Souls are indeed one of my areas of expertise! [along with traps, poisons, diseases, parasites...] I am attempting to find common threads between the people and worlds brought together by 6350.

Ah, but now it's my turn... why might your reiatsu -- your Saint graph -- feel so similar to Holmes? Unfortunately, my sample size of Heroic Spirits is rather small... you, Holmes, and "Archer" Shirou Emiya. But I can assure you that Emiya's spiritual signature is not one I could confuse for anyone else -- not even his red-headed alternate self. I didn't mistake you for your rival because you look the same, you know.
