Nanahoshi Shizuka

Nanahoshi Shizuka (七星ナナホシ 静シズ 香カ) is one of the people Rudeus saved from being hit by a truck in his previous life. However, in that moment, she was transported to this world some time after Rudeus, resulting in the Teleport Incident. Afterward, she was taken in by Orsted and eventually became a successful entrepreneur whilst searching for a way back to Earth.

Appearance
Nanahoshi is a Japanese teenage girl with long black hair, described as being above average in appearance. She's more often seen wearing a white mask without any particular characteristics.

Personality
Due to her desire to go back home and her unattached attitude to the Human World, she tends to like being alone. She's serious when working and enthusiastic when it come to stuff from her old world. Before meeting Rudeus, she spent all her time indoors and didn't like meeting people as she didn't want to grow attached to anyone in the world. Additionally, she maintained low contact to avoid the possibility of contracting unknown pathogens, and uses that to justify her isolation.

Background
She was saved by Rudeus in his former life's final moments and was teleported to the Human World later known as the Teleport Incident. She met Orsted and with his help she learned the Human God language, gained knowledge about the Asura Kingdom and was able to meet Perugius. Using Orsted's power she became rich by making trade routes, so she could gain enough influence to search for her friends, and develop a way to return home.

Plot
She was first introduced in volume 6 of the LN/WN accompanying Orsted when they encountered Dead End on their journey to the Fittoa Region. After Orsted nearly killed Rudeus, she told Orsted to spare Rudeus' life and so Orsted casted healing magic on him.

Nanahoshi meets with Rudeus once again at Ranoa Magic Academy where she establishes herself as a Class A Mage because of the sweeping changes she introduced in the Academy and is also a Special Student. After giving an explanation of her intentions, Nanahoshi, Rudeus and Sylphiette begin researching on the cause of the Teleport Incident.

Nanahoshi is among the guests who attends Rudeus and Syphiette's wedding and for helping with her research on Summoning Magic, Nanahoshi allows Rudeus and his friends to accompany her when she goes to meet Perugius in his Sky Castle.

Power and Abilities
Nanahoshi has no magic power due to being from another world where magic didn't exist. This means she can't use magic or wear battle aura, though she can still use Magic Items, which work with their own Magic Power.

For some reason, her body does not age; her hair never grows longer, and her nails keep the same length regardless of how much time passes, yet she still needs to consume food and pass waste, and could still get sick. Nanahoshi suspects that it's because she's from the future, or a different world.

It is shown that she is a very skilled negotiator and businesswoman, enabling her to setup many systems that monetize her knowledge from earth. As a result, she has multiple streams of income that make her very wealthy, allowing her to focus on her research. She also holds influential positions in several organizations and is Rank A among the Magic Guild because of her accomplishments and contributions.

Due to her training from Perugius, she has extensive knowledge in summoning and teleportation magic, having studied it as part of her research to go back to her and Rudeus' original world.

Equipment
Nanahoshi possesses three magic rings seen in her right hand. First worn in the index finger, through unknown means, prevents magic from working near the caster as shown when Sylphiette failed to cast attack magic on her. The second worn in the middle finger, creates an invisible barrier in front of her as seen when Sylphiette tried to punch her. The third worn on the ring finger, allows Orsted to know her location using a compass, when infused with magic.

Achievements
Achieved Rank A in the Magic Guild

Quotes

 * To Rudeus: “I was probably summoned to this world in order to create a method for your descendants to kill the Human God in the future. That’s why, as long as I don’t create that method, I won’t be able to return to my original world. My return magic will fail.”

Etymology

 * Nanahoshi means "seven" (七) (nana) and "star" (星) (hoshi).
 * Shizuka means "quiet" (静) (shizu) and "fragrance, fragrant" (香) (ka).

Trivia

 * Nanahoshi has a disease called Drain Syndrome. It's a condition that occurs when a human with little or no magical power naturally accumulates magical power over time, until their body begins to react negatively to it. Because of this, she must regularly drink tea made from Sokasu Grass, which will alleviate her condition by releasing the accumulated Magical Power through her waste. However this does not cure her condition, as she must continue to drink the tea from Sokasu Grass.
 * In the redundancy chapters, Zanoba and Rudeus created an automaton modelled after Nanahoshi. It was almost identical to her except for the hair length, completed with even the naughty bits. It was created without Nanahoshi knowledge and consent, and later named "Une".
