According to viewers on platforms like Reddit and YouTube , this episode was a "return to form" for the series.

The dialogue between Margaret and the "mysterious voice" (Ludociel) and her desperation to save Gilthunder provided much-needed emotional depth.

Other members of the Goddess Clan, like Tarmiel and Sariel, also find human vessels, setting the stage for the upcoming Holy War against the Demon Clan.
