Stories about revenge are the best when they are well done, and this dorama executed it perfectly. I love that all members that are involved in the revenge (the guilty part, the vengeful one) have surnames that start with a number. I think it was a wonderful detail, starting with the MC (Ichinose Koichi), then with the leader of the killings (Nishina) and his minions (Rokutanda, Nanao, etc). The story was sooo good. In every chapter, something is going on. Koichi getting closer to the family, in order to get the one who ordered Koichi's family to be killed. Getting his revenge on the minions who murdered his family, on the one who almost killed him, on the detective who pressured him when Koichi was just 9 years-old to lie that his father was the one who murdered the whole family. When it looks like the villains are almost catching up with him, Koichi has an ace up his sleeve. I love when the MC is wittier and quicker than the villain. He was perhaps a bit ruthless, but I couldn't help but empathize with him. Kusanagi was excellent as Koichi. You could feel the rage in him, and if it weren't for that tragic past, he would be a good guy. He was satisfied when he could have his revenge, but with those tears, you can only wonder if he was also a bit sad. Ichimura as the main villain was perfectly cast. He does wonder in this kind of role. And all his children were excellent as well. In conclusion, the Nishina family was perfect. That ending was O_O WOW. A whole 10/10 for me! Honestly I don't remember the music, that's why I rate it 9. I was just too engrossed with the story. I am not sure if this would be a re-watch for me, since you can't compare watching this kind of story for the first time with watching it for a second time. Nevertheless, if someone asked me to watch it with her/him, I'll gladly do it, since I can't recommend this dorama enough. ... I can't believe that this hasn't more viewers and reviewers. This deserves more recognition in MDL, highly recommended.
