Gon is a young child with a lot of strength and even more determination. He uses this determination to acquire a nearly impossible-to-get game. Once he and his friend Killua start playing however they are sucked into another world entirely. One where they must acquire cards and train their strengths to even greater heights. However, this deviation from the main plot of the story takes what was previously a shonen anime and edges it much closer to the isekai genre. There is still plenty of fighting, plenty of friendship, and plenty of puzzles for the boys to solve, but the introduction of an isekai element was a bold and wonderfully executed move.
