The joke structure in this show operates on three levels at once: the sarcasm lands, the historical absurdity lands harder, the character development sneaks in when you're not looking. Seikichi and his crew are trying to break a tyrannical system with fireworks and obstinacy, which means every episode is both genuinely funny and genuinely about something. The animation is strange enough that it stops being window dressing and becomes part of the comedy itself.
Seikichi runs a fireworks shop in Edo, where the ruling council has banned nearly everything fun, from celebrations to color itself. Life under their iron grip feels suffocating, yet Seikichi and his crew refuse to let their art die. Then a peculiar girl appears with an impossible dream: she wants a firework powerful enough to pierce the sky and reach the moon. What sounds like fantasy becomes Seikichi's obsession, and suddenly his quiet shop transforms into a hub of wild invention and rebellion. Building toward this impossible goal means outwitting authorities, gathering allies with their own buried passions, and discovering that some dreams are worth risking everything for. Comedy crashes headfirst into genuine heart as ordinary people chase something extraordinary. The tone balances laugh-out-loud moments with real stakes, mixing historical Edo atmosphere with the pure joy of creation and friendship. This is for anyone who loves stories about underdogs defying systems designed to crush them, where rocket science meets stubborn human determination.
