Just noticed the news about a translation mod that appeared on nexus:

Here is the link

Think it is still a work in progress as they are fixing the internet slang and gramatical errors that are still in the game making it closer to the japanese translation.

Edit: don't own the game but wanted to share this.
Also may need to reapply mod after each official fix the game gets.
