Mattaku Saikin no Tantei to Kitara

Once hailed as a genius high school detective, Nagumo Keiichirou now faces a very different reality. At 35, he's an out-of-touch, old-fashioned man with bad hips, running a failing detective agency on the brink of collapse. The fire of his youth seems like a distant memory.

His stagnant world is turned upside down when a sharp-witted high school girl walks into his office, not with a case, but with a proposition: she wants to work with him. This anime explores their unlikely partnership, asking whether this brash new energy can reignite Nagumo's dormant brilliance and adapt his classic methods to a modern world.

It's a humorous and heartfelt story about rekindling passion, bridging generational gaps, and finding unexpected allies in the most desperate of times.
