I think Reaper sometimes notices unusual things near Geno, for example, heat from an accidental touch, in this case, steam from a temperature difference (Reaper is not as warm as Geno, so it must be very cold for steam to come out of his mouth)

Killer did not need protecting, but simply knowing this was not able to quell the prince’s impressive LV-induced agitation.

old crosspost on my mind again 🩵💜 AU where errorink is new to existence. their spaces combine and result in a long glass pane between them. they're unable to hear or reach the other, so their only means of communication is writing & drawing.

Partial review of a piece for Live, Laugh, Bone (A 2026 Fontcest Wall Calendar Fanzine). The piece is by Lia and shows Xtale Papyrus and Xtale Sans cuddled next to each other outdoors. Papyrus is pointing at the sky. A golden butterfly is visible. Preorders open July 30 through August 27 at livelaughbone.bigcartel.com

Wowie, who needs to pretend airplanes are shooting stars when you've got the real thing?

I've been learning how to draw backs
