Gigguk, the anime YouTuber known for energetic explainers and comedy sketches about anime culture, helped popularise tournament arc talk among English-speaking fans who treat these competition storylines as a genre of their own. The term itself comes from shonen anime and manga, where heroes enter organised contests that test strength, strategy and rivalry. Clips like this circulate in edits and memes because they capture that shared excitement, letting creators frame any contest, from gaming brackets to anime debates, as if it were a high-stakes tournament.
