Opening Words

Hello everyone, I never expected I would write a fanfic for Touhou with a certain amount of original world building that doesn't belong to Touhou lore but I decided to push my luck and try it for the first time to see how it's going.

Still, I hope my first try for a Touhou fanfic would give everyone a nice story to read. I hope you all enjoy it!

Because this story contains a certain amount of original world building along with OC characters acting as a main character so I would love to write out the list of trivia below in case you need to check for extra info

List of OC Characters in the story

-Vạn Thư (万書): A hermit librarian in Hakoniwa who escaped to Gensokyo. Her pen name was Chidori (千鳥), it was a fake name used by her for decades in Hakoniwa during the war.

-Sengi (千欺): A Shogun in Hakoniwa who became the new Emperor after the Warring State Era

-Iruka (海豚): Son of Sengi who became the new Emperor of Hakoniwa with a benevolent rule toward his people

-Naoki (直樹): A lazy logistic officer who once served Sengi before he became a rebel leader.

-Thiên Điểu (千鳥): A dummy decoy created by Vạn Thư who entered Gensokyo searching for her creator.

-Himari (陽葵): A kind and wealthy businesswomen at the Human Village in Gensokyo

-Legendary Crane: One of the founders of the Great Library of Hakoniwa

-Keihatsu (啓発): The previous librarian who was believed to be dead just as Vạn Thư but she survived the assassination attempt and began to search for the Fountain of Miracle to enhance herself at the cost of corrupting her mind by its power.

-Alternative Yukari Yakumo: A parallel version of Gensokyo's Yukari Yakumo, she is one of the founders of the Great Library of Hakoniwa who had been forgotten from the history after a failed power struggle against the Legendary Crane who erased her name from all of the historical records in Hakoniwa.

Major States in Hakoniwan Warring State Era

-Maruyama (円山): A state created by the Emperor loyalist who wanted to preserve power for the Emperor and dispose the power of the Shogun caste

-Raika (雷火): A state created by those who wished to keep the power for the Shogun caste and turn the Emperor into a ceremonial role

-Senka (千花): A state created by Shogun Sengi who turned the farmers into an army to defeat both side and claim the Emperor title for himself

Other Trivia

-Hakoniwa (箱庭): A name of nation inside a dimension far away from Gensokyo. It is also a name of that isolated dimension as well.

-Kotou (孤島): An isolated world which was meant to immigrate the Gods, magical creatures and other magical beings from Hakoniwa into this world under the creation of Alternative Yukari. It is similar to Gensokyo in a sense that those who ceased to exist in Hakoniwa would end up in Kotou and the boundary barrier created by her scroll would hide their existence from the people of Hakoniwa.

-Duality Brush: A magical ink brush from Vạn Thư that could create magical scroll or burn it. It's a symbol of creation and destruction.

-Memory Orb: An orb that could simulate the historical world based on the user's memory.

-Fountain of Miracle: A non-existent magical fountain in the legend that could bring any librarian back to full power.

List of scrolls in the story

Note: Every scroll inside the Great Library of Hakoniwa always has a false-safe mechanism where the user could chant to disable it even if they run out of magic. This was meant to deal with the situation where they run out of magic as the basic rule of creating or activating a scroll was to pay a certain amount of magic to use the scroll so it was inevitable that the user will eventually run out of magic.

+Scroll of Immortality: A scroll that granted the user the ability to become immortal.

+Scroll of Teleportation: A scroll that could teleport into a different world but its exact coordination is always unknown and it requires knowledge about the existence of the different world.

+Scroll of Dummy: A scroll that could spawn a dummy decoy with an imperfect mimic of the original user but their personality could develop on their own as time grew by.

+Scroll of Disguise: A scroll that allows the user to disguise as a different person including their identity. Because it only drain magic per cast it was easy to use it as the user could keep one fake identity for themselves for the rest of their life.

+Scroll of Illusionary Dimension: One of the most troublesome scrolls in Hakoniwa, this scroll was supposed to teleport people from various location into one desired location in Hakoniwa and people could exit at another location after the scroll duration ended or somebody disabled it. Yet it gone haywire and became totally chaotic then transported everyone randomly without any control.

+Scroll of Dimensional Barrier: A scroll created by Alternative Yukari Yakumo to prevent the other parallel Yukari from entering Hakoniwa including other beings from other dimensions who tried to enter Hakoniwa.

+Scroll of Thunder: A scroll that could conjure a violent thunderstorm by manipulating the weather.

+Scroll of Tsunami: A scroll which creates a massive tsunami that engulf everything below.
