With the new user of Belvac attempting to spearhead the attack only to be frozen by Esdeath easily, her comrade, the User of the Danger Beasts then attempted to have his remaining Danger Beasts kill her in mass numbers,only for Esdeath to then easily freeze them to death. Their comrades the new users of Heavy Pressure, Spectator and Balzac then attempted more cunning and indirect attacks to kill her, only to be brushed aside by Esdeah as "annoying" and they were defeated. Later the new users of Adaysu, Die Leaguer, Shamshir, Extase and an unnamed Teigu then attempted a more direct approach and use combo attacks and teamwork to defeat the general, only to be again be defeated easily by Esdeath using her own raw skill and nearly killed by her if not for the intervention of Akame who then defeated Esdeath in a epic battle.
