User blog comment:Neko Neko no Mi Model: Russian Blue/The potential merits of a Time-Time fruit, particularly one held by an Admiral/@comment-24769684-20180529161253

My prediction has always been that Ryokugyu has the Sound fruit. But I don't know. The only thing about the fruit is that it has to match up to his color (green) and I don't know what fruit does aside from the plant fruit.
