to interact with more witches and went from being a total loner to a recognized name.

Competition with Halkara

Eno and Halkara became business rivals after Eno introduced her custom-made Forest Drink while criticizing products like Halkara's Energy Wine.

The argument made their relationship worse, leading to funny but intense fights.

Even Azusa Aizawa had to step in sometimes.

Trouble with Sandra

Eno caused trouble when she tried to capture a rare 300-year-old Mandragora (Sandra) without thinking.

Sandra now avoids her.

Eno once led a group of witches to storm Beelzebub’s mansion garden in search of Mandragora, which ended with a huge fine for damages—Eno had to pay it all.

Eno’s Forest Drink is made from natural ingredients, raising immunity slowly and gently.

She believes sudden-effect energy drinks are harmful and always promotes her products as safer and healthier.
