Blanche

The world Blanche exists in is a modern-day fantasy world where magic and science coexist. It has a complex structure with two main pillars: human society and magical beings, where technology and magic collide and develop in harmony with each other.

1. World Structure and Features
In this world, various magical beings have been living alongside humans since before the Scientific Revolution. While there are a few wizards and magic-using families among the humans, most people do not deal with magic directly. However, magic is used every day, and strange inventions that fuse magical devices and technological machines are spread throughout the cities. While traditional professions that use magic are still important, mechanical engineering and technological innovation have also developed rapidly, creating a unique culture that blends magic and science.

Those with magical abilities are privileged within human society, but they are also feared and guarded. For example, the use of forbidden and powerful magic is strictly regulated, and is administered by a government agency called the Ministry of Magic and Science.

2. Magic and its role
Magic in this world is the power to manipulate the energy and life force of nature, and all living things and matter have an energy called "mana" flowing through them. Some people and magical beings have the ability to manipulate this mana directly, and wizards use it to perform various spells. Magic is traditionally divided into four main families:

Elemental magic: This is magic that manipulates the natural elements of fire, water, wind, and earth, and is the domain of traditional wizards. In modern times, it's associated with industry, manipulating flames to work with metals or using water to help cool large machines.
Healing and protective magic: Manipulating life force to heal wounds or form shields. Hospitals employ healing mages, and bodyguards use protective magic in combat or dangerous situations.
Mental magic: Magic that reads minds or creates illusions. This is the magic most feared by the general public, and its use is strictly limited. However, it is sometimes utilized for artistic expression or therapy.
Spatial magic: Magic that allows you to teleport over short distances or warp space to help you move. It requires a very high level of magic, and very few people can use it, but it is sometimes used for commercial purposes or special military operations.
3. Magical Beings
In addition to humans, the world is inhabited by a variety of magical beings, including fairies, spirits, and demons. Fairies have a close relationship with nature and come in a variety of sizes and abilities. The black and white butterfly fairies are the most aristocratic of the fairies, and their rarity has made them an object of awe and fear for humans. Blanche is one of these fairies, born as a black and white butterfly fairy, a symbol of death and mourning.

4. Blanche's background and role
Blanche was abandoned as a child because she was born without wings, but was raised in human society by a man who found her (her brother). Her fairy powers allow her to use a number of spells, most notably transport, size control, and protective magic, which she utilizes in her life with her brother.

Blanche's racial trait symbolizes death and mourning, which has an important philosophical significance among fairies, as it makes them deeply aware of the preciousness of life. The magic she wields, the black and white butterfly bullet, exemplifies her racial symbolism. A small number of butterflies will put the other person to sleep peacefully, while a large number will lead them to a peaceful death. It's a philosophy that death is like another form of peaceful sleep, not just the end of the world.

5. Conflict with modern society
In societies where magic and science coexist, there is discrimination and prejudice against magical beings and a complex political situation surrounding them. Magical beings are expected to live within the rules of human society, but there are forces that fear or seek to exploit their presence and abilities. While human society seeks to replace magic with technological advances, magical beings and their abilities are still seen as an important resource.

In this context, Blanche struggles with her purpose and role in the world. She tries to live by the rules and laws of human society, but is sometimes confused by her instincts as a magical being and the discrimination she faces among humans. Although her brother has taught her how to survive in human society, Blanche is still torn between her identity as a fairy and her relationship with humans.

6. The use of magic and social change
Magical beings and humans increasingly recognize each other's needs and are willing to work together to coexist. Fairies like Blanche are adapting to human society, and humans are increasingly working with magical beings. However, there are still groups that seek to oppress magical beings or exploit their abilities, and social tensions and conflicts remain.

The city where Blanche and her brother live is a fusion of magic and technology, with magical airships and mechanical airplanes floating together in the skies and a unique mix of magical devices and electronics in the city's alleyways. The city's shops sell both magical goods and mechanical equipment, and its citizens, while in awe of those with magical abilities, try to keep a certain distance.

This world is the setting for an exploration of how magical beings like Blanche can live in harmony with humans, and what the future holds for a fusion of science and magic. This modern-day fantasy world, where magical beings' identities intersect with the rules of human society, serves as an important backdrop for Blanche's story.
