Synopsis

Liese, the final member of the Trinity Seven, materialized within the Eternal Library bearing a seal of a demon lord, thus marking her as a potential ruler of the underworld. She sought to persuade Arata to align himself with the dark mages, promising aid in rescuing Hijiri. As Arata hesitated, she kissed him. In that moment of uncertainty, his magic was stolen. With a decisive turn, Liese resolved to attack the school.
