A Poltergeist for a Sidekick
Uchiha Obito wasn't one to take life for granted. Just see for yourself at how many times he's weaseled out of the Shinigami's hands right at the last minute—too many times. But after managing to land a killing blow on his former sensei's son, then getting... decapitated (if you'd call it that, he grimaced) by none other than the hysterical father himself, he truly believed that it was the end for him. After all, the Rasengan that blasted through his neck and head killed him off before he even had an opportunity to break the seal he was frozen in.
I must be in Hell, then. Heaven couldn't be this dark, and with all I've done in my life, I find it far-fetched if I were to be in Heaven, Obito thought, either way, I would end up somewhere, right? Those thoughts didn't reassure him in the slightest when he saw nothing but himself in the dark gloom. As seconds turned into minutes, he soon found himself in a state of restlessness, a mood he hadn't felt in ages since he let loose of the Kyuubi in the middle of Konoha and battled his sensei with a fair chance of dying. None of this had gone according to plan and it all started with sensei's brat, he gritted his teeth, his agitation soon forgotten in the midst of deep-seated anger that swallowed him whole.
