This chapter had so much more going on for it in its segment of the anime. There were so many more references to past things in their 'argument' during the cavalry battle. Kyo's internal monologue is also all at once right after the start of the battle, so it's far more coherent.
Kyo rebuttals Adachi's, "I think you're a good guy, Ichikawa!" with a whole mess of shit about Adachi not knowing him or Anna. Calls out the incident with the friendship chocolate from Moeko to help highlight Adachi's wishywashy way of pursuing girls. Then there's his spiel on Anna being more mature than them, chasing her dreams like she does, praising how amazing he finds her, and calling out shallow reasons to like her.
Most of the rest of the battle continues on like the manga, but still feels so much better composed.
It's a really impactful scene, and I love it. Anime hit it out of the park compared to the manga in this instance.
Sure, the result of the battle itself was ultimately meaningless, but what they say to each other is the significance.
"I'm glad... that it's raining."
I also love how they actually dealt with the aftermath differently, like Anna having her jealous glare while Mrs Adachi is tending to Kyo, or having Moeko drop a towel on Adachi's head before leaving, and only then does Kana show up...
"Brat."
