I'm not good with creating stories so I post ideas (Naruto edition)

When Jiraya throw Naruto into an endless chasm with the hope of making him use kyuubi chakra, but sadly it didn't work (he was stuborn, hit into a rook and lost consciousness or kyuubi told him f$#k you) and Naruto fall into the bottom, more specifically into lifestream with mutated him giving him one wing (it don't need to be angel wing), ability to use mako, repairing his malnourishment (and I don't mean transforming him into Sephiroth giving him long silver hair and his personality) and as all living things are going to lifestream after dead (from what i know) he was able to meet uzumaki clan members and learn some things from them.
