I Got Caught Up In a Hero Summons, but the Other World was at Peace Vol 7

From the Seven Seas Entertainment edition

WAR KING TROPHIES The sudden appearance of War King envoys Eta and Zeta has caught Koito off guard. They’re intent on bringing him before the War King, even if it means they have to drag him there. Just as things get dicey and Koito is sure he’s about to wind up as a missing persons, Sige and Anima appear to rescue him! When things go south for the War King’s envoys, more notable faces get involved--why has Noface, the Illusion King, shown themselves here?!
