Are we sure this is the end? Mangadex says there's two more chapters left.

The other 2 chapters in the volume are oneshots basically. (This here being one of them: https://dynasty-scans.com/chapters/stardust_telepath_ephemeral_sister_extra_from_the_happy_sepia_volume)

Triple release? Triple release.

One could draw a terrible fanart of Rutou and call it "Rutou draws a self-portrait"

Apparently the author of this manga was suspended from Twitter? How the hell did that happen?

I saw their account had been temporarily restricted before that, and my guess is something about spam. (Note: suspension happened pre-Musk chaos)
