Saber sensed the enemy’s intentions after she defeated three monsters.

She didn’t yet know the reason. However, the overly fragile tentacle monsters and Caster’s unnatural degree of confidence triggered Saber’s instinctive alarm.

After defeating ten, Saber finally confirmed the reason for her unsettledness.

The amount of enemies didn’t decrease. No matter how many she defeats, new enemies would emerge. Caster’s summoning magecraft continuously called for reinforcements from other worlds.

Even so, it didn’t matter; Saber silently steeled herself. No matter how big the number of enemies may swell into, all she has to do is to defeat them twice as fast here. Driven by her boiling morale, Saber’s sword sped up in the blink of an eye.
