Plot: 3 weeks after Journey Across Universes and a week after Fairy Tail's Tartarus Arc, Naruto decides to take Natsu's offer in joining Fairy Tail, though only temporary. Meanwhile, Ivan Dreyar, bitter over his defeat during the Grand Magic Games, hires legendary mage hunter Grosvenor Tout for his sinister plans, which involves the capture of all the known Dragon Slayers! All Dragon Slayers are not safe from the eyes of a hunter! Can the inclusion of Naruto be enough to fight this unpredictable Hunter, who has never lost a prey, nor let any live?
Naruto Uzumaki: 3 weeks after saving the whole multiverse from the Jack of Blades, Naruto has temporarily joined Fairy Tail in order to cope with what happened during Journey Across Universes, and the fact that Moka said that he could have a harem like his cousin, Rito Yuuki. During his stay at Fairy Tail, Naruto also has to take care of his cousin's "daughter", Celine.
Natsu Dragneel: Main protagonist of Fairy Tail, One of the members of The Twelve, and one of the few people who've fought on equal grounds and defeated Naruto in pure combat, Natsu and Naruto respect each other as fighters. They also have a brother-like friendship.
Lucy Heartfilia: Natsu's girlfriend, Naruto has met Lucy before(details will be explained in the future), forming a friendship with her. During his 2 weeks with the guild, Naruto had sex with Virgo, Lucy's Celestial Spirit, many times, which caused Lucy to unleash her female fury upon him whenever she saw the two getting intimate together. He also slept with Aries.
Gray Fullbuster: Natsu's rival/friend, Gray has finally started dating Juvia. Gray finds Naruto's presence to be nice. During Naruto's stay, the two posed shirtless alongside Lyon for the front cover of Sorcerer Magazine, a feat Elfman found very manly. But in all seriousness, they respect each other as fighters.
Juvia Lockser: Juvia sees Naruto as an older brother she never had. When she wants help with her relationship with Gray, Naruto gives her some advice, mostly revolving around telling her to appear in Gray's room, wearing lingerie and screwing his brains out, or appearing in his shower naked and helping each other(Gray and Juvia) clean themselves, which works.
Gajeel Redfox: Though antagonistic at first, Gajeel instantly began to respect Naruto after Naruto and Gajeel had a verbal argument.
Laxus Dreyar: Laxus wants to fight Naruto after hearing about Naruto's power and his many battles, a fight Naruto doesn't want to do, since Naruto comically finds Laxus intimidating.
Makarov Dreyar: The Guild Master instantly likes Naruto due to him paying off all of Fairy Tail's damage for free. He also helps Naruto train in using some magic.
Happy the Cat: Naruto brought a lot of fish when he first came to Fairy Tail, earning his friendship. Happy will be seen babysitting Celine whenever Naruto can't, earning a fish every hour.
Celine: Naruto's "niece" and Rito's "daughter", Celine accompanies Naruto due to an Rito suggesting that he takes her with him since Naruto doesn't visit Rito a lot.
Chelsea: A mysterious assassin who works for the assassin's guild Night Raid, Chelsea has her eyes set on Naruto. Why? (Hint: She doesn't have romantic feelings for him, but it has something to do with MARVEL's Original Sin. It also has something to do with Naruto's parents)
Grosvenor Tout: A legendary and wanted mage hunter wielding a multi-purpose collapsible magic gun and a large array of mage hunting equipment, Grosvenor has set his sights on capturing all Dragon Slayer Mages for his employer. Killing Naruto is a bonus.
