It'll probably be more of a spinoff since Penguindrum had a pretty definitive end with the Takakura siblings. I'm surprised this project (assuming it's an anime) even got greenlit, but I'm always happy to know that Ikuhara's up to something.
As I said earlier today to someone who shows me this link,there is a mistake:
You see, the name of the website also appear on the top (the tab) and there, it's spelled: PENGIUNBEAR Project. Would the staff really be that careless (yes, I know they are japanese)? So, I suspect it's a fake.
BUT if it's ever real, of course I would be happy about it! I can't wait for more Ikuhara's trolls.
I do wonder what it would be about though. The penguin symbol on the website is totally different from our regular penguins, so i'm guessing it's a new story, or a spin-off of one of the minor characters.
