The newest tie in product for Yakuza of the End is Yakuza Energy Dragon. I’m pretty sure the main ingredient isn’t brains, so all the zombies out there may want to look to other products to get them through their busy days. For everyone else though, all you need is ¥798 ( about $10 US dollars) and this drink can be yours!

I wonder if this is still available? I’d love to try it.
