Gacha games, known for their randomized reward systems, create an addictive environment that encourages players to collect characters, often leading to viral trends like the "Danganropa disease." This phenomenon illustrates how community participation and shared enjoyment can spread rapidly, much like a playful social contagion. Within the GL2 and Danganropa fandoms, players frequently share funny memes, tips, and fan art revolving around this “disease,” strengthening community bonds.

Understanding this phenomenon sheds light on the broader impact of social media-driven game cultures, where content creators and enthusiasts collaboratively create layered experiences that extend beyond gameplay.
