1 day = 3 months in the Spirit world and during Everloo mansion Natsu passed through the Spirit world which Lucy said that it is Impossible! Later in the Anime when Celestial Spirit King invited Lucy and others to Spirit world Virgo said that if you wear Celestial clothes you can enter into the Spirit world! How come Natsu was able to enter in the first incident? I could be the power of Dragon slayer or something ! So he could have stayed in the Spirit world for so long and thats why he is 80+
