Koumyou nods to the first bit, and reaches up to touch one side of the Seiten around his shoulders after Genjo finishes, looking thoughtful. "The tethers looking for people who are similar is just my own theory, but... you know. Spiritual tethers."

Kind of a thing Sanzos have to deal with, isn't it? Just like how Koumyou can feel the Maten's location right now just as surely as his own thumb, after all that time as its lone protector. Keeping it safe. He'd always meant for Genjo to inherit the Maten from him even, if he hadn't meant for Genjo to inherit both so damn early.

Tenkai had said he'd know when the Maten was ready to be passed along again. He'd been right, as always.

(And he'd mostly only ever seen everyone's future deaths, hadn't he? Until Koumyou. Or including Koumyou, perhaps.)

...He realizes he'd lost himself in thought, and comes back with a slight shake of his head to clear it.

"Of course, but until recently our only source of data on anything about this situation was the train itself. Now we have the Void Ministry to deal with too, but since they don't remember the train's world ever having existed... it's hard. Plus, they're a governing body."

And thus never particularly trustworthy even in the best of times, which this is not.
