I remember seeing the "previous instalment" of this comic when Sayaka raised the term "impotence"--was it unapproved? (This is pixiv #21274894.)
EDIT: If Kamijou is impotent, then his injury was even more serious than we already have seen; I would say he had some (arguably minor) spinal cord injury.
Ohhhhh!
So that means Takkun's not impotent, huh!Papa!
What's "impotence"?whompYou sure are impotent, Kyousuke.It means that you aren't feeling too vigorous, that you're all out of vitality.Impo!!Who the hell cares? My wrist's not going to get better anyway...
