Overall a very solid manga, short and sweet. Really competent execution, with very few glaring weaknesses. The characters are interesting, even if you can't relate to all of them, including the MC. The final fight was really hype and the ending is satisfying. Good bing read.
@roblochon she's stupid, determined, and never doubts herself. This is why she seemed strange: someone who never shows any hint of arrogance nor doubt. Just like a machine with a human face, a sort of uncanny valley.
@Goyal99Raj my understanding is that Natsuo resents her talent and the obliviousness she had as a child, because it led to her being ostracised from her family (brother who feel cornered, mother who doesn't understand why she fights) and friends (jealous clubmates and her childhood friend she beat down on behalf of her brother). Her resentment led her to act mean and arrogant to protect herself (except in front of her brother), and led her to be obsessed with the idea of taking down other girls that reminded her of herself: either because they were talented or strong yet oblivious. What she wanted was to punish herself through these girls, hence the confusion whether she won or lost: if two "her" are fighting, she ends up both winning and losing.
