Sakura and Shirou
Sakura and Shirou frowned at the boy's comment. As he was responding to Nanako, however, he suddenly froze, weird black, slimy creatures gathering around them.
"Everyone, get back!" Sakura shouted.
Immediately, she summoned up several human-sized shadow familiar, which immediately moved to engage the weird slime creatures, focussing on attempting to delay them, but also trying to destroy them if possible.
"Nanako, get the kid somewhere safe and protect him!" she added, reinforcing her legs and taking a giant leap backwards, before summoning up her shadow bow, beginning to charge a shadow arrow.
Shirou, meanwhile, summoned up his two trusty swords and leapt in front of the two bodyguards, preparing to protect them and Sakura from any sudden attack. As soon as they moved backwards, he would follow them.
"Let us handle this", he said to the bodyguards. "I'll protect you whilst you retreat."
