Naruto's Beginning: Psychic Groudon

Accidentally reborn into the Sengoku era of Naruto. Emmm, where is the golden finger you talked about? What about the benefits for time travellers? Everyone else starts with kaleidoscope, samsara eye and so on, but you just give me a psychic contract? Wait, I seem to have contracted a Groudon! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
