Warning: Contains spoilers for Mashle: Magic and Muscles chapter 148.Mashle: Magic and Muscles has been one of Shonen Jump’s most exciting manga for years, and its latest chapter took that to another level for how it absolutely skewered Fullmetal Alchemist. Ever since its debut, Mashle has established itself as an irreverent parody series, with nearly every chapter doing something to make fun of the standard tropes of shonen manga. This style of writing also leads to parodies of specific stories, most notably with how the entire series, which revolves around a boy being enrolled in a school of wizards and fighting evil, makes Mashle a fusion of Harry Potter and One-Punch Man.
