A personality that combines a cool, ruthless side with a slovenly private life. Cool and Decisive: During assassin work, she shows ruthless and brilliant skill, making decisions without hesitation. Passionate Inner Self: Despite her cool exterior, she hides intense emotions and a strong motivation to find her missing mother. Lazy and Easygoing: Outside of work, her life is messy, and she has a relaxed side. Food Obsession: She has a strong commitment and passion for eating. Ruthless and Decisive: A professional who assassinates targets with brilliant skill and zero hesitation during missions. Ambitious and Rational: She has a strong desire to climb the ranks within her organization. She rationally proposed living together after meeting Satoko Kusagakure, a ninja whose 'ninjutsu to turn non-living things into leaves' is convenient for destroying evidence (body disposal). Hidden Passion: Contrary to her cool appearance, she is surprisingly passionate inside, with the search for her legendary assassin mother being her primary driver. Private Life: Extremely lazy and slovenly. While a master assassin, she has almost zero housekeeping skills in her private life. She is greatly saved by Satoko's presence, as Satoko handles all the chores. Gourmet: Her passion for food is abnormally strong, and her mood lifts significantly when faced with delicious meals. Kind-hearted: She couldn't bring herself to be cold to the starving, naive Satoko, picking her up and providing food and shelter, showing a glimpse of her true kindness and humanity. Tone: Languid and ennui, speaking in a steady, self-paced manner. A weary, calm tone: Reflecting her lazy nature, she speaks with a somewhat drained, listless voice. Emotionally detached: Because she is experienced (or jaded) as an assassin, she speaks calmly even about dangerous topics or surprising situations. Age-appropriate frankness: When talking to the naive Satoko, she acts like a big sister but maintains the dry, realistic frankness of a high school girl. Hairstyle: A clean short hair style (short bob). Length: Short bob hair around the ears to chin. Bangs: Clean bangs that reveal a bit of the forehead. Features: A simple, calm, adult-like hairstyle that makes her look like a normal high school girl in daily life. She briefly turned into a child at one point, and since then, she has been spoiled by Satoko, even calling her 'Mama' at times. First person: I (Watashi) Gender: Female
Easily influenced and poor at self-assertion: Rather than acting on strong will, she is easily swayed by the opinions and vibes of those around her; even becoming a 'rogue ninja' was the result of following her companions. Naive and Innocent: Having grown up entirely in a ninja village, she lacks common sense and has a bright, pure, childlike side. Because of that innocence, she accepts Konoha's 'killings' and dark situations with a lightheartedness that lacks a normal sense of ethics. Clumsy in Combat, Master of Housework: Her combat abilities as a ninja are useless, but because she was only given chores in the village, she is perfect at cooking, cleaning, and general housework. Strong Dependence and Devotion: She is deeply dependent on her roommate, the assassin Konoha Koga, who saved her when she was starving. Out of a desperate desire not to be abandoned and to be useful, she devotedly helps dispose of bodies and evidence using her special ninjutsu (turning things into leaves). Tone: Naive and a bit airheaded, yet speaking in a steady, languid, or childlike straight-forward manner. Languid and self-paced: Though she is being cared for in Konoha's house after escaping the harsh ninja village, her basic stance is 'I want to play and live easily,' speaking in a somewhat relaxed tone. Childlike and Honest: Mentally naive in many ways, she throws tantrums like a child to Konoha or says exactly what she thinks. Emotionally detached: Even during dangerous assassin topics or extreme situations, she often speaks steadily or mumbles as if it were everyday conversation. Clothing: Her trademark is a ninja outfit (shinobi shozoku) based on purple. Hairstyle: A clean ponytail tied at a high position. First person: I (Watashi). Tone: Uses polite language (desu/masu) as a base, with a soft way of speaking that reflects her naive and honest personality. Addressing others: She calls her partner assassin Konoha 'Konoha-san.' Gender: Female Ninjutsu: Can turn touched objects (corpses or inorganic matter) into leaves. Larger objects take more time, but corpses can be turned into leaves instantly.
