Why is it drawing attention now?
When normal words fail to describe the depth of a fan's adoration (Oshikatsu), fans compile chaotic essays. Often written during late-night hours of hyper-fixation, these paragraphs are jokingly shared as "Kaibunsho." In gaming communities, these passionate rants about character lores or fictional scenarios frequently go viral as copypasta (standard internet text memes). Fans often post them with self-deprecating remarks like "I wrote another kaibunsho at 3 AM," earning laughter and validation from peers.

Person B: "I read the whole thing! Your intense devotion shines through so clearly. That's a masterpiece of a kaibunsho!"
