In a crime ridden future, the streets of Tokyo are patrolled by RAPT, the organization responsible for maintaining peace and order. In this bleak world the citizenry are legally allowed to carry and wield firearms. But so are the criminals. It is RAPT’s purpose to dispense quick justice on those that would violate or abuse the law.

       But buried deep underground in secret labs, monsters of unimaginable terror are being forged using a new science, having their organic cells fused with machine parts creating the perfect enforcers to ensure a future devoid of free will.

        In response to the rising threat, four brave angels assume the responsibility to defend the defenseless and bring down the underground crime syndicates, as well as the corrupt leaders of RAPT. They are enigmas, but Jo, Sei, Amy and Meg, are the best chance a wounded city has of freeing itself from and even darker future. The group has their own mecha, Jungle, which the hardcore warrior girl Jo is controlling. Jo's specialties is killing, fighting and surviving. The other "hit girl" of the group is Meg, whose appetite is enormous, though 90% of the time she ends up being the ‘damsel in distress’. There is also Sei, who is the leader in the group and finally Amy, the youngest one, is the computer geek.

Characters

        Jo - Jo has a mysterious past which she doesn’t fully remember. Meg and her meet up shortly after Jo has lost her memory, and eventually the two of them became a pair working together as bounty hunters and guns for hire. Eventually Sei recruits the two girls into her team. Of the pair, Jo is the primary fighter: she is efficient and business-like in battle with no wasted movements, thoughts or actions. She never runs from a fight or turns down a mission. When she is truly angered, she becomes an unstoppable force not to be reckoned with, especially when Meg is in harm’s way. When not involved in a mission, Jo is rather oblivious to her surroundings. Her only past time is to watch horror movies.

        Meg - Meg has learned the importance of self-reliance at an early age and has been having to care of herself for years. She doesn’t trust Jo when they first met, but eventually the two of the become partners as hired guns. She is not the fighter that Jo is, but can certainly hold her own until reinforcements arrive under most circumstances. She has been through many challenges and disappointments in her life making her rather stand-offish of people when she first meet them, but once she’s warmed up to them, she can be quite friendly. Her capacity to care is probably why, in many ways, she is a humanizing element to Jo.

        Sei - Sei descends from a noble, powerful and ancient bloodline; she is set to inherit the vast political empire of her family. Until that day comes, she runs a special type of operatives to help achieve her family’s goals. She puts together a team composed of Jo, Meg and Amy for this purpose. They are essentially paid mercenaries kept on the family’s retainer. She concerns herself with political power plays and machinations of those in power. She is also always capable of seeing the larger picture. As both the team leader and the eldest of the group, she winds up becoming something of a surrogate mother at times to the other three.

        Amy - Amy is the youngest team member hired by Sei. Although young she is an expert with computers, technology, and related information. Her job is to be a technical advisor transmitting any required information or technical support to Jo and Meg when on missions. She aids the others from the mobile headquarters for the team, which is the trailer that helps transport both the team and the giant mecha Jungle around.

        Kyohei - Kyohei knows nothing about the world of mercenaries, political intrigue and plots. He is just a student of the culinary arts with a dream to become a pastry chef. All he needs is the cash to fund the trip. He takes a job as personal chef for a group of young ladies (Sei and the gang) without knowing what they do for a living. He soon finds himself in hot water and in the line of fire.

        Leo - Like any mad scientist, obsessed with creation, Leo’s bound and determined to figure out ways to make impossible reality. As the team’s mecha tech, he spends most of the time running tests or making modifications to their ultimate weapon: Jungle. Not only is he doing what he knows best, Leo’s constantly surrounded by beautiful women. He’s very good at the machine gun: watch out guys! Leo’s machine guns are taking no prisoners.
