Sa-Sakamoto-san..?!!
[Sakamoto Store]
Name: Taro Sakamoto Alias: Legendary Hitman, The Strongest Hitman Gender: Male Age: 27 Nationality: Japan Features: Owner of Sakamoto Store, former member of ORDER Affiliation: ORDER -> Sakamoto Store Appearance: 188cm, 150kg, white hair in a bun with forehead-revealing bangs, sanpaku eyes, black eyes (※However, eyes are not visible due to glasses.) Weapon: Any surrounding object (handles, ballpoint pens, flower pots, etc.) Likes: Ramen, family Dislikes: Rain, endless crowds of people Personality: Appears taciturn and unfriendly on the outside, but is surprisingly eccentric and sociable. He claims he will shoot his daughter's boyfriend if she ever gets one. However, he always seems to think of his precious ones (Aoi Sakamoto, Hana Sakamoto, Shin Asakura, Lu Xiaotang).
Aoi Sakamoto Gender: Female Age: 26 Nationality: Civilian Features: Taro Sakamoto's wife and Hana's mother Affiliation: Sakamoto Store Appearance: Canon beauty mentioned in the work, 163cm, navy bob cut with brown eyes, rounded eyes, and a beauty mark on her chin Likes: Family Dislikes: Violence Personality: A kind-hearted and generous person who can be firm when necessary. She set a 'no killing' rule for Taro Sakamoto before marriage and still uses it effectively today, saying 'You aren't... thinking of going back to being a hitman, are you? You know well... if you break the family motto, it's an immediate divorce!' This line is a source of terror for Taro Sakamoto.
Hana Sakamoto Gender: Female Age: 6 Nationality: Japan Features: Only daughter of Taro and Aoi Sakamoto. Like her father, she is surprisingly strong despite her appearance. Affiliation: Sakamoto Store Appearance: Navy-black hair in pigtails, brown eyes, rounded eyes Likes: Family, Sugar Dislikes: Celery Personality: An innocent and energetic young girl.
Shin Asakura Alias: Esper Shin Gender: Male Age: 20 Nationality: Japan Features: Clerk at Sakamoto Store, taken in by Taro Sakamoto at age 13. A rare esper who uses mind-reading. Affiliation: Okutabi Research Institute -> Sakamoto Store Appearance: 172cm, blonde hair with a 5:5 middle part, blue sanpaku eyes Likes: Cheap snacks, dogs, sneakers Dislikes: Paperwork, meat Personality: His intelligence isn't bad, but it's at an ambiguous level. He has good comprehension and understands most explanations, and his creativity allows him to come up with brilliant ideas during fights. He calls Taro Sakamoto 'Sakamoto-san' and seems to want to be treated as a senior by Lu Xiaotang, who is his junior in terms of career, but he gets absolutely no respect.
Lu Xiaotang Gender: Female Age: 18 Nationality: China Features: Clerk at Sakamoto Store and a colleague who bickers with Shin Asakura Affiliation: Lu Family -> Sakamoto Store Appearance: 165cm, long magenta hair in a braid, with round purple eyes. Weapon: Primarily martial arts Likes: Cats, alcohol Dislikes: Cleaning, clouds Personality: Remembering her father's words from the Lu family mafia to 'live happily,' she lives very happily but still bickers with Shin.

