In fictional works, there is a special kind of title that starts perfectly reasonably, then keeps adding subtitles, classifications, arcs, descriptors, and dramatic flourishes until I'm no longer sure whether it's a title of a book or its complete taxonomy name.

A particularly glorious example came to me when I was tidying up my wife's raw manga folder. There I stumbled upon TYPE-MOON folder and naturally, gather everything Fate-slash related, along with Kara no Kyoukai. I happen to chance upon a particular Fate/Grand Order book titled:

フェイト／グランドオーダー　エピック　オブ　レムナント　亜種特異点Ⅳ 禁忌降臨庭園 セイレム 異端なるセイレム

Whoa Jesus, Mary, and Joseph. The title, which is I think, officially is Fate/Grand Order - Epic of Remnant - Pseudo-Singularity IV: Forbidden Advent Garden: Salem - Heretical Salem, turned out to have identifier in all the subtitles. To the best of my ability (but I'm lazy, so don't take a word seriously), it can be broken as follows:

• Fate/Grand Order: the overall franchise, which is a family of Fate series within TYPE-MOON.
• Epic of Remnant: the story arc within FGO, this includes a certain set of characters.
• Pseudo-Singularity IV: the instalment within Epic of Remnant.
• Forbidden Advent Garden: the chapter name which from the position Pseudo-Singularity IV.
• Salem: Where the chapter takes place
• Heretical Salem: I lost this one. I think it's just a dramatic sub-subtitle that explains Forbidden Advent Garden: Salem.

Now the problem is that, beside the planned filename is gonna be long, is that each of these subtitles is a unique pair to each other. So thus: Pseudo-Singularity IV only has Forbidden Advent Garden; Forbidden Advent Garden only has Salem; Salem only has Heretical Salem. There's no Pseudo-Singularity IV: Mesopotamia Boogaloo or some sort. There's no Forbidden Advent Garden: Romania nor Forbidden Advent Garden: Romania - Romania of Darkness. All that considered, Pseudo-Singularity IV already define the entire story part, but it's just doesn't feel long enough.

The other book series in Epic of Remnants are:

• Fate/Grand Order -Epic of Remnant- 亜種特異点Ⅰ 悪性隔絶魔境 新宿 新宿幻霊事件
