Mogai is fan slang for an adaptation that changes its source novel or game so heavily that it feels like a different story. Mo means demon and gai means to alter, so the word carries a sense of mutilation, and it is almost always a complaint. Typical targets are changed character relationships, a new ending, or subplots added to stretch the length. Viewers applied it to A Splendid Match and The First Frost.
