If not, then its bullshit. Grimoire Heart was only strong cause of Hades, the 7 kin, Bluenote and possibly Kawazu and Yomazu. I'm pretty sure that the current members of Tartarus are far stronger than the lame cannon-fodder that made up most of the Enemy Guilds in the series if they can survive Kyouka's spell.
