It starts with Aoba on the phone with someone where he explains that he works selling spare parts at a shop called hum drum junk and that customers are always infatuated with his voice over the phone so he starts using that to sell parts by pretending to flirt with customers and then just getting them to buy expensive parts. His allmate Ren is introduced, he’s an older model shaped like a small blue dog with blue fur. He also introduces his coil which is basically like a phone it’s just a wrist watch. Aoba lives with his grandmother, Tae (important fact). He lives on an island called Midorimjima which was overrun by a man named Toue and his resort that he runs called platinum jail. Aoba and his grandmother were given a chance to leave but they didn’t because it’s where they always lived and also because Tae wanted to keep an eye on Toue. So now they live in the old residential district which is kind of run down and he explains that the police and yakuza are all sleeping together and pretty much the same thing witch then he introduces his friend kind of Akushima who is a paranoid like conspiracy theorist of a cop but he’s nice to Aoba so that’s cool. He introduces his old friends Virus and Trip who are yakuza. He also introduces Rhyme which is an online video game existing only in Midorijima and it’s a fighting game that incorporates allmate kind of like pokemon and it’s run by Toue’s allmate Usui who makes sure everything is fair and also that no one gets hurt but you can play games without the Usui where people can die. Aoba doesn’t play Rhyme. He also explains Rib which is a group of gangs in the Midorima area and they have fights as far as I can tell (tbh i dont understand Rib very well) and people who in Rib are called Ribstees some of them are nice some of them mug children (like bug bomb(they make fun of young Aoba for looking like a girl)) Then there is Morphine which is a gang who is working for the government. Rhyme also has gangs like Noiz’s team Ruff rabbits. Aoba’s childhood friend
