Terminology

Terminology (ターミノロジー, Taaminoroji) is a page that explains the various words and phrases that Raindrop uses to describe her work and characters.
== General Terminology ==
=== Positive, Negative, and Final Derivatives ===
Throughout Raindrop's various works, a Derivative (デリバティブ, Deribatibu) refers to a state of emotion so strong it changes a characters appearance, voice, and mental state. 
As implied, Positive Derivative refers to alteration from 'Positive Feelings'- traditionally positive things like happiness, excitement, gratefulness, and love, but for the more unstable individuals, things like obsession, sadism, and pain and so on can be twisted into creating 'positive' feelings depending on the opinion of the character experiencing the derivative. Traits such as sparkling eyes, hair growth, cartoonish blush, and a flowy voice are common, but it tends to be character specific.
Additionally, the inverse is also true- a Negative Derivative refers such an alteration from 'Negative Feelings'- yet again, things considered traditionally to be negative like melancholy, disappointment, resentment, and hatred, but yet again for the more negative/unstable individuals, things like happiness, personal misfortune, and the success of hated people and so on can be twisted into creating 'negative' feelings, the criteria once again depending on the opinion of the character experiencing the derivative. Traits such as eyes loosing sparkle, hair becoming darker/messier, sudden/heavier eyebags, and a softer/more tired voice are common, but it overall tends to be character specific.
Final Derivatives, however, are usually reserved for Main Characters, though aren't reserved. Final Derivatives are for only the most extreme of mental states- things like loss, tragedy, wanting to disappear or trying to, and other extreme emotions are things that can cause this. It's intended to represent 'the worst thing' a character can go through, or otherwise breaking into their limit, hence the name 'final', as in the final state of consciousness.
== Series-Specific Terminology ==
=== Angels × S ===
==== Wing 0, Wing 1, & Wing 2 ====
Wings of Angels × S, which are sometimes abbreviated as W0, W1, and W2 respectively, refer to increments, of time, roughly 1 Japanese schoolyear apart from eachother. Wing 0 occurs in the 2nd Year of Junior Highschool, and is the prequel to Wing 1, which occurs in the 3rd Year of Junior Highschool, and the final year, Wing 2 is the sequel set in the 1st Year of Highschool. 
===== Wing 0.5 & Wing 1.5 =====
There are some exceptions to the rule, such as Wing 0.5 and Wing 1.5, which refer to the summer breaks inbetween the regular Wings.
==== Schrodinger's T-Swag ====
Schrodinger's T-Swag refers to a hoodie worn by Fumika, one of Raindrop's Original Character from Angels × S. The reason it has such a unique title as opposed to other characters outfit's, such as Koriko's Cardigan, belonging to Koriko Chounabayashi to match Himeko's Cardigan, or Bansoko's Cardigan, belonging to Bansoko, is because of a comment Raindrop's Assistant made in person wondering if it would be T-Girl Swag, because Fumika wears it, or T-Boy Swag, because he said he wanted to wear it as well.
==== The BitchBastards ====
The BitchBastards, also spelt The Bitchbastards and sometimes simply referred to as 'Bitchbastards' generally references the friendgroup between Himeko Hachimitsu, Koriko Chounabayashi, Ayaka, and Hasumi, but can change depending on the context and time relative to the series. Sometimes Koriko is omitted from the phrase, and at other times it refers to only Ayaka and Hasumi. 
=== Shinitagari Shoujo Terminology ===
=== Season 1 & Season 2 ===
Seasons of Shinitagari Shoujo are sometimes abbreviated as S1 and S2, and work as expected, with Season 1 and Season 2 happening roughly 3 years apart.https://twitter.com/RAINDROPPI_042/status/1749827432671023381 Season 1 of Shinitagari Shoujo is sometime inbetween Wing 0 and Wing 1, and Season 2 is roughly 3 years later, occuring the year after Wing 2 of Angels x S.
=== For The Train Station of Dreams Terminology ===
==== Being Fukouver ====
Being Fukouver, also sometimes just said as 'Fukouver', references Fukou Fuyunami
, one of Raindrop's Original Character from For The Train Station of Dreams. It's a pun on her alias, mixing "Misfortune/Misfortunate" (不幸/Fukou) with the english word "Over". The expression is shown to be used in both negative and positive situations, making the true meaning unknown.
== Trivia ==
* Raindrop stated that the name of Wings for Angels x S was chosen not only to evoke mental imagery of wings, such as the wings of butterflies, birds, and most notably, Angels (as a reference to the title) but the theming of Hospital Wings/Units as well, and was finalized when Raindrop's Assistant said he liked it in an in-person conversation back in April 2023.
