According to legend, in the late Heian period, Hyoe KUROTORU, one of Abe no Sadato's remaining retainers, went to Echigo Province and committed a number of atrocities, and even managed to defeat the Imperial army sent to subjugate him.
伝説によれば、平安時代の後期、安倍貞任の残党であった黒鳥兵衛は越後国へ入ると悪逆非道の限りを尽くし、朝廷の討伐軍をも打ち破った。