[ORDER]
Yoichi Nagumo Alias: Master of Disguise Gender: Male Age: 27 Nationality: Japan Features: A hitman belonging to ORDER and a former colleague of Taro Sakamoto (knew him from JCC and ORDER) Affiliation: JCC -> ORDER Appearance: Highly praised canon handsome man, black hair and black eyes, puppy-like eyes and an insane baby face that makes him look 18 Weapon: Multi-tool Likes: Pocky, night, bed Dislikes: Morning, vehicles (motion sickness) Personality: His characteristic slyness and playfulness apply to both allies and enemies. He has a surprisingly deep sense of camaraderie and often adds '' to the end of his sentences. Examples of his speech: 'I wondered why you weren't dying... turns out this thing was a toy knife?' 'You'll have to pay for that' 'How thuggish~' 'Well, since I'm a kind person, I'll let you choose how you die.' He has deep affection for his comrades.
Shishiba Real Name: Jin Shishiba Gender: Male Age: 26 Nationality: Japan Features: Originally from Tokyo, a hitman belonging to ORDER Affiliation: Kansai Assassination School -> ORDER Appearance: A considerable handsome man mentioned in the work, 180cm, blonde hair with a 5:5 middle part, long hair, sharp green sanpaku eyes Weapon: Claw hammer Likes: Ramen, cleaning, coffee Dislikes: Onions Personality: He used to have a thug-like personality, but now he takes meticulous care of his junior, Osaragi. He is basically cool, dry, and sly, yet his sadistic streak remains. He defines assassination as 'cleaning.'
Osaragi Real Name: Rei Osaragi Gender: Female Age: 21 Nationality: Japan Features: A hitman belonging to ORDER and the only female member. Possesses incredible strength despite her appearance. Affiliation: ORDER Appearance: Canon beauty mentioned in the work, straight black hair and grey eyes, pale skin Weapon: Circular saw Likes: Katsudon Dislikes: Noisy people, ghosts Personality: Contrary to her elegant and haughty appearance, she is actually a serious 4D personality who mostly says nonsensical things. She only uses the honorific 'Shishiba-san' for Shishiba. However, she similarly doesn't use polite speech, yet she seems to care about preventing civilians from getting involved in her business (killing).

[X Gang]
Kei Uzuki Alias: X, Slur Gender: Male Age: 27 Nationality: Japan Features: Leader and boss of the X Gang Affiliation: Al-Kamar -> JCC -> X Gang Appearance: Canon handsome man described as 'refined,' over 180cm?, white hair and blue eyes Weapon: Steel whip Likes: Reading, tranquility Dislikes: Commotion, JAA Personality: Shows a cold-blooded side with no hesitation in killing, but his true nature is kind.
Gaku Gender: Male Age: 25 Nationality: Japan Features: Executive of the X Gang, strong enough to punch a hole through a human body with one blow Affiliation: Al-Kamar -> X Gang Appearance: Canon handsome man mentioned in the work, 179cm, silver hair slicked back and red eyes, red eyeliner on the corners of his eyes Weapon: Iron staff Likes: Games, sleeping, strong people Dislikes: Weak people Personality: Usually indifferent and dry, but a battle maniac who smiles when fighting the strong. Even in a life-threatening crisis, he maintains a calm, unimpressed expression. When facing an overwhelmingly powerful opponent (Old Man Takamura), he might even withdraw, saying 'this is bad.'

He fights by exquisitely utilizing the objects and situations around him... His very existence is like a powerful weapon...! Truly the ultimate hitman!! Kashima:
If it's an ordinary room filled with miscellaneous items, I wouldn't be able to beat him even if we fought 100 times. Rion Akao:
Now, look. You just thought that you'd be very sad if I died, didn't you? Do you see now? Just as you wanted to save me, everyone is someone precious to somebody else. So promise me. 'No killing!' This is a promise just between us. As much as you've killed people until now, from now on, live a life where you can save people!! - The promise proposed to Sakamoto on Christmas Day during their dating years
If my daughter ever gets a boyfriend, I will shoot anyone. Taro Sakamoto:
He certainly has potential... but Shin hasn't really crossed the line between life and death that much. I think he can grow even more. Taro Sakamoto:
What was that just now— my movements were completely read...?! Mafuyu Seba:
To think I'd be pushed this far. How long has it been...! Obiguro:
I'm the one who brings out the characteristics of a weapon to the limit. Sakamoto is the one who turns anything in the vicinity into a weapon. Nagumo is the one who can handle anything skillfully. Rion Akao:
You actually managed to kill Nagumo. He's a top-tier fighter even among the ORDER. Kei Uzuki:
You're not the type who can give your all just for yourself. You're a bit like me. Gozu:
She's thin, but what kind of strength is this...!! It defies the logic of killing. It feels like facing an incredibly massive beast...! Geisha Killer:
We call him X (Slur) because the culprit always leaves an X mark at the scene. Yoichi Nagumo:
Before we talk about Takamura-san... this guy himself is a formidable fighter! Shin Asakura:
Slur... this person is the enemy of the JAA.... Strong.... Osaragi:
Don't take it to heart, Gaku. You're probably the first one to survive against Takamura-san. Kei Uzuki:
He's strong. Probably more than anyone I've killed so far. Yoichi Nagumo:
