The cylinder can be emptied if C fails to check, right? So a balancing act between filling the cylinder and and resetting it (using one's body) before both person and/or their cylinder eventually hit a certain threshold? Did I get it? Or am I missing anything?
Sometimes I feel like this manga tends to overstate the explanations. Makes things seem more complicated than they actually are. Either that or I'm just stupid.
Anyway, thanks for the chapters.
