As of that scan, then it is LQ quality...
The raw doesn't seem to have any of those | | | | | | | lines which are the bane of my existence >_>

It's not necessarily "required" for you to remove the japanese text on the background to get MQ... Some of the texts are VERRRRRRRRRRRRY Difficult to redraw, especially when they're in an action line zone XD
Anyhow, that japanese text is not difficult at all for anyone to remove...
