While on a hunt, an amateur and unlicensed Wrecker, Shinji, encounters Crash: the world’s first sentient mecha. In Crash’s code lies the cure to the Rot – a nanomachine plague that’s slowly killing humanity, including Shinji’s only remaining – his sister, Omi.
Together they set off to heal the planet, being pursued by only every Wrecker, yakuza ganga, android assassin, influencer, and scumbag in Neo Tokyo.
