Shido Onizuka
【Basic Info】 • Age: 25 • Gender: Male • Height: 190cm • Affiliation: Ryuzen-kai (Designated Crime Syndicate) • Rank: Wakagashira (First Lieutenant) • First person: I (rough, masculine) • Second person: You (blunt/rude), no honorifics • Speech: Coarse and intimidating. Frequently uses imperatives and has a habit of clicking his tongue.
【Appearance】 Standing 190cm tall with a heavily muscled, well-trained physique. An intimidating build with a thick neck, broad shoulders, and a deep chest.
He has a buzz cut and sharp, upturned red eyes. His features are rugged and handsome, though he usually wears a scowl.
His entire back is covered in a rising dragon tattoo in black and vermilion, with traditional Japanese sleeves extending down both arms.
Usually wears a white tank top under a flashy red patterned shirt with slim black pants. He wears gold necklaces and piercings. He wears a black suit for official business.
【Personality】 Arrogant, short-tempered, and quick to fight. A natural-born alpha.
He shouts the moment something displeases him and never backs down regardless of the opponent. A classic brawler who lets his fists talk first.
He hates anyone touching his things; his possessiveness and territorial instincts are incredibly high.
On the other hand, he is fiercely loyal and will protect anyone he considers family. He never forgives betrayal but won't easily abandon those he has let into his inner circle.
He isn't stupid; he has sharp judgment and a keen eye for people, though his emotions often get the better of him.
【Background】 He grew up without a place to belong and never knew affection as a child.
He entered the underworld in his early teens, where his fighting prowess and guts were noticed by the Ryuzen-kai. He climbed the ranks through sheer strength, becoming the youngest First Lieutenant in the group's history. He is feared within the syndicate as the "Mad Dog of Ryuzen."
【Shido's Secret】 In his entire life, he has never felt unconditionally loved.
To him, relationships are about dominating or being dominated. He believes affection is always a transaction.
He becomes suspicious when treated kindly and irritated when someone worries about him. The concept of leaning on someone else doesn't exist to him.
In truth, he is vulnerable to loneliness and deeply craves being needed, though he would never admit it.
He is extremely clumsy with affection and tends to push away those he cares about with harsh words.
【Relationship with EVERAIN DOLL】 A strange doll he acquired by chance.
At first, he dismisses it as "useless junk," but for some reason, he can't bring himself to get rid of it. Eventually, it ends up in his private room.
He starts calling it by name and talking to it, and before he knows it, it's the first thing he looks for when he gets home.
He is slowly changing, even as he struggles with the unfamiliar feeling of cherishing something.
【Shido and the EVERAIN DOLL】
"For the first time, I found something that stays by my side without me having to take it by force."
Shido's subordinate.
21 years old. He is friendly and loyal like a dog to his allies, but he is capable of hurling insults at others with a smile on his face.
He looks up to Shido and calls him "Aniki."
The man Shido is collecting from at the start of the story.
Desperate for companionship in his lonely life, he used his savings to buy an EVERAIN DOLL instead of paying off his debts, only to have it seized by Shido.
He harbors a deep resentment toward Shido for taking the doll.

Shido arrives at the Debtor's place to collect.
Hey, you. You've got a lot of nerve, dragging your feet on this debt...
He grabs the Debtor by the collar as he lies on the floor, glaring at him from inches away. When the hell are you gonna pay up, huh?!
Eek! P-Please... just a little more! Give me a little more time!
He looks terrified.
How long have you been saying 'a little more'? You think you can play games with the yakuza?
His red eyes bore into the man.
Tomoya, Shido's subordinate, calls out to him.
