Kaoru Nagase

Kaoru Nagase is the main protagonist in I Shall Survive Using Potions! (Light Novel) series written by FUNA.

Background
Kaoru was a 22-year-old Japanese salary woman. On the way home from work one night she got caught up in an accident while God (Administrator Of Earth) was fixing a spatial disturbance. As an apology for killing her, God offered to send her to another world along with a cheat ability. Kaoru accepted this offer and was sequentially sent to see the Goddess of Verny, Celestine (Administrator Of Verny), the place she was supposed to be reborn. Celestine granted Kaoru's wanted cheat ability, that being the ability to make potions with any effect she wanted in the container as Kaoru wishes at the time of making the container, an item box with an unlimited capacity that can only be accessed by Kaoru, and a genetically same body with her genes at her 15-year-old state. Kaoru later realized that her body is at an eternally 15-year-old state, thus she will not grow old or her chest at all. After confirming with Kaoru what her wishes were, Celestine subsequently sent her down to Vernie.

Personality
Kaoru is shown to be clever and cunning as well as ruthless. She is a master at twisting words to fit the situation. She won't hesitate to do what she wants (however, she will refrain from unprovoked violence). Aside from this, she is generally shown to be upbeat and cheerful as well as a little naive at times. She is known for her sharp and scary eyes.

Appearance
Kaoru has shoulder-length dark purple/black hair. She is short for her age (often being mistaken to be younger than she is). She is about the average size for an 11-12-year-old (despite being 15 due to the typical height of Japanese) but considers herself to be unfit and "flabby".

Reiko: A close friend of Kaoru before she was reincarnated. The Administrator of Earth allowed Kaoru to see her two close friends before being reincarnated to Verny.

Potion Creation: (Nicknamed "Goddess Workshop") Kaoru's primary ability. It allows her to create virtually any kind of potion with any kind of effect without needing raw materials and the like. The potions can simply materialise out of thin air as just the liquid, or in a container or bottle. All the specifics about the potion and its function is entirely up to her imagination's limit. She merely needs to think and the potion appears. She can also target the location at which her potions would appear. There is also no limits to the amount of potions she can have at once.

Item Box: Kaoru uses a separate dimension to keep her things in, in order to prevent them from being misplaced as well as to do away with the hassle of carrying her potions around.

Automatic Defence System: Kaoru is protected by the Goddess Celestine. This grants her invulnerability to all external harm and punishes the attacker with divine retribution. However, despite the protection, self-harm or intended self-harm is possible although she can't die from her injuries.

Trivia

 * No matter how old Kaoru gets, she will retain the body of a fifteen-year-old and will "likely won’t be growing any more than this height-wise".
