Otome mafia romance with 3 men. Join the gang that guards the city.

Justice Guard: Mafia’s Oath is an otome visual novel romance with 3 love interests, where joining a mafia that protects the city brings you to the men who run it. ■ Story ■ You move to a new city and witness a rough-looking man about to cause trouble in a store. Before things escalate, the customers call for the “Justice Guard,” a local mafia that protects the town. The man leaves in frustration, and you learn that the city was once plagued by crime until a drifter named Ike formed the Justice Guard to keep order. Later you see that same man leading an attack on a defenseless customer. Unable to ignore it, you step in, taunt the attackers, and bring down their leader. As the remaining thugs prepare to retaliate, Calvin, the Justice Guard’s second-in-command, arrives and helps you fight them off. Impressed, you ask to join, and Calvin takes you to Ike. At the hideout, Ike’s charisma captivates you. When you say you want in, he accepts without hesitation ― they never turn away new members. Calvin assigns Cliff as your “big brother,” and Cliff challenges you to a fight. He underestimates you, and goes down fast. Pleased, Ike officially welcomes you into the Justice Guard. ■ Characters ■ Ike ― The Charismatic, Domineering Boss A mafia leader admired by many. He founded the Justice Guard to save the city, uniting criminals and the poor under his rule. Despite his standing, the townspeople respect and even idolize him. With the presence of a true leader, he rehabilitates those who join him, entrusts real work to his subordinates, and lets his own vulnerabilities show ― one of the reasons he is so admired. Calvin ― The Cool and Composed No. 2 Ike’s loyal right hand. Responsible and steadfast, he carries out Ike’s orders to the letter and takes pride in his role. Once feared as a lone mad dog, he found a new purpose after meeting Ike. Cliff ― The Little-Brother Newcomer A new recruit who deeply admires Ike. Weak in a fight and short on experience, he has a fierce sense of justice and cannot turn away from anyone in need. Frustrated by his own weakness, he trains tirelessly to grow stronger.
