Manga de Wakaru Soutaisei Riron

Everything's gone screwy at Tagai Academy. When the headmaster forces Minagi's entire class to study Einstein’s theory of relativity over summer school, Minagi volunteers to go in their place. There’s just one problem: He's never even heard of relativity before! Luckily, Minagi has the plucky Miss Uraga to teach him.
