A new website Slusho.jp was reported by TLC member Chucklez.
One of the code names for the 1-18-01 project is "Slusho". The site has a very similar feel to the Apollo Candy website from the Lost Experience ARG.
There is a "feedback" section where you can email the Slusho website, but as of this moment, it is just auto-replying with a form letter:
Slusho! loves your mails!! You Can't Drink Just Six!!!
Now...off to hack the flash files... :)
