A Certain Magical Index, part of the expansive Toaru universe, has inspired countless memes focusing on the collision between high-tech science and ancient magic. The most enduring trope is protagonist Touma Kamijo’s catchphrase, 'Such Misfortune!' (Fukou da!), which he exclaims whenever his luck-negating Imagine Breaker ability leads to comedic or disastrous results. Other popular meme formats include Index's voracious appetite and penchant for biting Touma's head, alongside the complex power-scaling debates involving Level 5 espers. These memes allow fans to celebrate the series' unique blend of intense supernatural action and lighthearted character dynamics.
