The Day the World Turned Upside Down for Me

Right now Hikaru is in great trouble, His mother killer is standing in front of his dad's corpse taking his step towards him to erase every evidence, with his every steps Hikaru rate of survival is decreasing drastically, but how did end up in that position to know that we need to backtrack to very starting years of Hikaru life's ,

All that started 10 year ago, when Hikaru was only 7 years old.

He was born in a family of cops, both of his parents work in tokyo police department. Due to their jobs they can't really spend time with their child but if we asks the 7-years old Hikaru the situation can't be any better. Hikaru is in crazy love with knowledge, from a very young age he want to uncover every secrets of universe and for that he has spent all the time to gather knowledge. Its not like he doesn't have emotion but he doesn't seems to care about them.

But when his father, Arakawa Tekasi  arrived that day something was differnet , he seems like a dead person walking he apparently even Hikaru seems to notice , then his father come to him and hugged him, which annoyed him but what was he gonna tell him nobody have prepared him for this , Tekasi tells him that-"Hikaruu Youurr ... your MOM is DEAD".

Hikaru's Mom was killed by a criminal who shot her trying to escape her after robbing the shop. This incident affected his father so much that he left the police department , while Hikaru was hurt but he continued his live after few weeks of her death.

Fast forward to 10 years when he was already become a renowned name in the country even being a teenager at that time , he was already been selected in a very esteemed high-intelligence training program developed by the country to gather god- gifted kid and nurture them to become greatest minds of future .

 Where is dad who left the police department has been working unlawfully to catch his wife murder, for past 10-year he is finding evidence for that cause. Hikaru and his father who are completely different from each other has grown very apart due to Hikaru's ignorance towards his mom's death.

And then we come to today when Hikaru was coming back to tokyo after he spent months in Nasa summer research program , after he landed in tokyo and get back to his apartment he founds some waiting for him. He was no one other than the person who killed his mother.

And without a word the killer lunged on him with a knife , Hikaru, confused, asked him-"who.. WHO are You" and the killer in next instinct stabs him in his abdominal and says-"I aM the SAme guy, WHo killed your BITCHass MOM HEhe... ehheehehehe".
