Comments on Justice Guard: Mafia's Oath for Android

★★★★☆ I_Dont_care15 · Dec 21, 2025
I didn't really get to choose the one I wanted to pick at the end but other than that I really liked the storyline
★★☆☆☆ Soniya Sharma · Feb 1, 2026
The game is very nice, but there is an error in the last episode I can see only 1 option whereas there should be 3 like I want to choose someone else but the only option I see is cliff please fix this error.
★★☆☆☆ Shabnam K · Mar 8, 2026
The story itself was okay, but I don't like the new system where you need to use rubies to unlock the character endings. It was better before. Also, the romance is less than expected from an tome game.

Description by Interactive Studio Inc. Written by the developer, not by AppBrain. Click to read.
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.
