Azusa Aizawa

Azusa Aizawa (アズサア・イザワ) is the main character and main heroine of Slime Taoshite 300-nen, Shiranai Uchi ni Level Max ni Nattemashita series. Previously a Japanese woman who died from overwork, she was reincarnated as an immortal Witch and proceeded to take life easy while killing slimes as a form of income. After 300 years however, her level becomes maxed out as a result and, consequently the most powerful being in the world, draws unwanted attention to her peaceful life.

Background
Azusa previously lived as a normal twenty-seven year old human on Earth, in Japan, as a "corporate wage slave," working long, consecutive hours at the expense of her personal life. This work ethic eventually resulted in her death, as one day she blacked out and awoke to the sight of an Angel. After pitying Azusa for her short life, the Angel promises to ensure Azusa's next life has the potential to bring her "sheer happiness," and allows her to make any prerequisite wish she wants for her next life.

Resurrected as an immortal Witch in the mountains, nearby the countryside town of Flatta, Azusa dedicates the next three hundred years to an easy life of hunting slimes and making potions.

Appearance
Since her reincarnation, Azusa takes on the appearance of a young European woman, roughly around the age of 17. She has long blonde hair, with some of it fashioned into a braid, and large blue eyes. Her primary outfit is her Witch's garments, comprising of a large, pointy hat, a black coat over a white blouse with a yellow cravat and a dark blue skirt.

On other occasions, Azusa's outfit will change to fit the situation; such as when she attended the Red Dragon wedding, she wore a tailored dress to the event, but she will, for the most part, wear her primary outfit.

In the light novel, it is unknown what Azusa looked like before she was reincarnated, with no descriptors during or after the introductory chapters to describe her, but It's likely that she was a typical Japanese woman in her previous life. In the manga however, she is depicted as an ordinary Japanese woman with long dark hair, though her face was not shown.

Personality
Azusa is generally characterised 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 slimes, though she still recognises 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, including characters that originally intended to kill her.
