Asano Naganori
The story tells the true story of Asano Naganori who attacked Lord Kira Kozenosuke with his sword in the Edo Castle after Kira had coaxed the young lord in the late 18th century. Even though the wound was only superficial, Asano was ordered to commit suicide. The 47 Asano Ronin (former retainers of Asano) led by Oishi Kuranosuke (Asano's chief adviser) came back to revenge their fallen lord against Lord Kira and were victorious but the Ronin were ordered to commit seppuku later by the Tokugawa Shogunate.
