The severe illness represents the side effect of Shard ingesting those "filthy things," but since the side effects are manifesting, it also means that the power originally not belonging to Shard is successfully becoming a part of him.
Not only can he himself feel within his coma that the upper limit of his spirit and recovery speed are increasing, but the girls who take care of him can also feel it.
"His hair and beard grow so fast."
The 22nd day of the Month of Rising Wind, Saturday.
When Shard awoke to a brand-new morning, he heard Luviya and Tifa speaking.
He hadn't opened his eyes yet, unexpectedly discovering that he felt exceptionally good today. Although his body still felt somewhat fatigued, and the headache hadn't entirely disappeared, compared to the pain that felt like a sledgehammer pounding his temples in recent days, the current sensation was almost like Mia scratching his skin.
From his understanding of his body state, this could almost be considered healing.
