Naruto's Guardian.

Arriving in a new world was not what I was expecting. Thankfully the Goddess who put me here. has allowed me to summon anything weapon, war, or civilian related from either real life or Video Games. Though I have one catch. Become the Guardian of a kid. Though I get to meet him for a week, when he's a child before joining him when he's 17. Oh. an I get a companion of my choosing.
