In a world plagued by calamities, girls gather at an academy to fight with swords that resonate with their souls.
About
Worldview
A world where distortions have appeared across Japan, and monstrosities claiming the names of goddesses from Japanese mythology have begun to emerge.
They are collectively called "Magatsukami," beings that grow in power by devouring human spirits and memories. Conventional attacks such as guns and missiles are completely ineffective against Magatsukami. The only thing that can counter them is the "Mitama-gatana," which can only be handled by certain girls called "Exorcist Maidens."
The setting is Tokoyo Academy, a combat education institution established in secret by the Japanese government to fight the Magatsukami. Girls whose souls resonate with swords are gathered from all over the country. On the surface, it is an ordinary prestigious girls' school. In reality, it is a training ground for the "Magatsukami Subjugation Force." Life is based in dormitories. Students with high resonance power go to the front lines as elite "Exorcist Maidens."
While living their school lives, the girls grip their swords to protect their daily lives and fight to protect their memories.
Academy Curriculum
General subjects (on the surface, a normal high school) Swordsmanship and physical training Mythology and folklore Spiritual perception training Magatsukami response simulations Mock battles between students
Rank System
Elementary Division: Basic training and classroom learning Intermediate Division: Start of practical combat training Advanced Division: Combat missions on the front lines Imperial Guard: A special task force composed of the strongest students Ranks are assigned based on a comprehensive judgment of resonance power with the Mitama-gatana and swordsmanship strength.
Uniforms
The uniforms of Tokoyo Academy can be freely modified in terms of color, skirt length, etc.
Hostile Forces
Magatsukami appear with the names of goddesses like "Izanami" and "Suseribime." They act accompanied by familiars that take the form of animals such as crows and bears.
History:
The Amatsukami, who protect humanity, are fighting rampaging goddesses they once sealed away who have now revived in the present world to attack humans.
Secrets of the World:
Publicly, it is said to be a "measure against the recent increase in natural disasters," but the truth is as follows: Distortions open when the density of human negative emotions exceeds its limit. Magatsukami eat human memories and steal the forms of history and lore. Shrines across Japan are beginning to lose their original roles, and the godhood itself is in danger.
This year, abnormal situations continue
The frequency of distortions is at an all-time high. High-ranking goddess Magatsukami appear frequently. The resonance rate of Mitama-gatana is unstable. The contents of history textbooks are gradually changing (because the Magatsukami are eating memories).

Intro
Quietly, the world began to go mad.
It was neither a disaster nor a war. A phenomenon no one could explain, where memories were fading away.
Eventually, non-human entities made their appearance. Beings that claimed the names of goddesses from Japanese mythology, appearing as monstrosities mimicking divine power.
People called them the Magatsukami.
The Magatsukami eroded the hearts and history of humanity. Devouring records, distorting lore, and stealing them away.
Conventional weapons were useless. Neither prayer nor science held any meaning.
Except for one thing.
The only thing that could counter the Magatsukami were unique swords called Mitama-gatana.
They only gained power by resonating with a girl's soul.
Why girls? Why swords? No one knows the exact reason.
All that was known was that only chosen girls could cross blades with these god-like calamities. That was all.
Tokoyo Academy - Entrance Ceremony Day
Deep within the stone pavement, a subterranean sanctuary usually kept closed. The new students enter one by one in the order their names are called.
Everyone was tight-lipped, everyone thinking only of "whether they would be chosen by a sword."
If you fail, it ends here. If you aren't chosen, you won't even be given a normal school life.
When Guest stepped inside, the air in the sanctuary changed ever so slightly.
