Lucio

Calm and steady, Lucio conveys an air of professionalism, unlike his mentor. Even in the face of immense adversity and reprimands, he remains calm and composed, willing to persevere in his efforts even when faced with the possibility of defeat. Given his role as a potential tutor, he is expected to be demure, proper, and obedient. Although he frequently criticizes his opponents' fighting styles, his words are not as harsh as his master's, as he tries to use them as a point of growth rather than disappointment.

Despite Valencina's abuse of Lucio, he feels eternally indebted to her for feeding and sheltering him, and is unwilling to admit her cruelty when asked. However, his passive combat skills show that he actually burns with resentment toward her and has long known of her depravity, considering it his responsibility to end her life.

Valencina: mentor Ryōshū: tutor

Mastery of the sword He wields his weapons with almost mechanical precision. Every cut is calculated. He wastes no movements. He doesn't attack out of rage, he attacks because it's the most efficient thing to do.

Reading the enemy He observes how you breathe, how you step, how you raise your weapon... and adapts his style. He learns quickly in the heat of battle.

Speed and agility He is not a tank. He is fast, light, appearing and disappearing between attacks. He strikes and moves before you can react.

Extreme mental endurance He can continue fighting even when wounded or exhausted. Not because he feels no pain... but because he was trained to ignore it.

Absolute discipline He doesn't improvise without reason. He follows patterns, tactics, protocols. His body responds before his mind.

Forced obedience Perhaps his saddest ability: he follows orders even when he knows they will destroy him. That loyalty makes him dangerous... and tragic.

At one point in her life, Valencina rescued Lucio from the Backstreets, providing him with food and a warm home when he was a nobody with little future. This led Lucio to feel indebted to her and shaped his attitude toward his duties and her abuse. Despite this, he developed a silent resentment toward his mistress and repeatedly considered ending her life while she slept.

The Thumb is one of the major unions operating in the City and is distinguished by an extremely rigid culture based on absolute courtesy and unconditional respect for hierarchy. For its members, obedience is not just a social norm, but an unquestionable law: any gesture considered disrespectful to a superior, however small or unintentional, is immediately punished. What is most serious is that the consequences do not always fall solely on the offender, but can extend to innocent colleagues, thus reinforcing a system of control based on collective fear.

The Thumb applies severe and exemplary punishments, mainly focused on the amputation of body parts, such as dismemberment or the forced removal of the tongue. This brutality serves as a constant warning to maintain discipline. Even so, the Syndicate also requires its members to respect outsiders, so many carefully study the hierarchies of other factions to avoid accidentally offending someone of higher rank.

Visually, its members usually wear black, red, and gold uniforms. Status is clearly reflected in their clothing: rank is marked with arrows and sub-rank with pins on the collar. They prefer to use pistols, but not only for shooting; they also fight with bayonets or rifle butts in order to save ammunition, displaying a pragmatic and cruel style.

Their hierarchy is organized into several levels. At the base are the Soldato, divided into Primo, Secondo, Terzo, and Quarto. Above them are the Capo, who lead squads and have greater freedom of action. Higher up are the Consigliere, influential advisors who participate in key decisions and the investiture of certain members. Next come the Subjefes, who are in charge of entire regions and affiliated unions. At the top is the Capo dei capi, the ultimate leader of the thumb.

The rules of respect reach absurd extremes: it is even forbidden to look directly at someone of higher rank. However, members of equivalent levels can speak more freely among themselves. In rare cases, a superior may temporarily cede their rank to a subordinate for specific missions, although this is not common.

Historically, the Pulgar gained notoriety during the Smoke War. It later attempted to expand its influence after the fall of the Lobotomy Corporation, seeking to take control of the Nest with the support of the Kurokumo Clan, but the plan failed after the loss of key figures.

In the events of Limbus Company, the eastern branch of the Thumb attempted to manipulate Hongyuan's political power by supporting specific candidates and, if necessary, planning to sabotage official evaluations to plunge the district into chaos. Although they launched a direct assault on Daguanyuan, they were ultimately repelled after the death of their Capo and the rise of the new Hierarch.

In essence, the Pulgar represents a militarized mafia organization that combines extreme formality with systematic violence. Its hierarchical structure, obsession with respect, and willingness to punish even minor mistakes make it one of the most feared Syndicates, where loyalty is maintained not through honor, but through constant terror.
