“From an early age, Ranmaru was an attendant to Oda Nobunaga. Recognized for his talent, loyalty, and unusual beauty, he was appointed to a responsible post. Ranmaru and his younger brothers perished defending Oda Nobunaga during the Honnō-ji Incident. Ranmaru’s bravery and devotion is remembered throughout history, and especially during the Edo period because of his decision to commit seppuku and follow Nobunaga in death.
Oda and Mori’s lord-vassal relationship followed the nanshoku tradition - an intimate relationship - and was widely admired in Japan for its strength. In nanshoku literature of the Edo period, it was widely understood that Oda and Mori had a sexual relationship that was commonly found in those times.”
