Title Fix: Hand-delivered by YMY Herself

Our latest Title Fix has the creator herself clarifying her intentions in setting the title. That is like the best authority we could have, right?

Subsequent to the latest Namco Taiko Blog from which one of the addition was a complete YMY-only challenge in Ranking Dojo Gaiden,YMY herself (@yyyamamo) has retweeted the announcement tweet, while adding a bit of lore of her creation:

そういえば「ザストゥールの魔導書」の「ザストゥール」の語源について話したことがなかったで話してみようかなと。元々はクトゥルフ神話に出てくる「ハスター（Hastur）」からですがどこかの解説に「Xastur」とも記載しているのを見て、「ザストゥール」と発音を変えたのが名の由来です。

"Speaking of, since we haven't talked of the etymology for ザストゥール from ザストゥールの魔導書 so here are a few words. The origin can be found from Hastur from Cthulhu Mythos, which from a certain source it is also denoted as "Xastur" and changing into such pronunciation."

With respect to her reveal, we will also change our denotation accordingly:
ザストゥールの魔導書 Zastohl no Madousho → Xastur no Madousho
