In this order:

Takagi - Cyborg Model HFC120781x of the Nova Hunters. One of the most well-built Nova Hunter Cyborg Models of the squadron. His primary weapon is the Magnum Blade, an energy revolver with beam sword capabilities. He and his "brother" are the only two that have mastered the gunblade style.

Shin - Cyborg Model HFC120681x of the Nova Hunters. Takagi's "brother." He was activated one day before Takagi was. He and Takagi are the highest-ranked Nova Hunters.

Jeremy - A smooth criminal that joins Takagi's party in the first chapter. He uses two "out of date" handguns - these still use copper bullets instead of rechargable batteries for energy blasts.

Alexa - A friendly girl who is also a silent assassin. She also joins Takagi's party in the first chapter, but later on. Her primary weapon is a sword that can break into two. She takes the sword apart for quick strikes and puts them together for strong slashes.

More to come later.
