This card is likely named after "Ataka-no-Seki (lit. Gateway of Ataka)", a gateway said to be established by the Togashi Clan. The gateway is famous as the scene of the Noh play "Ataka" and the kabuki play "Kanjinchō". The two plays depict a member of the Togashi clan (modeled after Togashi Yasuie, after whom "Stealth Rogue of Revelation, Yasuie" is named) being the defender of the gate. The flavor text of this card is a quote in the aforementioned Kabuki play.
