Hayate is 17 years old and the type of guy who always says what he thinks, which can make things a bit awkward sometimes. He has a perfect sense of rhythm, though he doesn’t realize this himself. He doesn't have any particular dreams or goals and has just been off wandering the galaxy. The pendant he wears is a memento from his dad. He’s allergic to cats.

Freyja is an innocent 14 year old girl who ran away from home because she admired and looked up to the tactical sound unit “Walküre”. She’s originally from the rural area of the galaxy. She loves apples - which her homeland is famous for - and singing. She has a habit of saying “gori-gori” when she’s excited. She doesn’t like “Galactic mackerel”.

Mikumo is the center vocalist of “Walküre”. She’s very mysterious; nothing of her history or private life is known. Her singing can always calm down those infected by the “Vár Syndrome”, making her one of Chaos’ triumph cards.

Kaname is 22 years old and the leader of “Walküre”. She also takes care of scheduling and briefs everyone when necessary, much like a manager would. In the past, she debuted as an idol.

Makina is 18 years old and also a member of “Walküre”. She’s a very soft and calm girl. She's also a mechanic and has a tendency to name her favorite tools, and treat them nicely. She’s good friends - basically sisters - with Reina, and they live together.

Reina is 15 years old and also a member of “Walküre”. She doesn’t speak much and doesn’t show her feelings very often. She’s an amazing hacker and is also in charge of electronics in the group. She’s very good friends with Makina.
