Tunnelbear VPN: https://chrome.google.com/webstore/d...bccaookpfjihpa
There seems to be a general rule of thumb about not using free VPNs when doing things that's aren't so legal (torrenting), but it's fine for just getting past DMM's region block.
It requires email + password, for free it provides 2000 MB per month. This means you have to disconnect from the VPN as soon as the game's page loads, otherwise you're wasting data on FKG assets (which can be quite big).
