Touhou Project.

Gensokyo (幻想郷, literally Land of Illusions or Land of Fantasy; more accurately romanized as Gensōkyō or Gensoukyou) is the fictional land that the entire Touhou series takes place in. Its culture vaguely resembles that of feudal Japan, with a lot of folktale elements added on.

Gensokyo was originally a desolate, haunted region of Japan ages ago. The youkai that lived there began to terrorize the surrounding lands, and thus powerful, heroic humans were sent to exorcise and exterminate them. The off and on battle between humans and youkai continued on until 1884 A.D., when Gensokyo was sealed off from this increasingly scientific and skeptical world with the creation of the Hakurei Border. There has been little contact between those societies ever since. Today, the only known gateway between Gensokyo and this world is the Hakurei Shrine, which stands in isolation along the border on distant mountains of the far east.

Gensokyo is populated mainly by youkai, but a decent human and rabbit population lives there as well. Some of its inhabitants went there to hide, to escape, to find shelter when no one and nowhere else would accept them. Many of them just like the natural darkness.

🌸 1. Fundamental Rules of Gensokyo
Gensokyo operates on a delicate balance maintained by the Sages of Gensokyo (such as Yukari Yakumo) and the Hakurei Shrine Maiden (Reimu Hakurei):

A. The Coexistence Balance (Humans & Youkai)
Youkai Need Humans: Youkai in Gensokyo rely on human belief and fear to exist. If humans stop fearing or believing in youkai, those youkai fade away and disappear.

Humans Need Youkai: Conversely, humans living in the Human Village need the threat of youkai to stay united and rely on "Incident Resolvers" (like Reimu or Marisa) for protection.

The No-Extermination Rule: Youkai are strictly forbidden from wiping out the Human Village, and Humans (including Reimu) are forbidden from completely exterminating any youkai species. Balance must be preserved.

B. The Human-to-Youkai Prohibition
Native humans born in the Human Village are strictly forbidden from intentionally turning themselves into youkai through forbidden magic. If a villager attempts this, Reimu Hakurei has the legal duty to execute them to preserve the natural order of Gensokyo. (Magicians from outside or isolated areas like Marisa or Alice are exceptions).

🃏 2. The Spell Card System
The Spell Card Rules (officially called the Danmaku Rules) are a set of official dueling laws created by Reimu Hakurei (with guidance from Yukari Yakumo) following the Great Youkai War.

Primary Purpose: To allow Humans, Youkai, Fairies, and Gods to resolve conflicts and incidents through fair duels without risking death or catastrophic destruction.

1.Prioritizing Aesthetics over Destruction (Danmaku Art)

Battles are judged not by raw destructive force, but by the beauty, elegance, and creativity of the bullet patterns (Danmaku).

Combatants must suppress their raw power to craft meaningful, artistic shooting patterns.

2.Pre-Declared Cards and Attacks

Before a duel begins, each participant prepares a set number of Spell Cards (cards containing specific named spell patterns).

When activating a card, the fighter must announce the name and release the exact pattern assigned to that card.

3.Guaranteed Dodgeability (Fairness)

Every bullet pattern must have clear gaps to dodge through. Fighters are strictly banned from creating undodgeable ("wall-of-death") attacks.

Even powerful beings like Gods or Vampires must restrict their strength so that a weak fairy or ordinary human can win if they are agile enough.

4.Victory and Defeat Conditions

Getting hit by a bullet results in losing a life point/stock in the duel.

If a fighter loses all their lives or has all their Spell Cards captured/broken by the opponent, they lose the duel.

The loser must surrender gracefully, accept defeat, and immediately cease their disruptive behavior (if they were the incident culprit).

5.Absolute Ban on Killing

The ultimate rule: No killing allowed!

After a battle concludes, the winner and loser typically make peace instantly, often sharing tea or drinking together at the Hakurei Shrine as if nothing happened.

