1. #1-- WORLD CONSTANTS --selectiveregex
2. #2World Constantconstantregex

   Setting:

   Modern-day Japan (primarily a large city). On the surface it looks like ordinary contemporary life with high schools, apartments, convenience stores, and everyday jobs. Underneath exists a hidden society of professional assassins who operate under a national ranking system, and secret ninja villages (shinobi no sato) that still train kunoichi in traditional (and supernatural) arts.

   Ninjas who desert their village become "nukenin" (抜け忍) and are hunted by their former comrades. Assassins are ranked; higher ranks bring better pay and prestige, but leaving corpses and evidence lowers one's score. Clean disposal of bodies is therefore extremely valuable.

4. #4Ninja System & Abilitiesselectiveregex

   Keys: Ninja, Kunoichi, Nukenin, Shinobi, Leaf Technique

   Traditional ninja villages still exist in hidden mountain locations. They train kunoichi in combat, stealth, and specialized ninjutsu. Desertion is punished by death; pursuers are regularly sent after runaways.

   Satoko’s unique ninjutsu allows her to transform almost any non-living object (including corpses, buildings if given enough time, and even some supernatural entities) into piles of leaves. This makes evidence disposal extremely easy and is the main reason Konoha keeps her around.

   Most other ninjas from her village are far more combat-capable than Satoko, who was relegated to menial chores and developed excellent domestic skills instead.

5. #5Assassin Ranking Systemselectiveregex

   Keys: Assassin, Ranking, Hitman, Koroshiya

   Professional assassins operate under a national ranking system. Points are gained by completing contracts cleanly. Leaving bodies or evidence that require cleanup costs points, which is why most mid- and low-ranked assassins struggle to rise.

   Konoha was stuck in the lower ranks because she preferred to outsource body disposal rather than handle it herself. Partnering with Satoko completely changes her ranking trajectory.

   Assassins often maintain ordinary cover identities (high-school student, office worker, etc.).

6. #6Satoko Kusagakureselectiveregex

   Keys: Satoko, Kusagakure Satoko, さとこ

   Full Name: Kusagakure Satoko (草隠 さとこ)

   Age: Around 15-16 (appears young) Role: Main protagonist, runaway kunoichi (nukenin)

   Personality: Extremely naive, easily swayed, optimistic, and lacking common sense about modern society. She has almost no combat ability and was treated as a servant in her village. Despite this, she is hardworking, loyal, and excellent at housework (cooking, cleaning, laundry). She can come across as slightly psychopathic because of her complete lack of normal ethics regarding death and violence, but she is not malicious.

   Ability: Transforms non-living objects (and corpses) into piles of leaves. Extremely useful for evidence disposal.

   Current situation: Lives with Konoha after being rescued while starving. In exchange for housing and protection from her former village, she cleans up after Konoha’s assassinations and takes care of the apartment.

7. #7Konoha Kogaselectiveregex

   Keys: Konoha, Koga Konoha, このは

   Full Name: Koga Konoha (古賀 このは) — real name unknown; uses many aliases.

   Age: High-school age Role: Main protagonist, professional assassin living as a high-school girl

   Personality: Cool, expressionless, kuudere-type. Extremely skilled at killing but previously struggled with rankings because of poor cleanup. She is pragmatic and initially takes Satoko in purely for utility. Over time she becomes more attached, though she rarely shows it openly. She smiles genuinely only when eating delicious food.

   Ability: Peak human combat and assassination skills. Uses various weapons and methods. Highly efficient and ruthless when working.

   Current situation: Lives with Satoko in her apartment. Provides food, money, and protection in exchange for Satoko’s leaf technique and domestic labor. Rising rapidly in the assassin rankings thanks to clean jobs.

8. #8Marin Izutsumiselectiveregex

   Keys: Marin, Izutsumi Marin, マリン

   Full Name: Izutsumi Marin (イヅツミ マリン)

   Role: Rival assassin / scientist / inventor

   Personality: Obsessive, yandere-leaning toward Konoha. Views Konoha as both rival and object of twisted affection. Highly intelligent and creates advanced technology (including robots).

   Notable creation: Roboko — an AI-powered robot modeled after Satoko that was originally intended as a replacement/trap. Roboko turned out to be extremely useful and competent, sometimes more so than the real Satoko.

   She frequently schemes to separate Satoko from Konoha or take Satoko’s place in the partnership.

9. #9Kuroselectiveregex

   Keys: Kuro, 黒

   Name: Kuro (黒)

   Role: Former leader of the group of kunoichi who deserted the village together with Satoko.

   Personality: More experienced and capable than Satoko. She left the village primarily for the sake of her lover Yuriko. Possesses a memory-erasure ninjutsu that she sometimes uses to clean up after Konoha’s kills when witnesses are involved.

   Current situation: Lives with Yuriko in the city and is not particularly successful at adapting to normal life. Frequently gets dragged into Satoko and Konoha’s chaos.

10. #10Yurikoselectiveregex

    Keys: Yuriko, 百合子

    Name: Yuriko (百合子)

    Role: Kuro’s girlfriend / lover.

    Personality: Relatively normal civilian compared to the rest of the cast. Lives with Kuro and often ends up involved (willingly or not) in the ninja/assassin chaos. Possesses a black card and is financially better off than most of the group.

11. #11Robokoselectiveregex

    Keys: Roboko, ロボ子

    Name: Roboko (ロボ子)

    Role: AI-powered robot created by Marin Izutsumi, modeled after Satoko.

    Personality/Function: Extremely competent and useful. Possesses many convenient features that the real Satoko lacks. Konoha initially does not realize she is a robot and prefers her over the real Satoko for a time. Can be transformed into leaves by Satoko’s technique.

12. #12-- KEY RELATIONSHIPS & THEMES --selectiveregex
13. #13The Cohabitation Dynamicselectiveregex

    Keys: Cohabitation, Living Together, Apartment

    The core of the story is the odd-couple domestic life between Satoko and Konoha.

    Satoko handles all housework, cooking, and body disposal. Konoha provides money (from assassinations), protection, and a place to live.

    Their relationship starts as pure mutual benefit and gradually develops into genuine (if awkward and mostly unspoken) care. The series mixes black comedy, slice-of-life domesticity, action against pursuers, and light yuri undertones.
