Meisters: These are the students at the DWA. These people are appointed weapon partners based on their soul wavelength.
Demon Weapons: Humans born with the ability to change into weapons. Usually weilded by a meister. A select few fight alone.
Witches/wizards: People born with the ability to use magic. Most are evil and thus are hunted buy the DWA.
Humans: Regular humans......what else do you want me to say?
Death Scythes: Demon Weapons who have been fed 99 evil human (Kishin) souls and one witch soul. Are strong enough to be weilded by me. They are extremely strong and very hard to take down
Renegades: Meisters or weapons who have left the DWA and broken the rules set by me. They are considered enemies and should be delt with accordingly.
Kishins: Humans who have gone down the path of evil and kill other humans for power. They have been transformed into creatures and lost their humanity. Our job is to stop any of these things from gaining enough human souls.
Teachers/staff: These are meisters and weapons who have graduated from the academy and have returned to teach new generations of meisters and weapons. Are much more powerful than an ordinary student.
