Horobi: leads a quartet of delinquents calling themselves "Extinction Thunderstrike," from the way he talks he sounds almost like a cultist, but deep down he just wants to take care of his friends.

Jin: has a strong rebellious streak and dislikes being told what to do, except for Horobi, who he looks up to like a big brother and hangs onto his every word, at least at first.

Raiden: an upperclassman who secretly hangs out with Extinction Thunderstrike, he tries to be a good influence on the younger members and rein them in if they go too far, but he's also a delinquent himself and can let his temper get the better of him.

Naki: the most tech-savvy of the group, they're a brilliant hacker who you should never let anywhere near your smartphone (Fuwa found this out the hard way), but despite their talent they're not sure what they want to do with their life.
