- abel was the heir of his parents company, so he usually get in danger. one day, when they`re in their teenage, abel and dirga get kidnapped ther. dirga want to protect abel, it works but he can`t protect himself. abel get snapped when he knew dirga wasn`t breathing anymore. he killed everyone there then use their phone to call the police. dirga last word to abel is "its okay, don`t cry.. i always want to protect you, im sorry i can`t married overseas with you although it sounds cool, but remember wherever you go, ill always be with you". abel took the word seriously, he take some of dirga` bones and made a Katana from it (made by kiku, since him and dirga are close friends, he volunteered). since that day, that katana always on abel`s side, no one can touch the katana. the blade is so thin and sharp, it can slice 1ply tissue just by touching. but for abel, it becomes dull, the katana can`t hurt abel, it won`t. abel make a good use of it, he killed the traitor of his company, or anyone that want to harm his family. apparently, killing people that want to harm abel`s company/family is like giving food to the sword. abel know this, and he won`t let his sweetheart starve.
