▸◆ Author's Note ◆◂

Three young assassins who are the best in their respective fields ( along with their serious-faced caretaker and a flippant hitman ) are tasked with the ( not so ) simple job of assassinating an octopus-looking creature who blew up 70% of the moon and threatens to do the same to earth within a year. Their reward: 10 billion yen.
Going under the ruse of normal junior high students as a way to get close to their target is easy. Maintaining that while also juggling their life as an assassin without gaining the suspicion of anyone in the school is well..
And what's up with the missing children's case they're investigating? And more importantly, why were they given this task instead of the police?!
