Ryuko vs Satsuki sketch and previously un shown color variants from the cover for the short comic done back in October 2013.
Some artists want their works to last forever, but Motoi Yamamoto compares his art to an arrangement of fresh flowers — it’s alive to enjoy for just a short period of time, and then it becomes a beautiful memory.
SAND PAPER FLOOR ROOM
So basically it’s a torture device, where a person is put into a room with slow moving sand-paper at the bottom. There is no way out.
The person has to walk forward to keep from getting send to the corner and scraped.
Eventually after days of walking, the person will get tired and won’t be able to anymore.
What happens next, is pretty gruesome and self-explanatory.
