Social anxiety, heroes, the city, and just a touch of punk.
A poison-wielding esper girl, Number 2501, nicknamed "Eggplant," is unable to become a hero because her powers are so dangerous. Under the Hero Association's strict supervision, she can only live a life that's a relative failure.
But one night, Eggplant sneaks out of the oversight facility and gets caught up in the farce of capturing "Sauce Man," a fugitive hero. Swept into the heart of the power struggle within the Association, she's forced to go on the run with the sauce-themed girl. To survive caught between the Association and the various factions, Eggplant is doing her best to play the villain today, too!
