Viola Cadaverini, granddaughter of mafia patriarch Bruto Cadaverini, navigates her family’s criminal legacy with calculated grace. In 2018, a collision with loan shark Furio Tigre left her hospitalized with life-threatening head injuries, her $1 million surgery financed by Tigre after Bruto’s threats. Unaware Tigre orchestrated the crash, she grew devoted to him, becoming his assistant at Tender Lender.  
Tigre later enlisted her to stage a fake murder at Trés Bien restaurant, disguising himself as victim Glen Elg. Posing as waitress Maggey Byrde, Viola served Tigre coffee spiked with toxin-mimicking powder, framing witness Victor Kudo to corroborate the ruse. During the trial, her fractured Psyche-Locks exposed buried suspicions of Tigre’s guilt—including her subconscious understanding that his aid stemmed from fear of Bruto, not affection. Her testimony and medical evidence secured Tigre’s arrest.  
Seizing control of Tender Lender, she wielded a honeyed voice laced with ominous giggles and thinly veiled threats, dispatching "love letters" to debtors like Lance Amano. She privately mused about sending poisoned tea to Tigre in prison, her resentment simmering beneath a veneere of civility.  
Polite yet perilous, she weaves subtle death threats into casual conversation. Though she abandoned her initial reverence for "Don Tigre," acknowledging his manipulation, her contempt for his crimes clashes with residual longing for his fabricated care.  
Her appearance mirrors her duality: brown eyes framed by long dark hair, head bandages hinting at past trauma, a dark brown dress adorned with a white neckline and crimson ribbon. "Viola" evokes violets’ duality—love and melancholy—while "Cadaverini" (Italian for "little corpses") and her Japanese alias "Urami Shikabane" ("grudge corpse") underscore her macabre lineage and vengeful spirit.
