[Nyororin]

I can tell you what`s written, but it really doesn`t have much of any meaning.

氏賀　Y太

I`m going to make a very wild guess here and say... Someone`s alias? 太 is generally at the end of a male name, and the way it`s written just feels like an alias. The first part can also be read in a way similar to a last name...

But that`s really just a wild guess. If that`s not it, it really doesn`t have any meaning.
