What If Naruto Signed the Wolf Sage Contract Instead of Toads?

When a hidden second contract falls out of the Forbidden Scroll, Naruto Uzumaki doesn't summon a giant toad — he bonds with Silverfang, ancient alpha of a wolf clan sealed away generations ago. Trading solo ninjutsu for pack-based Fang Style taijutsu, sharpened senses, and coordinated shadow-clone tactics, Naruto's entire path through the Chunin Exams and beyond is rewritten one howl at a time. But an old rift between the Wolf and Toad clans is stirring — and Naruto isn't the only one who's noticed his chakra now reeks of a contract older than the toads.
