Search Worlds Without End

When the story begins without its hero

Kimihiko Kimizuka has always been a magnet for trouble and intrigue. For as long as he can remember, he's been stumbling across murder scenes or receiving mysterious attache cases to transport. When he met Siesta, a brilliant detective fighting a secret war against an organization of pseudohumans, he couldn't resist the call to become her assistant and join her on an epic journey across the world... Until a year ago, that is. Now he's returned to a life that is normal and tepid by comparison, knowing the adventure must be over. After all, the detective is already dead.

WHO WERE YOU TO HER? WHO WAS SHE TO YOU?

While on an outing one day, Kimihiko Kimizuka and his three friends are kidnapped by... Siesta herself?! But they soon learn there's more to the story as she reveals the long-forgotten truth about Siesta's death. Will this be the clue that finally unlocks the secrets of Kimihiko's past?

What's wrong with this story?

After being kidnapped, Kimizuka, Natsunagi, Saikawa, and Charlie have learned the truth about Siesta's death... or have they? A girl who looks just like the deceased appears and informs them that the footage they've been investigating contains an error. As they hunt for an answer to a mystery that even Siesta couldn't uncover, the group will learn what it truly means to inherit the legacy of an ace detective. Though the detective may already be dead and the truth of her passing revealed, it's still too early for the epilogue...

Once the assistant to a great detective, Kimihiko Kimizuka took on a challenge Siesta bequeathed to him after her death and arrived at a conclusion that surpassed his wildest expectations. To bring back the great detective--the stuff of miracles--Kimihiko and Natsunagi fly to London yet again to obtain evidence that can bring down Seed. On the flight there, however, he hears the same words as he did four years ago: "Is there a detective on the plane?"

We won't let you die again!

Reunited with Siesta, Kimihiko is pulled back into action as assistant to the Ace Detective. Together, the two face off against Seed again and, with a little extra help, defeat him. Although that particular crisis may be over, the journey to awaken Natsunagi continues. In search of clues for how to save her, Siesta and Kimihiko travel to New York City. However, instead of answers, they find trouble brewing with the Phantom Thief-and worst of all, Siesta disappears!

Siesta and Kimihiko's first meeting did not take place during that fateful plane hijacking but rather four years earlier, when the Federation Government tasked Siesta with locating a spy in Japan. During her undercover investigation, she happened upon her future assistant, who had a connection with the spy she was looking for. With Kimihiko as her only lead, she enlisted his help in the search. But Siesta hid her identity with constant disguises, so unbeknownst to Kimihiko, he had already met the Ace Detective. Finally, the story of their true encounter--and the reason behind Siesta's invitation to Kimihiko on that day in the sky--is revealed in this prequel!

The second act is about to begin. The adventure of the detective and her assistant began ten thousand meters above the earth. They helped clients, solved cases, fought powerful enemies, and traveled all over the world--and then the detective died. The story should have ended there. But a year later, one girl's passion set it in motion again. After many battles and sacrifices, a miracle was granted. Now that it's all over, Kimihiko Kimizuka is basking in the ordinary life that comes afterward. (Am I okay with that, you ask? Sure. It's not like I'm causing trouble for anybody. I mean, it's true, isn't it? The detective is already--)

"Let's go on a journey to unlock the world's secrets."

Kimihiko Kimizuka was once the assistant to two Ace Detectives, and after achieving a miracle, the sequel to the story was ordinary life. The Ritual of Sacred Return was supposed to be the moment world peace was achieved--but instead, it was discovered that something was wrong with the memories of the world. As the search for the truth begins, it seems Kimihiko's memories of his brief but extraordinary adventure with another Tuner, Rill, may hold the key...
