I'm not sure what exactly this dude's name translates to, so he could either be a reference to Cerberus, the three headed dog that guards the underworld, or he could just be an overly ambitious werewolf. Either way, you don't chain someone's hands together for no reason, so he's probably not someone you'd want to meet while taking the trash out late at night.
Kenth Toy Works has customized a run of these figures from GEEK! and is offering them up now through this Wednesday at 23:00 Japan time. Here's how you can get your hands on one of them:
Please enter your Name, Address, Phone No and Email to [firstname.lastname@example.org]
All payments will be made through Paypal and if they generate more interest than the amount of figures they have then they will resort to a lottery system.
