I can say with full confidence, though, this is the work of Old Kinsei down in Tamamo. That guy's a genius, but whoever tampered with his work knows what they're doing, too...

You and the rest of the engineering guys can study this, but I'm not sure it'll tell us who tampered with Tamamo's bomb aside from "as good at onmyoudo as Old Kinsei" and that's...

[ His smile fades some. ]

Well that's a worrying prospect, I guess.
