Fellas the episode is good and there were lots of cute moments with Nao and Ricchan and Aki was super hot but there was one glaring problem I picked up because I decided to read the novel. Novel thing under the spoiler if you want to read it yourself as blind as possible, but it's relevant to the episode
in the novel it is explicitly stated that Hayase and his goons beat him up and kicked him everywhere, but especially targeted the legs
So I don't get it at all why they would change this. How does this escalation even make any sense if in the anime it was a clear accident?
a bit off-topic but the anime keeps the pace by cutting out Nao's internal dialogue, which is like 80% of the novel. here's a tiny bit of the scene where they paid respects to the deceased fan

it's well-written and is overflowing with random details she cherishes or is annoyed by, so give it a try if you're interested in the story!
Considering Shuya and Sunao's poor self-esteem, it feels like we're transitioning from the fear of the replicas getting disappeared by them to the originals wanting to go away themselves.
I wonder whether there's any effect when the replica "dies" rather than being disappeared by the original. Maybe there's no lasting impact to the replica, but there's just no dead body?
Hayase said it was an accident, but that was obviously a lie.
I had a brief glimpse at the manga and it seems the anime toned down a lot, but I kinda like way the anime does it. It's more grounded.
like i wrote in the thread post, the anime changes heavily what happened in the novel. i had a little crashout about it tbh, it annoyed me so much.
in the anime hayase goes from "we were arguing and pushing each other - now that i've lost a bullshit duel he challenged me because of an accident, i'm gonna murder him" which does not make any sense
in the novel he goes "i had my homies with me and we beat this asshole up until we heard his bones cracking, and now that he couldn't stay put, i'm gonna teach him a lesson for good" which is him being insane from the start and continuing to be so
the anime also undermines the theme of appearances as being furthered by the distinction nao makes between a "violent person" and a "gentle person" (as was her only argument at the end of the festival). there were 2 boys she was afraid of at the start (you could say they were identical to her, heh -- there was a lot about her fear of boys in the novel -- she described them both as attractive and simultaneously scary at the start), and only after talking to them and seeing them act she distinguishes them as completely separate people (just like her and sunao)
Why do you think it was an accident?
Even in this version, Hayase is a person that is capable of purposly hurting other people. It absolutly makes sense that he takes revenge on Sanada for beeing exposed to the whole school. Even if he claims that it was an accient, who is gonna belive him? He already has a bad reputation as it is. He still comes off as an insane criminal, at least in my opinion.
I understand that you are angry the anime changed so much. Maybe I would be too, if I would've read the LN. But to me, what you describe sounds a little bit over the top. If Sanada was beaten up, how did he explain this to the teachers? I'm not sure I would've liked that version as much as I am currently liking the way the anime went with the story.
As for the last part of your post, I don't understand all of it, so I can't really comment on that part.
what happened at the stairs was portrayed as an accident, because we didn’t see a deliberate push, and hayase looked stunned for a moment when he saw sanada on the ground, and then he figured out it’s good for him
hayase’s reputation was as good as it could be UNTIL he beat up sanada with the other guys. he was described as “very popular” before the assault. every party denied anything ever happened, so the school was not involved. but if testimonies are good enough for teachers, it doesn’t fly with the students, because i suppose they could not avoid being seen.
so in the novel, there never was any question about the legitimacy of the duel and the claim that the injury was hayase’s fault, and STILL the majority of the students were like, “oh, if this is happening, so i guess it was true???”
you tangentially touched on his design, saying, “who is gonna belive him? He already has a bad reputation as it is. He still comes off as an insane criminal”. this is validating me on another point that i didn’t mention on the forum, but in short, they streamline the designs at the cost of, again, the themes of the work.
about hayase’s design
in the anime he looks like matou shinji (wavy colored hair, narrow eyes, lines under the eyes) + the piercings make him look like a delinquent.
in the novel he, on the surface level, is absolutely identical to sanada (for nao, of course). they induce in her fear of men both with their appearance and their behavior; they are both tall, and very good-looking (nao describes hayase “looks like a model”, and ricchan just straight up “hot guy”)
this is another point of reference for the theme of appearances in the novel, and how those appearances do not correlate with what a person truly is
sunao - nao is expressed in the anime, the boys progression is roughly:
hayase - a handsome guy and a very good basketball player = sanada - a handsome guy and a very good basketball player
—>
hayase - a violent person != aki - a gentle person != shuuya - a morally ambiguous person
i’m getting sadder and sadder with this adaptation…
