@ohgodwhy: Lol, you would probably end up in a gun fight with somebody else by the end of the day.
@UltimateHero0406: It'd be ok though because Sagara's got my back lol.
I would throw a party and invite all of Bleach, Fairy Tail, Naruto, Inuyasha, and Rurouni Kenshin. They all seem like awesome people to be around...too much?
OK, If I had to spend a day with just one, it would be...Naruto. In the very beginning, when he was all alone, the only thing that came to mind when I saw him was "I would have been there for him...I would have been his friend". I still think that. He turned out to be a good person. We would have probably chowed down different variety's of ramen :)
I would want to hang out with Goku. If I could add 2 more it would be Erza Scarlet and Ash Ketchum.
I would train to be a Super Saiyan/Mage/Pokemon Trainer.
I would ask Goku to teach me everything he knows, or atleast Instant Transmission and the Kamehameha, I would ask Erza if she would ever date Natsu, and I would ask Ash when the hell is he going to win a league besides the Orange League.
