You could hear the police sirens across the streets even though the rain was loud. The sky was already pitch black and only the lights of bars and streetlights made it possible to see. Only a few people were outside and walked rather fast. Except one mysterious man. He walked casually down the street and had no umbrella, which made his black hair turn wet. His black coat was already soaked.
This man was Kiku Honda, a detectiv who was famous for solving multiple crimes and murders along with his other members.
Only a few minutes ago he was called by the police to a bar, where a woman died. A witness said she just fell over and stopped breathing. This seemed a bit odd for Kiku. He asked some people if she had someone by her side, but the bar keeper said she was alone all the time. Kiku inspeced her drink for poison but there was none. The people in the bar also saw nothing suspicious... Nothing in the bar seemed conspicuous or gave him hints.
'How did she died?' asked Kiku himself. While he walked he thought about every detail, but he simply didn't know. He made some theories and possible ways how she died, but after a while he ended up in the hotel he lived. After going through the entrance he took the stairs to get into his apartment. After the door was opened he saw one of his partners sitting in an armchair and reading newspapers. Kiku laid down his coat and grabed the attention from the younger man.
"Oh, ibwa Kiku! Why are you so late?"
The name of the young man was Yong Soo. He was still too young to work for the police but helped the detectiv as much as he could. He also had a good observation and was really intelligent when it came to logical questions.
"Well, a woman died in a bar and there is no evidence how she died or whether was even killed. I've been thinking about it and was just... strolling around town.", said Kiku quiet.
"You just think too much. How about you relax a bit, you look tired", noticed Yong Soo.
Kiku nodded. He sat down and drank some tea with his friend. Even though he thinks that Yong Soo is too childish and too loud he likes him a lot. He himself is rather calm and hides his emotions, thinks a lot and is rather a loner. The only friends he got are Yong Soo and Yao Wang. Yao is the oldest of them all and like the 'leader'. Yao and Kiku always argue about how Yao should stop treating him like a little kid, since Yao just wants everyone under his control. Even though they get along pretty well and almost have the same skills. Those three are like a family.
"It's pretty late... I guess I go to sleep now", said Yong Soo and yawned.
Kiku nodded. He still sat on the couch, drinking his tea, thinking about the death of the woman. He got the information that she was from russia so why should anybody make the whole effort to kill her here and not in russia? How he knew somebody killed her? Well seemes a little bit odd when a healthy person dies without reason.
Kiku sits there and thinks. He looks at his watch. 1:03 am. He should go to sleep now. He sees Yong Soo in his bed, being curled up in a ball and snoring. On the other side of the room is Yaos bed, but he comes home rarely, that's why it's empty the most time. Kiku goes to his own bed and immediately falls asleep.
