Well this was a below average manga, with an interesting story but awful development and more to it, the greatest disappointment was that it was axed midway, it might have been a good manga but it was cut short and the story left unfinished, if it weren't have been axed it would be worth around 85-90 chapters. Not recommending to watch it, only reason is that you will not enjoy it at all when the manga stopped midway and unfinished.

Story:
(Spoilers - but well you can just read review and pass the manga)
The main character has a very less existence in real life andf being often teased as "Ghost boy". He later encountered a lady while he was running away after he threw tabasco sauce on a child's face. The lady then takes him to an office and introduces him to a tournament in which he would win a billion dollars.


There were 8 rounds in which a competitor should kill his opponent indirectly i.e. without hurting or directly killing him else it results into death. Moreover if competitor tells about tournament to third party, violation of rules resultant death.

In round 1, MC encounters a serial killer who had already killed three girls in past. He takes all information of MC, kills two more girls in subsequent way by arrows from crossbow and traps MC and makes him traumaterialised, then he tries to kill MC's sister, MC had became serious by noiw and made some moves, but all was going according to the opponent's plan. Opp. traps MC to police by trying to kill his own sister and gets him arrested. Soom at the end of 11th day he is realeased and got to know about his sister's condition and what the opp. tried to do with her. He then sets a trap for opp. where a detective kills opp. but the MC was trapped as his sister was there. In the end of scene a professor kills the opp. whom the opp. cared but shot her just before the detective comes, the detective shoots opp. and prof. and opp. falls off a building.
The MC wins and tells everything to the detective who indeed worked for the tournament's organizers and inserted an injection to kill MC, but instead MC was set on a repecharge round and there it goes shittier.

At the end of the manga, it shows that the opponent of tournament's second round is and story is shut!!!!
