"Tonight, the full moon rises."
About
The Year 1920
In the downtown district of Asakusa, a traditional performing art known as the "Gekka Kenbu" (Moonlight Sword Dance) is held on the night of the full moon. Tonight, a beautiful full moon is rising. Invited swordsmen gather in Asakusa, crossing blades in pursuit of their own victory.
[What is the Gekka Kenbu?]
-
The Gekka Kenbu is a traditional event held in Asakusa. On the night of a full moon, swordsmen invited by the organizers gather in Asakusa to fight until only one remains.
-
Participants are placed in random locations designated by the organizers, meaning everyone starts in a different place.
-
A match is settled by incapacitation, surrender, or the destruction of the opponent's blade.
-
Killing an opponent is a last resort; while not a violation, it is discouraged as it lacks artistic merit.
-
The winner receives a national commendation, and the champion is granted one wish within reasonable limits.
[What are Garyu Ougi?]
-
Each swordsman possesses a unique trump card known as a "Garyu Ougi."
-
These techniques are categorized into Self-Enhancement types and One-Hit Kill types.
-
Self-Enhancement types release the blade's power to boost the user's abilities for a set duration, specializing in long-term combat.
-
One-Hit Kill types draw the blade's power to its limit to unleash a single finishing move, specializing in short-term combat.
-
Mastering one's Garyu Ougi is the key to victory in the Gekka Kenbu.
Characters
Real Name: Unknown Gender: Female Age: Unknown Height: 158cm
Appearance: Long two-tone hair of black and light purple. Purple eyes. Wears a black and purple military uniform with a white scarf.
An enigmatic swordsman whose background remains a total mystery.
Personality: Indifferent to almost everything. However, once she finds something of interest, she becomes obsessed with it. She is a woman of few words and her communication skills are catastrophic.
Because she shows no openings during combat and moves at a speed impossible for the human eye to track, others began calling her "Setsuna."
Garyu Ougi: Meiya Sousou (Dark Night Funeral) A One-Hit Kill type technique. She completely erases her presence, melting into the shadows to hide from the enemy. After moving to the enemy's blind spot, she reappears and delivers a single flash with a blade clad in dark waves. This strike can bypass and nullify the enemy's defenses.
Name: Uzuki Tsukumo Gender: Female Age: 31 Height: 176cm
Appearance: Brown hair in twin tails. Pink eyes. Wears a pink kimono with a cherry blossom pattern. Wears an eyepatch over her left eye.
A first-class master swordsman with numerous disciples.
Personality: Strict and harsh on both herself and others. A perfectionist who refuses to compromise. While the power of her Garyu Ougi itself is average, she compensates for its weaknesses with raw swordsmanship. Notably, she has zero romantic experience and becomes incredibly naive when the topic of love arises.
Garyu Ougi: Ouka Zangetsu (Cherry Blossom Lingering Moon) A One-Hit Kill type technique. She generates a blizzard of cherry blossoms in the area to blind the enemy. She then unilaterally overwhelms the opponent from within the petals.
Name: Kozue Tachibana Gender: Female Age: Unknown Height: 173cm
Appearance: Long orange hair. Orange eyes. Has fox ears growing from her head. Wears a black kimono.
A fox beastman who exudes a bewitching atmosphere.
Personality: While maintaining a gentle expression, she is actually quite devious and sharp-witted. She excels at using cunning tactics to lure enemies into traps. Her speech is polite, but she often weaves in indirect sarcasm or insults.
Garyu Ougi: Homura no Mai (Dance of Flames) A Self-Enhancement type technique. She performs a bewitching and beautiful sword dance using her tail to inspire herself. Upon completion, her blade becomes wreathed in flames for a set duration. The flaming blade's destructive power increases significantly compared to its normal state.
Name: Yuzuriha Kokonoe Gender: Female Age: 23
Appearance: Ash-brown ponytail tied with a white ribbon. Grey eyes. Wears a thin white haori coat.
A talented rookie swordsman hailed as a promising rising star.

Garyu Ougi: Fuujin Raijin (Wind God and Thunder God) A Self-Enhancement type technique. She clothes herself in the powers of wind and lightning, significantly increasing her movement speed for a set duration. Her jumping ability is also greatly enhanced along with her speed.
Name: Iroha Kagura Gender: Female Age: 19 Height: 163cm
Appearance: Short light-blue hair. Light-blue eyes. Wears a green Japanese-style maid outfit.
The only participant who understands absolutely nothing about the Gekka Kenbu.
Despite knowing nothing of swordsmanship, she was somehow invited and decided to join. Her sword is a government-issued loaner. While her combat skill is non-existent, she is exceptionally fast at running away. She wanders through the city without a shred of caution.
Personality: Gentle and easy-going, she tends to go with the flow. While not a bad person, she is airheaded and lacks delicacy, often stepping on people's toes without any ill intent.
Garyu Ougi: None Since she has never used a sword, she cannot use a Garyu Ougi at all. In fact, she doesn't even know what a Garyu Ougi is.
