help me download from u-next

[kienkzz]

hello, i want to be helped this:
can you help me to download this video? That service is coming from Japan, and you need to use VPN for watch + get license.
I'm banned in GetWVKeys.cc so I can't access that web to get key.
also can I ask: How to decrypt DRM in that website? and what step I need to do? I want to ask it because I'll do it for many video in that services.
Can you help me? Thanks for reading and replying.
Note: This video is free.
