Hmm I wonder why you instinctively chose it?
Egoist huh?? Since when? did I miss something? When could she ever be described a slightly an egoist??
That's quite the theory dear
I realize she could be talking about the incest here or homophobia, they both fit the groves rather well that it makes it hard to discern which she's on about
Sly author you
Some fire Yuri, fire chapter
The grow closer still YES
Have a nice day
Note that Yukari called herself an "egoist", not an "egotist" - the two terms have related roots and conceptual similarities, but egoist is far less pejorative. In particular, "egotism" is almost universally seen as a vice, a kind of narcissim-lite - that's probably part of the reason that whole group of words with roots derived from the latin "ego" has acquired so many negative connotations.
"Egoism" is a philosophy concerned with the self (the ego) as the motivation for one's actions - either referring to the actual philosophy of Egoism, or more broadly speaking as a descriptive term. Someone who consciously follows that philosophy would call themselves an egoist; someone whose behaviour and patterns of thinking tend to be focused on themselves might also be described (or describe themselves) as an egoist, and that seems to be the way Yukari is using the term.
In most casual contexts people fitting that description would likely be described as introverted, though the two concepts are definitely
not synonymous - introverted is pretty much neutral, whereas egoist can be used as a somewhat less pejorative version of egotist, or even synonymous with it. Someone who's introverted
can probably also be accurately described as an egoist, but outside a formal philosophical or psychological discussion it wouldn't be the word people would normally use.
Certainly I think "introverted" fits Yukari much better than any reasonable reading of "egoist" - she's clearly not overly focused on herself (no more than any other teenager), she's mostly just somewhat separated from the people around her; this is mostly due to her social awkwardness and anxiety rather than a simple lack of interest in other people. Once she engages with others it immediately becomes clear that she's definitely
not solely focused on herself, in fact she tends to put other people's needs ahead of herself (though not in a way that becomes pathological). The fact that she chose the more technical and "sophisticated" term probably reflects her fundamentally negative self-image - she's subtly (or not so subtly) denigrating herself by using a word that's technically applicable but has other, more common, negative readings.
Ironically, using the more sophisticated technical term could easily be interpreted as
egotism on her part - showing off her superior understanding and sophistication. Fortunately, that really doesn't seem to match Yukari's personality - she's not showing off when she uses sophisticated language or quotes poetry, instead she's treating her extensive internal library like a DJ sampling their record collection, picking and choosing things others have said that convey her thoughts and state of mind. She's also using others' words to give herself some distance, even a kind of plausible deniability - It's not Yukari thinking and feeling things and translating those thoughts and feelings into words, it's someone else. Her passionate (and beautiful) monologue in this chapter shows why: she values both the words and the feelings that inspired them, but
owning those words means acknowledging the feelings behind them, which exposes parts of herself that she's really uncomfortable letting others see.
Of course Shouko barely even registers any of that - to her, all the words come from Yukari even when she's quoting directly; lightly teasing Yukari with her question about who wrote those words was as much about (instinctively) lightening the mood as expressing curiosity about the source of a speech that Yukari was obviously deeply invested in. But it was also a sort of acknowledgement of the value of those words, even if she wasn't in a state of mind to do much more than listen.
As with everything in this story so far, this is excellent writing backed up by excellent translation.
