Lina then proceeds to cast another [Fireball] and eliminates the bandit, though she is disappointed that her infamy doesn't account for her being a "Magical Genius", but takes solace that she did a good deed. Her companions, Amelia Wil Tesla Saillune and Zelgadiss Graywords state that killing bandits and stealing their loot shouldn't qualify as a good deed.

While she never heard of his name before, her experience with Fibrizo causes to act with caution.Before Momonga can explain their situation, Lina attacks him with a [Burst Rondo]. The attack fails as it is blocked by a Death Knight, so Lina casts [Raywing] to fly in the air with her companions and escape the room.
