This chapter raised some trauma flags for Hizumi that may explain why Hizumi is the way she is (although her abyss'd and lifeless eyes may have been a big hint since ch1). The talk with that gyaru awoke some hateful memories based on the "Goodbye, Hizumi" panel and the pitch black panel with just text bubbles it seems (side note. Those panels make obvious the author is a Boy's Abyss fan. Those flashbacks looked a lot like those Nagi began to have in Tokyo. IIRC, he said on twitter he's a big fan of Ryou Minenami works)
Although this chapter leaned more towards the romance tropes in the end, the relationship seems to be moving forward quite fast. And for those who haven't read the spoilers, Uzume Miyabi, AKA Not!Kana finally makes her appearance and will defo throw a wedge. She has a quirk: her earrings emote alongside her For RAW readers, the aftermath of Uzume's rageful and tearful confession during her fight with Hizumi and Shinba's reaction will be released this week
PD: Lmao at the cut down final part of the translators afterword.
