It throws you in the deep end and dares you to keep up. The first couple of episodes feel like someone spliced three different shows together, and the payoff for sticking around is that the whiplash turns out to be the point: a broke detective agency, a yakuza problem, and two identical twins living in the office, all pinballing between slapstick, action, and something that actually aches. Rentarou is running his dead father's business three weeks into the grief and pretending he has it handled, which is why Sara and Souju hovering constantly reads as more than a gag setup. The animation is doing real work here, elastic and show-offy in a way that earned the FLCL comparisons honestly rather than as a lazy shorthand. The logic of the plot will not survive close inspection, and fans who love this thing know that and do not care. What sticks is the chemistry, and a romance that lands harder than a series this silly has any right to.

Rentarou has stepped into his late father's shoes at the Futaba Detective Agency, a business he took over only weeks after his father died. His father was something of a legend among the colorful locals of the Nikotamagawa shopping district. Working alongside Sara and Souju, identical twin assistants who live under the same roof, he soon finds his routine thrown into chaos. Sara ends up destroying the office, which is also his home, while trying to escape the Chinese mafia. Meanwhile the neighborhood yakuza hold Rentarou hostage over a mishap between his cat and their boss's pet bird. The result is a comedy with dramatic and romantic threads, built around an unlikely detective and the twins who share his life.
