(The series already concluded last month, September 18, but I only started watching all the episodes yesterday. Hence, I decided to just make a summary of the final episode even though it’s too late already. ^^)
Apart from all the physical torture that Kaneki has endured from “Jason”, he also suffers from mental torment from Rize. She asks him about his mother, and Kaneki recollects the time he spent with his mom until she passed away due to overwork. He strongly believes that “it’s better to be hurt than to hurt others“, just like what his mother taught him. Meanwhile, Kaneki continues to count backwards by sevens from one thousand as ordered by Yamori to keep himself sane amidst the excruciating agony he experiences.
His fingers and toes are repeatedly extracted using a pair of pincers, due to his extraordinary regenerative powers. Jason also inserts a red-headed centipede in Kaneki’s ear, as he begs him to just finish him off immediately. Instead, Jason presents him with an unbearable task, and that is to choose who he is going to kill between Shu and Haru. However, since Kaneki cannot choose between the two who helped him earlier, Jason decides to kill both of them. Because of that, Kaneki blames himself for not being able to do anything. Rize continues to mock and daunt him for his inability to change himself and his beliefs.
She proceeds to remind him about his mother, and Kaneki soon falls into her trap. He finally gives in to his ghoulish psyche, and as his world drowns in red and his hair turns white, he devours Rize and finally embraces and acknowledges himself as a GHOUL.
Back in the chamber, Jason, who is still clueless about the changes in his prey, tells Kaneki that their time is about to end since the doves are closing in on the place. As Jason releases his kagune to devour him, Kaneki quickly unchains himself and bites the Aogiri member instead. During the course of their battle, Kaneki launches his Rinkaku kagune which eventually knocks Jason off even with his incomplete kakuja. He remains conscious though, as Kaneki questions him about numbers. He repeatedly strikes him as Jason begins counting backwards by sevens. Sitting on top of the tearful ghoul, Kaneki cracks his finger, a trait he inherited from his torturer, as he opens his mouth to devour him.
(Like what most fans probably felt, I was also kinda disappointed with the ending. It was a total cliffhanger, and because I was eager to know what’s gonna happen next, I decided to start reading the manga from the very start. I want to develop a much more established connection with the characters, especially with Kaneki. On the other hand, I must also give my compliments to the animation team. The fight scenes put me at the edge of my seat, and the amount of blood and brutality left me cringing. (But at the same time, there was this part of me that still wanted to continue watching them.) Though there were some changes in the story, the team still did a great job compressing some of the important parts in just 12 episodes. (Although the new characters were not properly introduced and the sequence of events were not put in the correct order like in the manga.) Anyway,the story has just begun, so I’m pretty sure that there will be a second season to describe the continuation of the events following the transformation of the main protagonist. And I’m gonna wait for it! ^^)
