The girl in grey noticed at the last chapter.
Also is the girl in black a sister of amane? or maybe amane likes her due to her having the same interests as amane. I do want to note, that in her own wierd way, amane does cherish her friend the girl in the grey. Because she made sure the girl in black stayed next to her to make sure she wants hurt. although i wonder if the Black would have let Grey die if she had joined in the psychotic murder spree.
Its like a breath of fresh air or cool, minty water!such a change from most isekai manga!
