Hanlon Hoshi, or Pro-Hero Starlight, is a member of JOSEI, 4 Japan-born, top 25 internationally ranked, pro heros who fight crime in America. After their idols, the Wild Wild Pussycats retire, they return to their homeland to take their place and fight the growing threat of the terrorist group Hero Crushers, who have vowed to destroy all heros and their society.
For Hoshi, the only thing on her mind is finally making the Japan Top 10, something she's wanted ever since she was little. However, she finds herself competing for a spot on the Top 10 with hot-headed hero Dynamight, or her good old junior-high pal Katsuki Bakagou. When these two childhood 'friends' reunite, will stars and sparks fly? Or will they crash and burn?