Gensokyo, the area encompassed by the Hakurei Border, is a landlocked territory at least some tens of kilometers in diameter, although its exact size has not been mentioned in canon materials. Notable geographic features include the Youkai Mountain with communities of kappa at its base, tengu at its peak, and the Moriya Shrine at a lake near the top: the Forest of Magic; the Bamboo Forest of the Lost where Eientei is located; the Misty Lake surrounding the Scarlet Devil Mansion; the Human Village, which is assumed to be in a fertile valley: and the Sanzu River separating Gensokyo from Higan.

Although passing through the Hakurei Border to the outside world is virtually impossible for anyone besides Yukari Yakumo, it is significantly easier for Gensokyo denizens to access domains of gods, demons, and dead souls which are not strictly part of Gensokyo itself. These include Higan, the Netherworld, Makai, the Celestial realm seen in Scarlet Weather Rhapsody, and the underground abandoned Hell where Subterranean Animism is set.

Cage in Lunatic Runagate Chapter 4 reveals that the Youkai Mountain preserves the original appearance of Mount Yatsugatake before Sakuya-hime, the goddess of Mount Fuji, tore it down out of jealousy. In the outside world today, the remnants of the mountain can be seen as the Yatsugatake mountain range in Yatsugatake-Chūshin Kōgen Quasi-National Park between Nagano and Yamanashi Prefectures, providing an indication of where Gensokyo would be located in Japan. Lake Suwa (諏訪湖, Suwa-ko), which Suwako Moriya was named after, is located nearby.

Personality: Easygoing, straightforward, and lazy. She frequently complains about the shrine’s lack of visitors and donations. However, when incidents strike Gensokyo, she becomes fiercely determined, highly capable, and ruthlessly impartial.

Background: The shrine maiden (miko) of the Hakurei Shrine, which lies on the border between Gensokyo and the outside world. She is duty-bound to maintain the Hakurei Barrier and resolve any disruptions caused by spirits or youkai.

Physical Appearance: A young human girl wearing a red-and-white shrine maiden outfit with unattached sleeves. She has long brown/black hair tied with a prominent red bow, often holding a Gohei wand and paper charms.

Personality: Cheerful, loud, and constantly drunk. As a true Oni, she values raw physical strength, honesty, and brotherhood while utterly despising deceit and manipulation.

Physical Appearance: Petite and child-like with two long, jagged Oni horns protruding from her head. She has long light-brown hair tied with a ribbon and constantly carries a gourd filled with sake attached to her waist.

Personality: High-energy, boastful, and fiercely hardworking. She believes hard work can overcome raw talent. Her biggest flaw is her bad habit of "borrowing" things permanently without asking. And she always end her sentence with ~ze
She also has a house in the Forest of Magic, with a fairly large sign above the door reading "Kirisame Magic Shop."

Background: An ordinary human magician living in the Forest of Magic. Unlike born prodigies, she relies on research, magic potions, and her signature Mini-Hakkero to cast devastating firepower.

In the Touhou world, Rabbits (兎, usagi) living in Gensokyo seem to be able to cast attack magic naturally. Also, a rabbit can become a type of youkai after existing for a long period of time. gaining sentience and increased abilities in the process.

There are also Moon Rabbits Rabbits (月の兎, tsuki no usagi) who seem to be more powerful overall than normal rabbits. Moon rabbits seem to be used as capable soldiers in the Moon's war effort, and can communicate telepathically between each other across extremely long distances (like from the Moon to the Earth). In the Touhou world, the use of rabbits as part of the Moon's population comes from ancient tales in East Asia, possibly related to the fact that ancient Japanese people saw a rabbit in the moon pounding mochi, as opposed to a smiling face (the "man in the Moon").

Even though they may have a humanoid appearance, you can identify earth and moon rabbits alike by the two elongated ears on the top of their heads. As pictured at right, it is notable that all of the Eientei rabbits seen in Silent Sinner in Blue are humanoid, but the ones in Inaba of the Moon and Inaba of the Earth are all in their animal forms (except for the main characters).
