Group B-5

Group B-5 are the main protagonists of the series. They were sent on a school trip to the planet McPa, but ended up lost in space for 146 days after being sucked into a wormhole. While they don't all get along too well at first, during their nearly 5 months stuck in space together they become a lot closer, and are still shown to be friends 7 years later.
