User blog comment:FairyRaven/Fairy Tail Chapter 328: Zodiac, Review and Commentary/@comment-5840892-20130419171013

This was an interesting chapter; first we get to see how you can use the Twelve Zodiac Keys all at once, and how you potentially open and/or close the gate. And at very the very end; we get a AWESOME shot of Natsu looking like a Boss.



As for the number 7, and that reoccuring date of July 7: According to some myths and legends surronding Magic; the number 7 is the most powerfully magical number. And that the day when Magic is at its strongest is July 7th. To precise; it is the 7th Second,of the 7th Minute, of the 7th Hour, 7th Day, of the 7th Month that is supossedly the most powerful instant in the year for Magic. Hiro is just using that legend as a plot device.
