In the lively town of Nerima, Hideki, the energetic one, and his serious brother Ichiro, along with their fashionable cousin Mako, manage a daikon radish farm. Aspiring musicians, they aim to fund their dream concert hall where their band, Nerima Daikon Brothers, could shine. Despite their efforts on the farm and Ichiro's side gig, money remains scarce. This prompts them to dive into quick-money schemes, often involving thwarting wrongdoers and seizing their loot. While their interventions halt the villains, the trio's pockets stay empty. Undeterred by setbacks or Officer Yukika Karakuri's interventions, they press on. Assisted by Nabeshin's quirky gadgets, the Nerima Daikon Brothers navigate bizarre escapades with their spirited performances and humor, persisting in their quest for fame.
