The poem, "There are few differences between rebelling and serving, only because I respect Emperor as my lord. With my ambition of 55 years fading away, I will return to my lord, of every thing" from 'Akechi Gunki' is an imitation of a farewell poem by Masanori OGURI, who committed suicide in "Echigo Sodo," which occurred in Edo Period.
「順逆二門に無し　大道心源に徹す　五十五年の夢　覚め来れば　一元に帰す」『明智軍記』江戸時代に起きた「越後騒動」で自害した小栗正矩の辞世の句を真似た偽作との説も。
