*** I washed my hair with soap today D: ***

Prologue

25th of July 1890, London, England.

It was a usual summer day. The sky was cloudless blue, the sun was shining so brightly and radiating heat that felt hotter than fire.

Or at least, it was what it felt like for a certain teal haired innkeeper.

"Ah, man… It's really hot." Miku wiped the sweat pouring down her forehead. She tightened the grip on her shopping bags a sea of crowd right in front of her; as much as the teal love shopping, a crowded market was never her best friend. Especially in a ridiculously hot summer where people's sweat ar- she should stop thinking about that, it made her feel disgusted.

"I thought you once said to me… You love summer…?"

Rin asked from behind her. She was also holding shopping bags, but Miku insisted that she held less despite Rin's intention to help her shopping.

"The only reason why I love summer is because it reminds me of… You know, the fireflies, the clear night sky, and the fact that my birthday is near. I never said I love the heat." Right… Miku's birthday was on August. Mikuo told her once. He said forgetting Miku's birthday would be one of many reasons that could make her kill him.

And so he fled before that could happen. Miku's getting older, and as there would be a time when saying 'Happy Birthday' to a girl means 'Ha! You're getting old!', he really didn't know what to do.

Or so he said. Rin wasn't sure if he was joking or not.

Remembering Mikuo who's already left made Rin remembered everyone else who also went away after Ted's execution. Meiko and Gakupo had returned to Japan. The samurai was obviously worried about his sister Gumi, but Rin wasn't sure why Meiko went along with him. Although Rin wasn't sure why Gakupo came with her either.

Sure Meiko came as a tourist, and Rin understood why she'd leave after all the stressful events, but... she had thought that Meiko would stay and help Len finish up the case.

If it could be called a case.

It all started as a favor. It's more of a personal investigation than a case. Len, the one-armed detective who was also Rin's employer, said he was just helping Kaito investigating an organization, when it turned out the said organization was apparently the cause of his every misfortune.

Let's just say the realization made his luck even worse.

And everything spiraled out of control.

In the end, what saved them was... Ted, the supposedly bad guy. He gave advices about the organization and took the blame for the burnings that Len (and one by Kaito) did. When Len, being a good detective he was, wanted to tied up loose ends by asking him more though, he found that someone had erased Ted's memories of the biggest mystery of all.

Who Rin was.

Someone gave a warning. He said Len had to stop looking. Obviously, it only made him even more curious. He then asked Kaito to look up some information about that man and the organization he was in, but the blue haired man just left.

He didn't say where and why he moved, or how to contact him, and Len was so mad about it. It's mainly because he hadn't done his job, thus cut out Len's ways to investigate the organization. The detective hated unsolved cases.

Rin's grip on the shopping bags tightened, and it was noticed by Miku. She let out a sigh. Rin had been gloomy since Kaito left. Even though Miku was glad that the troublemaker was gone, his absence really brought up new problems. Mainly to Rin's employer, but still Rin was obviously affected by it.

"By the way, let's stop at Luka's café for a bit. I need a cold drink now." Rin agreed and simply nodded at her.

Miku sighed once more.

If only the riddle could be solved...
