Who is Tenguyama Hitetsu waiting for?

In the previous chapter Hitetsu (The guy with the mask) said he was waiting for someone. I'm wondering if anyone has any theories as to who that might be. I'm thinking it could be allies or something. I think he is waiting for someone worthy enough to wield the "Nidai Kitetsu". If Nidai has been passed down for generations since Kotetsu, up until even Tengu's generation, it means that there's been no one worthy of wielding it till date, as what use is the Nidai in the hands of a blacksmith?

I'm sure Kotetsu didn't create a blade as fine as Nidai so it can be used as interior decoration. If he's waiting for someone capable of wielding the Nidai, then it is most definitely Zoro, seeing as he seems to be qualified to carry the heavy curse of that series of blades, with him already having Sandai in his possession. Less obvious answer is that he's waiting for a successor, someone qualified enough to inherit his skills.

The thing is, hitetsu is waiting for someone specifically in amakusa village. He could have gone to a better place but he is choosing to stay in amakusa village because whoever he is waiting for might not be able to find him if he moves. So, it's a lot like Otama waiting for Ace. It's someone who hitetsu has met before at amakusa village and if the person returns, he would try to find hitetsu at amakusa village so that's why hitetsu is staying there despite the village getting wasted.

If he is waiting for someone to break the curse or some chosen one plot line, then there is nothing stopping him from moving. The chosen one will find him wherever he goes.
