How to Keep an S+ Score in Special Mission 5 (Boss Rush Stage)

Ever since the 1.2 update for the 3DS version of Gunvolt was released, I've seen a fair amount of people wondering how you can maintain an S+ score in Special Mission 5, the boss rush stage. There's no denying that this can be a pretty tricky thing to figure out, what with the true final boss and all, so I've decided to detail the method I use to ensure that I obtain the most amount of kudos possible in the stage.
As a quick note, this post will presuppose that the reader knows how to avoid most, if not all of the boss attacks. With that said, you can read my strategy below.

"Nova's Memories" Drama Track Translated

Eclipse5632 aka "Sensei Hanzo" has just finished translating the second audio drama track for the "Justice Rage" album. This track details Sumeragi's "Project Gunvolt" tests and their struggle to find a test subject compatible with the electric septima gene. It's a short track, but provides some interesting info, such as Nova's last name being "Tsukuyomi". Also, unless I'm completely off the mark here, I think "Takefutsu" (whom the scientists speak of) is revealed as the real name of the true final boss. It's crazy to hear in this track that Nova's compatibility with the gene was predicted to be even higher than the true final boss, though!

Anyway, in addition to translating this track, Eclipse also provides some intriguing translation notes in the description of the video, so check that out, as well!

Who Was The First Azure Striker?

As you may or may not know, in the JP version of Gunvolt, the true final boss (whom we won't mention by name here to avoid spoilers) mentions something very intriguing about the origin of the Azure Strikers in his battle dialogue. According to him, the first adept with that power was discovered long ago, deep in a South American jungle. With their septima, the "Azure Strikers" were able to control electrons at will, allowing them to conjure powerful bolts of lightning to attack, and move swiftly by manipulating magnetic fields. What made their ability most important, however, was that they were able to freely control electronic devices. It was apparently the ultimate power in an age dominated by electronics.
