Doesn't Touka's appearance also have to do with her fitting the motherly bill for Sensei? She looks pretty similar to to Saki(long black hair, giant chest, etc.) and we know she didn't like him (Saki) very much according to Yasu. Touka's wholesome nature along with her appearance is what probably makes Sensei see her as a maternal figure even though every important female figure in his life has/ or wants to fuck him. And I think Yumi may have fit that bill also if she didn't call him "douche monkey" and whatever creative nicknames she came up with for him that I can't think of right now all the time.
Tangent: Has there been a clues given as to what the other name Parold E. Dolia(correct me if that's not the right god) knows Yumi as? Since its been revealed in Chapter 1(I think) there really hasn't been any clues or hints given as to what the name is.
Saki actually seems to be a brunette:
Her bust size does probably come into play in his mind, though.
As for the name Pareidolia knows Yumi by, it hasn't been revealed as far as I recall.
Thank you for actually referring to the source, as right now I'm unable to put enough effort for a proper research myself.
It's nice to see the story is aware that it forces a motherly role onto Touka instead of Touka just becoming a good mommy on her own solely through interacting with Yasu and Sensei.
My criticism is not about mommy-Touka being a turn that doesn't make any sense narratively. No, it kinda does. It's just that it feels somewhat rushed and undeserved. I just can't see how Touka simply damage-controlling Yasu's shenanigans would make Sensei think "hmm, I want her to be my mommy". As I see it, for this transition to be more believable, we would need more mature behaviour from Touka, more gradual shift in how Sensei views her and more resistance from Touka against others imposing this new role on her. But she just kinda runs with this weird new development for no reasons other than this would be convenient for the story. And not only she does it, but other main characters like Ayane (not even involved in her arc) start parroting the word "motherly" and it makes them look like mouthpieces in the hands of the writer who wants to push a certain narrative. Which is what all writers do by definition, but in the moment it becomes obvious, the magic fades and bad writing becomes apparent
I don't think Yasu matters that much when it comes to Sensei seeing Touka as a motherly/matriarchal figure.
That seems to mostly have started in her 'Kryptonite' Chapter 3 event where Sensei dumps his relationship issues on her and she literally tells him he needs to grow up:
This was after she gives him a place to stay, and finds out about his Maya and Makoto relationships on top of Chika, etc. Sensei came to Touka with his problems and she genuinely tried to help him see that he's acting like a child.
Besides simply being honest, she's also known for her compassion. Hence why in her 'A Brief Moment in Time' Chapter 2 Event, she's crying for those in The Old District and feeding a random homeless old man in front of Sensei:
In her last Chapter 2 Event, Touka claims she has accepted Sensei and knows he has a heart:
Throughout Chapter 3, there's some comparisons made between Touka and Tsubasa by Sensei, and of course the whole maternal urge stuff.
Still, by the end of Chapter 3, at the Halloween party, she's simply letting herself fall into whatever role Sensei needs, because he looked like Yasu:
She's not really trying to be his mother figure (and likely doesn't want to), she's just being honest and showing compassion, which leads to Sensei seeing her as one.
As for Ayane, well, she also doesn't really have high standards in the first place. Her actual mother ditched her. Simply showing compassion and having boobs is probably enough for most in this game to consider anyone motherly.
Although, Touka
has been raised and trained to mother at least two children simply out of tradition, for the empire she'll inherit, and there's not really anyone more mature or generous, around.
I wouldn't really consider this as being bad writing. My only real critique is that choices seem to deprive the story of certain consequences, albeit that might be the point.
