Gon and Killua finally have a means of which to enter Greed Island, a game designed just for Hunters. Are their Nen abilities strong enough to help them survive in this new world? They must now train and grow stronger to uncover their secret abilities. With a helping hand from Bisque, they will be able to continue their quest to unravel the mystery behind Gin Freaks and this 'almost too real' hunter game.
In a massive online world, people act only as well as their conscience demands. When one player's punishment is to be trapped in this world, a disparate group of people seek the answers why. Their motives are varied; their methods even more so. What stands between when we tear down the walls of reality? Where does our soul end and we begin?
Like HXH, .hack//SIGN is another anime about a 'game' the characters log into. Although, you would want to watch the Hunter X Hunter TV series first to understand what's going on. But, the characters in both these anime must find a way to escape the game.
In this HxH OVA Gon and Killua are playing inside Greek Island. .hack//SIGN has a similar aspect where the protagonist character is forced to stay inside the game.
The year is 2022, and gamers have lined up on launch day for Sword Art Online, a hotly-anticipated MMORPG that lets players connect to an immersive virtual reality world with special helmets called Nerve Gear. Kirito is one such gamer who's eager to jump back into action, having spent a great deal of time as a beta tester, and quickly becomes friends with newbie warrior Klein. But soon, Sword Art Online's 10,000 players discover that not only are they unable to log out, the only way they can return to their physical bodies is by beating the 100-level tower's final boss - that is, if their HP doesn't drop to zero first, for death in the game means death in the real world. Now, with no one else to turn to, Kirito and the other participants must survive the game as best they can – some forming guilds, others ruthlessly leaving their peers behind, and many tragically falling by the wayside or to the merciless monsters populating the lands...
Both SAO and HXH greed island Ova are about a boy going inside a video where if you die in the game you die for real.
Both are about younger main characters with incredible fighting potential inside a VR MMO. The mechanics and rules of these worlds are often very different to the reality that the characters are used to and what you would expect when watching them.
Naruto Uzumaki is a young ninja who bears a great power hidden inside him, a power that has isolated him from the rest of his village. As such, his only dream is to become the Hokage - the most powerful ninja, and leader of the village; but first he needs to graduate! With his inability to perform even the most basic ninja techniques, it seems that all Naruto has going for him is his determination to succeed no matter what. Teamed up with the genius Sasuke, book-smart Sakura, and their team leader Kakashi, Naruto embarks on his quest to become the Hokage. But with outside forces posing a threat to the entire Hidden Leaf village, Naruto discovers that he must become much stronger if he ever wants to realize his dream and protect the friendships he's forged.
Again since the creators of HxH and Naruto are friends in life... their anime have some similarities. Gon and Naruto share similar traits... one of which is ignorance! You also get the same warm feeling from them and feel like you've known them awhile.
