: This is the official introduction of Sanosuke, recognizable by the "Evil" (Aku) symbol on his back, representing his rejection of the corrupt Meiji government.
The story kicks off at the Akabeko restaurant, where Kenshin’s group encounters a band of "desperadoes for democracy". These ruffians cause a scene, eventually throwing a plate (or sake cup in the anime) that hits Kenshin. In a display of his peaceful nature, Kenshin refuses to dodge to avoid the object hitting Kaoru instead.
