The Superpowered Wife's Awakening

After thirteen years of devotedly caring for her husband and daughter, housewife Elena is dismissed as mediocre and useless. They obsessively worship and fawn over the returning superhero "Silverwing," and her daughter publicly declares that Silverwing is the mother she truly admires. It isn't until the superpower grading tournament that Elena takes on five opponents single-handedly and reveals the truth—she is the real Omega-level superheroine, Silverwing.
