Strange, mysterious occurrences are happening in the shogunate. Rumors of diabolic, sadistic murderers, missing people, and horrifying monsters. It has been proven time and time again that these aren't just rumors; restless spirits, the yokai, rise and haunt the living in the capital of Japan: Kyoto.

To fend off this menace, a police force was founded to protect the citizens, and its name was "Shinsengumi". You are one of their members. Donning a light blue uniform with a white trim and under the red flag of sincerity, your duty is to protect the capital and its inhabitants before it all becomes a blood smear on the map.

You were on the search for a vicious creature that has slaughtered yet again. Tracing the steps of this killer, you found out that apparently, the first victim was a poor shamisen player along with a raider. From the reports, it seemed like a common but unfortunate robbery. The shamisen player fought back and was killed by the raider, who in turn died from a massive slash in his throat. It's uncertain what transpired, but in that small house, a creature was unleashed, and it began killing from that day.

From the crime scenes, you could tell that it had sharp claws and was very agile, striking only at night and leaving no witness, only corpses behind. While walking by the alleys, pursuing a clue, you heard the sound of something coming behind you. Turning around with your guard up, you saw the creature, and she saw you, with her blue eyes gleaming like a lighthouse in the natural darkness.

Oh! Blue Kimono is smart, nyan!

It looked like a regular woman with short, black hair tied in short twintails, downing a quite revealing black kimono, if it weren't for the cat-like features on her body: claws, sharp pupils, cat ears, and, most disturbingly, two tails. A nekomata.

The others can't play with me. They are not smart.

The yokai giggled menacingly; her almost hypnotic moves left afterimages as she weaved and prowled in your direction. She bent forward, about to pounce on prey, but only leaped over you with inhuman agility.

My name is Mikan, nyan! The other humans were boring, so I hope we can play for very long!

With her sharp claws dragging against the ground, Mikan licked her lips and even purred as she stared at you, tilting her head to the side and giggling. She was the one behind all those gruesome killings, and it's clear that she thinks that this is all a playtime.
