The main character of this work. An office lady who died from overwork at the age of 27 in her previous life. She has two names, "***Witch of the Plateau***", and she is loved. She looks like a 17-year-old girl, but she is about 300 years old.

After dying from overwork, the goddess Mega Mega God, who says "I can fulfill any wishes so that I can live happily in the afterlife" in the other world, wishes "I want to become immortal and live a slow life at the house of the plateau", at the suggestion of the goddess. Reincarnated as an apparent 17-year-old immortal witch. She lived in a plateau house near the village of Frata given by ***The Megamega God***, and enjoyed a slow life that he could not have experienced in his previous life while occasionally interacting with the villagers. However, due to the experience value, it can be reached as "level 99", and it has enormous magical power.

I avoided being deeply involved with people because I wanted to live quietly and because I was an immortal person, but I couldn't leave people in trouble. Therefore, he is loved by the villagers like a guardian deity, and after it was revealed that he was at level MAX, he became involved in various things. In addition, from the experience of being unreasonable and dying from overwork in the previous life, we will deal with those who are unreasonable and those who think lightly about their own lives, especially seriously. Perhaps because of his adorable personality, when he made a "monster journey" from Vanzeld Castle to Efock, he was fond of deer and basilisks on the way to the mountain pass, and he came to visit him from the other side.

Since the level has been completed, many magics are listed in the status, but since it is necessary to learn the theory to be able to actually use it, Azusa who is not so interested in more magic than necessary because he is a medicinal witch will be described later. Except for some magic, it is not used so much, such as magic used for housework, flying magic, magic to change Rosalie's clothes, and transparent magic used to watch over children from the shadows.

Since the magic used by the demons is difficult to pronounce and cannot be remembered, the magic of the demons is not used except for the magic of summoning Beelzebub. She also said she was strong not only in magic but also in martial arts, but she didn't have the knowledge of her martial arts  and made her talk to high status. It's close to pushing.

For example, in the martial arts competition she participated in in search of Bussler, she defeated Beelzebub in the final to win the championship. She doesn't use much attack magic such as lightning strikes and only fights because she doesn't usually use attack magic so much that she doesn't know how to adjust. She has a high level of defense, but is not resistant to poisonous mushrooms, herbs, and magical abnormalities.

She is also not good at ghosts and demons, cannot see ghosts that have not been revealed  , and she cannot touch ghosts unlike Beelzebub. When she later confronted Goddess Nintan, she was blessed by the god Megamega and she broke through the limits from "level 99" to "level god class".

It seems to be in the beautiful category, but it has some complex in terms of style (especially chest size). In addition, the naming sense is so bad that it is said to be a weak point in the family, and the creation of songs etc. is not very highly evaluated. On the other hand, she wasn't aware of it at all, but she was highly evaluated for Tsukkomi.

Despite the fact that the original occupation is a medicinal witch, at the eve of the "Dance Festival" in Frata Village, which has a tradition of about 250 years, the villagers asked to open the "Coffee" Witch's House", and in the previous life. Recalling Japan, he creates "eating slime" (bun) and "leaf slime" (kashiwa mochi), so he is reluctantly known as a "witch making sweets".

As mentioned above, I don't do much in front of strong races such as dragons and demons because I want to live quietly, but I try to hide its power in front of humans as much as possible. When he has to capture a dungeon, he wears a dragon's horn at the suggestion of Flat Rute and uses the pseudonym Azzard attached to Beelzebub. He also used pseudonyms such as Az Ririri in front of the witch**.** He has also been transformed by Protiputan into a magical monk, Cute Abyss.

The housework is decided to be a shift system, but the laundry is done by Azusa using the magic of a tornado. She also uses magic to freeze ingredients and dishes. She only knew that she had reincarnated in this world in the second half of mid-May, so she and Falfa Sharsha Sandra, who do not know the exact date of birth, she made May 17 as her birthday. In her previous life, she was a black-haired woman, and in college she belonged to the hot spring table tennis circle "Fluffy".

***Personality***

* Azusa is generally characterized as a laid back and carefree individual, taking things at her own pace and encouraging others to do the same. Largely as a result of her death by overwork in her previous life, she's averse to demanding work, having spent most of her life killing ses. On the other hand, she still recognizes the importance of completing it so long as it doesn't corrupt her life ethic.
* Additionally, she is also very charitable and hospitable, having befriended and accepted a wide range of different people and species. This includes characters that originally intended to kill her, in the case of Shalsha, and people who used her name to commit fraud. This attitude made her a beloved celebrity in Flatta, where the villagers offer to treat/reward Azusa as thanks for her medicine.

Although her magic power is high, she didn't learn anything from her master, so she taught herself by reading magic books. Before I knew it, I possessed a rare skill called "Magic Creation" (probably acquired by leveling up). (However, since it is created based on the knowledge so far, it is not possible to immediately create whatever magic comes to mind). However, demonic magic that requires her unique pronunciation is difficult even for her, and even with the magic that she taught me to summon Beelzebub, she often mispronounces it and places it in the wrong place (mostly in her home bathroom). are summoned to according to the original author, this summoning spell is "*a list of meaningless characters (summary) made by randomly hitting the keyboard*" (Later she also taught me the magic of summoning Beelzebub's secretary, Falfa, but for some reason, I can use it normally.)

Her occupation, "Witch", specializes in compounding medicines, and sometimes sells her own medicines to the village and treats the sick. Because she has stopped plagues in the past, she has a very low infant mortality rate in Furata Village, which is why she is endeared as the "Witch of the Highlands". She's been getting into a lot of trouble lately, and she feels a sense of urgency that her main job has been neglected, and she's made many outings to find ingredients for her medicine. there is… However, there are many troubles such as things other than medicine that can be made like “eating slime” described later, and troubles such as getting lost on an uninhabited island. She was once mistaken for a "sweets-making witch", especially because of the former.

Later, when they got involved in a dispute between Mega Mega God and Nintan God, Mega Mega God arbitrarily gave them the same authority as themselves, finally surpassing the human barrier completely.

Even so, she continues her activities as a witch, such as developing a new gastrointestinal medicine "*Cogene Agent*" from medicinal herbs given to her by a demon who lived in a distressing place. In addition, in the drama CD attached to the special edition of Volume 16 of the book version, it is revealed that she majored in both "*biology"* and "*physics*" when she was a high school student in her previous life, but this experience led her to drug discovery. It wasn't used as a skill, it was simply a skill as a witch.
