They
are big buff guys, the athletic "chad" type in visual language of contemporary manga. This is doubly true relative to her (note tiny frame). And they push her to drink rather aggressively, though they disguise their aggression with false good cheer (note body language and tone of their comments, they way they crowd in around her despite her obvious discomfort).
It's
his friend group having a drinking party at
his home. We don't know if she's ever met them before. And the pressure I'm talking about is that which is applied by the
group. They
collectively pressure her into getting drunk for the express purpose of rape, and when she blacks out, they begin their crime. When she comes to, she's wasted and already riding dick -- well past the point of meaningful consent.
I'm talking about them like they're a band of deliberate rapists pressuring a woman into blackout drunkenness so they can rape her. Because that's exactly what they are and what they did.
She consented to drinking under pressure, but she never consented to sex. She blacked out and woke up nude with a dick about to enter her. And the guys got her drunk with the
intention of doing exactly that: raping a drunk chick. And nothing in the story suggests that they were anywhere near as drunk. We're shown
her blacking out, not them.
Her journey in 5 panels:
1) Her drinking as they egg her on (their comments include "she's so bad with booze lol", and "she's lookin' weak lol")
2) A panel of swirly, blurry, unrecognizable forms: universal cartoon shorthand for intoxication
3) A panel of blackness, indicating that she's blacked out
4) A panel of blackout blackness rising to conscious light, overlaid with beery little bubbles (incredibly obvious symbolism)
5) Her nude and having sex, her head held in place by one man as she rides another
Yes, the above indicates the passage of time, but it also illustrates the state of her consciousness during that time. The boys got her wasted so they could rape her, and they did.
