"Futile struggles!"

Saber wielded her holy sword with her right hand and rushed forward, trying to defeat the enemy before he could complete his incantation.

But Caster wasn’t foolish enough to pronounce incantations in front of a blade. He didn’t speak even one syllable of incantations, just chaotically let out the surge of prana that the Noble Phantasm produced.

Although the previous summoning magecraft was nullified, the pools of blood that stained the ground were still connected to the prana. The uncontrollable prana that spurt out flowed into that mesh of blood, but finally scattered apart without forming any shapes.

"Ku..."

Her sight was blocked off before she got close enough to strike; even Saber didn’t take a rash move and stopped her steps. Caster didn’t intend to complete the spell to begin with, but forcibly activated a magecraft that was bound to fail. That would be enough in this situation. The blood that didn’t form any summoned monsters immediately boiled and evaporated due to the saturated prana in them, spreading out in all direction as a fog. This is an imprudent skill that could only be used with the enormous amount of prana provided by a Noble Phantasm.

What he expected – was a blinding mist.

Even Caster, overloaded with confidence, deducted that it would be impossible to reverse the situation and arrive at victory at this state. The magus Servant quickly removed materialization in the time while the bloody mist covered Saber and Lancer’s sight. Faced with two of the three knight classes, he didn’t even get to leave a word behind. Swallowing his anger and humiliation, Caster rapidly left the battlefield in spiritual form.
