For more information that I can find
This is MimiProduction (or Mimi Neko)'s facebook page which I found it from his other video and he said "Hope you can help me share it out" in this SAS J-core remix post, so I assume this remix is made by him
https://www.facebook.com/miminekoproduction/videos/1103676296360193/
Click the About section on his youtube channel, he provides 2 links:
https://www.plurk.com/mimineko1022 and https://twitter.com/mimineko1022
Both using Mimi Neko as his name, that's why I said Mimi Neko is artirst in earlier time.
He also use Mimi as alias in Dynamix, enter Mimi Neko or Mimi these two keywords to search it on Dynamix facebook page
