About
Kimizuka Kimihiko is a crisis-magnet. So it is no surprise when his rather mundane flight suddenly enters a state of emergency with a dire need of a detective onboard. Unfortunately, his attempt at avoiding trouble is foiled by a beautiful girl with silver hair who goes by the codename Siesta. Declaring herself a detective, she unceremoniously drags Kimizuka into the case as her assistant. That incident spelled the beginning of an adventure around the globe that went beyond his wildest imagination. Putting their lives on the line, the two took down criminal organizations, prevented disasters, and saved thousands. But the curtain closed to their epic journey with Siesta's untimely death three years later. Resolving to live an ordinary high school life this time, Kimizuka spends a year maintaining a low profile. However, as fate would have it, a girl with an uncanny resemblance to Siesta comes crashing into his life, threatening to throw his peaceful days into disarray.

Episodes
Season 1
Attention Passengers: Is There A Detective on Board? / Commence Adolescent Romantic Comedy
Kimizuka, a middle-school student, meets the beautiful detective Siesta in the process of thwarting a plane hijacking. As they next investigate a mystery at Kimizuka’s school Culture Festival, Siesta urges Kimizuka to become her sidekick.
I Still Remember, After All This Time
Kimizuka is approached by Nagisa Natsunagi, a girl with a yearning seemingly inspired by the heart she received in a transplant. When Kimizuka asks Fuubi for help, she takes them to meet an unexpected someone who provides surprising information.
That's Yui-nya Quality
A teen idol, Yui Saikawa, enlists Kimizuka and Natsunagi--who has taken up the mantle of legendary detective--to guard a priceless sapphire. In preparing for this, the two realize that more than just a precious jewel is at risk.
What I See in That Eye
On the night of Yui Saikawa’s big stadium show, Kimizuka and Natsunagi struggle to protect her from a hidden assailant. But the further the two dig into the plot against Saikawa, the clearer it becomes that the teen idol has secrets of her own.
That Was Directed at One Year in the Future
Siesta and Kimizuka investigate a series of murders by someone called Cerberus, who for some sinister reason steals victims’ hearts. As Cerberus eludes Siesta’s pursuit, she comes up with a more desperate tactic, much to Kimizuka’s dismay.
Crimson Devil, Ice Queen
Siesta takes an extreme risk to stop Hel and her mutated terror-beast, and pays a price for her courage. The outcome halts the fight against SPES, at least temporarily. In the wake of this battle, Kimizuka makes a surprising discovery in an alley.
In Time, You Will Recall this Day
While Siesta convalesces, Alicia takes on the role of substitute detective and seeks the Eye of Sapphire, with Kimizuka’s assistance. When at last Siesta recovers, recovered, the three celebrate, but this celebration takes an unexpected turn.
With That, We Set out on a Journey Once Again
Siesta has recovered and is eager to press forward with pursuing the serial killer and SPES. Alicia, however, insists on being involved, and as the two clash and sparks fly, the mystery of Alicia's identity comes more sharply into focus.
