Hell

Hell (地獄, Jigoku) is chapter 605 of the Naruto manga.

Summary
As Kakashi releases Rin from his grip, both he and Obito, who is watching from a distance, watch her die; causing both of their Sharingan to mature and awaken their Mangekyō Sharingan. As Kakashi passes out, Obito flies into a fit of rage and arouses the attention of the Kirigakure ninja. Wooden spikes begin to grow from Obito's shoulders as he commences his attack, slipping through the barrage of shuriken thrown at him and going on the attack. Obito begins slaughtering the Kirigakure ninja with a Wood Release technique, which Spiral Zetsu calls the Wood Release: Piercing Branch Technique, applauding the boy for its use while stating that it now knew why Madara had chosen him. Obito cries out in anger once more, killing an even large amount of ninja with his wood. Shortly after, standing amidst the carnage he had created, Obito declares that he is in hell.
