Naruto 605 gives some light into why Kakashi had to kill Rin, we also discover that as Kakashi kills Rin, both Obito and him receive the Mangekyou Sharingan, Obito also discoverers a hint of his true power when he fights and notoriously defeats a large number of Mist Ninja’s.
Naruto 605 continues on as Rin spews blood out while Kakashi doesn’t regret what he did. Kakashi takes out his right arm from Rin’s chest and Rin falls down. Obito looks towards Kakashi and Rin as it seems as though he murdered Rin. Surrounding Kakashi and Rin are a large number of Mist Ninja’s. One of them says that Kakashi took Rin out, just when they finally managed to get their hands on it.
It seems that they wanted something from Rin, Kakashi had to kill her for this sake. At this point, Kakashi is really weak, Obito is seen to get really pissed as the spirals surrounding him start to come back to his body. Both Kakashi raise their faces as they obtain the notorious Mangekyou Sharingan.
As Obito gets even more pissed and angry, Kakashi has run out of chakra, he closes he’s eyes while he cries, he also falls to the ground with no hope. Obito shouts to the heaven in order to get the Mist Ninja’s attention, he does this so they don’t get their hands on Kakashi and Rin.
He develops tree spikes on the right of his body. The Mist ninja’s throw some Kunai , but unfortunately they just go straight through. At this point, the Mist Ninja’s attack Obito but found that Obito’s Mangekyou Sharingan has just enhanced his strength and speed. He hits the Mist and grows his tree inside the ninja which basically kills him directly.
After this he starts to kill countless number of ninja’s, one after the other, they all go down. Obito is attacked by three ninja’s, he jumps and spin kicks all of them. The list the ninja’s have to do is to retrieve the girl, even her corpse will be important. Obito hears this and quickly uses his technique to get passed everyone.
He throws a wood piece and does a hand sign which quickly grows the wood piece piercing through the body of the ninja.s Obito then punches and kicks the Ninja’s face. Obito smashes the face of the Ninja, then grabs his head and pierces through it.
At this point, Obito is completely covered with blood from the mist ninja’s. Obito then uses his Genjutsu or his Mokuton to grow trees spanning towards the moon, in small spaces, it traps all the ninja’s within them, it then squeezes which bursts out blood from each and every ones body in the tree. At this point, blood rains from the skies towards the ground. At this point, Obito looks at the corpse of Rin saying that he’s in Hell. Naruto 605 ends here.
What a fantastic and crazy chapter. Obito just went all out using his Mangekyou Sharingan and Mokuton! It’ll be an interesting story line after this, and why was Rin so special that Kakashi had to kill her? We’ll probably find out later on! Can’t wait for next week’s Naruto 606, it’s going to be truly epic!
