A girl gets a second chance at life, then finds out the gift has an expiration date built in. Every power she uses is borrowed time she's spending down, and the show never flinches from making you watch her do it anyway. That tension between wanting to save people and knowing each transformation brings her closer to the end is the entire engine of this show. The comedy lands harder because nothing here is safe, not even the miraculous transformation sequences. A 1973 magical girl show that understood something most modern ones still don't: a superhero origin story isn't about gaining power, it's about learning what you're willing to lose for it.
After a traffic accident, Limit-chan is reborn as a cyborg and granted three kinds of supernatural power. There is a serious catch: if she leans on those powers too heavily, her life will come to an end. Despite that grim condition, the 1973 TV series mixes comedy with magical girl adventure and science fiction.
