We're not really Doctors. (Shirou x Harem) Arknights x Fate

Chapter 24 - 2

Just because Shirou was bad at magecraft didn't mean that he couldn't work around his shortcomings. Rin made sure of that by teaching him the basics of magecraft after the Fuyuki Grail War. His time at the Clocktower also helped reinforce them to acceptable levels, if not push them to roundabout methods that allowed him to perform some of the more advanced craft.

Case in point: his ward on Sakura.

It was a simple ward that was tied to him. It didn't do anything aside from alert him if something happened to Sakura's health. A safety precaution. That's what it was meant to be. Though, it served a far more important role than just watching over her vitals.

The ward also kept track of Sakura's magic.

The moment her magic fluctuated and turned dark, Shirou fired on all cylinders.

"Nearl, I have to go." Shirou hissed when the Holy Grail suddenly spiked in power. It wasn't reacting to his intentions that was for sure. One of Shirou's rules for himself was never to use the Holy Grail's power unless the situation required it. If he used the legendary artifact at every turn, consequences would follow.

No, the Holy Grail was reacting to an outside presence. The spike in power was in tune with only one possible connection to it- the Minor Grail.

The Corrupted Minor Grail.

"Shirou-? What's going on?" Nearl saw Shirou freeze for a moment. The past thirty minutes had been spent driving away Reunion fighters from the escape route for the prisoners to escape.

"I'll leave the civilians to you." He wasn't going to bother hiding his magecraft now. Shirou was leaving Nearl to distract the Reunion with few reinforcements. Seeing her fight was enough to prove that the pegasus knight was more than talented.

The coming threat was beyond Shirou's ability. Even with the Holy Grail's power, he would only be able to match it at best.

Drawing on the Holy Grail's might, Shirou traced weapons from his armoury. Normally summoning them would eat a large chunk of energy, but the holy artifact was infinite in its supply.

"Trace On."

Nearly blinked as something began to glow between them.

"I am the bone of my sword."

They quickly formed into familiar shapes- a sword and a shield. Her eyes widened when she saw the sheer size of the shield. It was massive . The thing was easily as big as her body. The shield was dull grey with a cross-like motif with rounded edges. Two vertical sides of the cross were longer than their horizontal counterparts- the top tall enough to protect one's head over the shield while the bottom extended further down to cover the legs.

When it dropped in front of Nearl, the pegasi caught it deftly and found that the bottom was long enough to comfortably rest on the ground while she held it. It was comparable to the riot shields in size and felt every bit as heavy.

The sword finished forming at the same time as the shield. It was a medium broadsword that widened at the base. The pommel was blue, just like the base and the center near the top. Compared to the shield, the sword looked normal- if not for the strange sense of harmony Nearl felt once the sword completed. Just like the shield, it fell into her hands and the pegasi found her arts suddenly thrumming with power.

"Use these. I won't be able to stay for much longer." Shirou warned while pouring more strength into his legs. He can already feel the dark presence creeping over the Holy Grail. The artifact was warding off the corruption, but it wouldn't last forever. It was simply an artifact- not a sentient entity capable of directing thought and power.
