Idea #5

-The fox who speaks in hands-

Naruto/Undertale

This story begins when Naruto is six.

When Naruto is protecting Hinata from bullies he'll suddenly be sucked into his mind. He'll meet W.D. Gaster and his parents. Gaster will explain how human souls and monster souls work. Minato and Kushina will explain the Kyuubi to him. Gaster will demonstrate and teach Naruto how to use his abilities to fuse their souls. He'll then explain Naruto's soul. Naruto's soul will be Orange(Bravery) while also explaining Minato's Yellow Soul(Justice) and Kushina's Red Soul(Determination). When it is all over and Minato and Kushina are about to fade, they offer to fuse their souls with Naruto's. Naruto's soul will be orange, red, and yellow with Gaster's white monster soul(an upside-down heart) in the middle keeping it together.

Naruto will be able to see souls. Naruto will find Kyuubi's soul. Kyuubi's soul will be mostly black with a small bit of blue at the bottom of his soul. When Naruto comes back to the real world he'll conjure a defensive structure made of bones around him and Hinata. When he looks back at Hinata, he sees that she has a soul that is half green half purple. After this incident, Hinata would start to follow Naruto around until he calls her out to join him. He tells her what her soul looks like and what it means. He helps her learn how to tap into her soul. Her green soul allows her to heal people's injuries and erect barriers to shield people. Her purple soul allows her to use purple strings to bind and throw people, etc. Naruto will learn to speak in Wingdings and will teach Hinata, Sakura, and Sasuke at first. Later the others will learn it too.
