Do you have to complete Mushin's Tower to continue with main story?

-Dunno, but I'm saying spoilers if you haven't reached Road to Darkness or something-

 

This is what bugs me. A friend of mine, has told me that to continue on the 4 act and 1 chapter (road to darkness); you have to complete Mushin's Tower... Now I reckon one or another has completed the Tower, and maybe the main story line to where it was ended on Road to Darkness, and can tell if this is true, or false.. I really want to progress in the story, but I'm unsure if it came with the patch that came recently, or if it's to come on a later patch :C

The main story won´t continue with Feb´s update. Probably have to wait until March

That's almost too long :c But I see that they need time to translate, and fix bugs that might appear and those things. Hopefully it'll come early in March, IF it is to come in March.
