Seaman all right, and we're just as desperately curious to find out why it exists as you are. The weird thing was tweeted by Seaman creator Yoot Saito, who also said that it was time to begin thinking about the end of the year, according to Andriasang's translation.
We have so many questions. Is Saito hinting at some kind of holiday announcement, or even better, some kind of holiday release? Do kids these days even remember Seaman? Is this related to that Nikkei report? Was this whole post just an excuse to publish that picture of Santa Seaman?
Answers, in order: We hope, probably not, maybe, and definitely.
