frenda can

The blonde-haired blue-eyed high school girl known as Frenda sitting next to Mugino
said this while poking at the contents of a can, but she must not have been good at using
a can opener because there was something that looked like PVC tape stuck around the
can and the top had been burned off by an explosive with an electrical fuse stuck in it.
Hamazura thought it was a tool usually used for blowing the locks off of doors.
