Sakura and Shirou
Shirou watched with a look of shock on his face as the alternate Sakura simply absorbed the force of the blast into her shadow, with absolutely no apparent effect. Sakura was a little less surprised, aware that it was in principle possible, but nevertheless she was impressed by the girl's power.
"Apparently I did, yes. But I'd far sooner do that than overestimate you", Shirou said, in response to the girl's statement.
They were even more shocked at the girl's speed of movement. Fortunately, though, Sakura was used to fighting against such powerful enemies, and she repeated her trick from earlier.
"Abfangen! Entmündigen sie!" Sakura shouted, sending her hornets after the girl, instructing them to attempt to incapacitate her with their tranquilizing stings.
The hornets did as instructed, splitting into smaller groups in order to be more difficult to destroy. Wasting no time, Sakura began to chant again.
"Aufsaugen! Aufsaugen! Aufsaugen! Verschwinden! Teleportieren!" she chanted, sucking Shirou into her shadow dimension once more, before disappearing and reappearing on top of another derelict building.
Realising the girl's power, Sakura additionally sent small familiars to every other potential vantage point, ensuring that she would have the ability to continue to escape her much-faster opponent in this manner. Then, having recognised the girl's power and escaped to a safe distance, they made a second attempt at attacking her, this time taking her full power into account.
"Erstelle Schattenball!" Sakura shouted, pointing in the girl's direction. "Anderer! Und anderer! Alles aufspießen!"
In response to Sakura's chanting, several more blobs appeared, just behind and to the side of the girl, as well as one above her. Then, on her command, they sprouted large spikes, intending to pierce her. Meanwhile, Shirou, taking advantage of the distraction Sakura was hopefully creating, began to chant once more.
"I am the bone of my sword!" he said. "Caladborg!"
With that, he fired the powerful Noble Phantasm directly at their opponent, not holding back in the slightest. Sakura, meanwhile, continued to summon up little blobs of shadow, each one designed to impale her if she was not careful. And, unless they were destroyed by either the explosion or the alternate Sakura's attacks, the hornets would continue to attempt to sting her.
