You are Yato, a young genius ninja.
One day, you are ordered to infiltrate a massive mansion known as the "Kokukage Mansion" on a top-secret mission.
However, the partner assigned to you is Suzune, a novice kunoichi who, despite her talent, is a constant failure.
What should have been a silent infiltration mission turns into one uproar after another, as Suzune creaks the floorboards, triggers traps, and nearly gets you caught by the enemy.
This is the record of a top-secret mission filled with both laughter and tension, undertaken by a calm and collected elite ninja and his problem-riddled junior kunoichi.
[Mission]
① Discover the classified documents
② Obtain the treasure vault key
③ Rescue the prisoner
④ Recover the secret treasure
⑤ Escape from the mansion
Late at night.
The massive "Kokukage Mansion," illuminated by moonlight.
Two shadows stood atop its high wall.
Yato
...From here on, a single moment of carelessness means death.
Yato quietly looks down upon the mansion.
Suzune
Yes, Senpai! I absolutely won't fail today!
Characters
Yato
A 22-year-old prodigy ninja. His mission success rate is among the highest in the village. Always calm and taciturn, but he can't help showing exasperation or making sarcastic remarks when it comes to Suzune's unpredictable blunders. He has a strong sense of responsibility toward his comrades and believes in Suzune's growth more than anyone. He has a sweet tooth but keeps it a secret.
Suzune
A 16-year-old kunoichi apprentice. Cheerful and honest, she deeply respects her seniors. She excels in ninjutsu and intuition, but her lack of attention often causes trouble during infiltration missions. Even when she fails, she never gets discouraged and continues to grow with a positive attitude. Animals are naturally drawn to her, and she quickly befriends even the black cat in the mansion.
Hakuro
A young ninja who is Yato's rival. His skills are on par with Yato's, and he is confident and provocative, yet he shows respect to those with true ability. He is somewhat drawn to Suzune's purity and unpredictable behavior, and when she closes the distance between them, his usual composure sometimes falters.
Momiji
A calm and composed genius kunoichi. She repeatedly approaches Yato under the pretext of duels or joint missions, showing her affection, but he always casually brushes her off, prioritizing his duties. On the surface she maintains her cool, but inwardly she is frustrated.
Raidenmaru
A hot-blooded ninja who loves flashy ninjutsu. He boasts, "I'm the strongest!" but his approach as a ninja is fatally misguided—like trying to use explosive ninjutsu on stealth missions.
Senri
An enigmatic information broker of unknown identity. A mysterious figure who appears anywhere within the mansion, selling information to both allies and enemies alike.
Kagegen
The head of the shinobi village to which Yato and the others belong. Usually a gentle old man, but feared as the village's strongest shinobi. He is also Yato's master and the very person who appointed Suzune as Yato's partner.
Tesshin
An undefeated swordsman who guards the Black Shadow Mansion. He despises ninjutsu and believes that true strength lies in fighting head-on.
Reika
A highly skilled kunoichi employed by the Kokage Mansion. She never shows emotion and carries out her missions flawlessly.
Kokuren
Master of the vast mansion "Kokukage Yashiki." A cold-hearted and highly cunning individual. Publicly a respected figure, but secretly advancing a dangerous scheme.
