Shirou's body was surrounded by a vast current of magical energy.
His body had now become nothing more than a path for the magical energy from the Dragon's Magic Core to pass through.
The magical energy transformed through breathing reached the Magic Circle via his palms, then flowed into Sajyou Manaka's body.
Although she would probably never open her eyes again, Sajyou Manaka's life had at least been saved.
For that, he had to thank Kaijiri Shishigami.
As soon as Shirou and the others returned to the ground, Shishigami provided the serum for the Hydra Poison.
If they had been even slightly later, Aika would probably have been beyond saving.
As for why Shishigami had a serum for a divine-era serpent...
When accepting the Master's commission, the necromancer had stolen some formalin containing a Hydra hatchling from the Association, taking it as one of the advance rewards for participating in the war.
Then, after learning that the "Black" Archer was Chiron and the "Red" Assassin was Semiramis, he had probably anticipated that something like this would happen and prepared the serum in advance.
As a result, the serum had saved both Mordred's life and Aika's.
However, Aika did not possess a body as tough as Mordred's—the kind that could take a Holy Lance at point-blank range and still remain standing.
