But as things are in JJBA and the Nasuverse, the unusual always gets drawn to itself one way or another. This time, it's obnoxious delays, a Kool-Aid cult armed with the power of negative thinking, a vengeful tulpa, and the very last vestiges of what remained of Araya Souren's plans that force the inevitable teamup between the mangaka and the services of Garan no Dou.
Rohan's the man for the job. Not only is Heaven's Door not as over-exploitable as some of the other Stands in Jojo's, it's balance of versatility and interesting application put it in line - and thus more meshes more easily - with the types of feats T-M supernatural powers are capable of. Combine this with how Rohan is decently famous and that means that everyone in GnD would have something to say about him (Touko I'm sure, being as eclectic as she is, could have some amusing dialogue with him) and that means there's potential for entertaining character interactions, along with a healthy serving of bonafide Nasu-Araki action/horror weirdness.
And yes, Shiki would eventually be able to see and kill Stands. Next loaded question, please.
