Erasermic dads
What im thinking is that they got married and decided to go to someone who can create a child with their dna using their quirk (if they want more, they adopt (eri and shinso)). Yn came out as a baby, has Aizawa's eyes and mic's hair. They loved her from first sight. Yn is quiet, but positive. They're more talkative when they know and trust you. When yn is mad, she'll give a glare that proves they're Aizawa's kid. Yn has a combination (most likely), one or the other, or both quirks. Yn has Aizawa's love for cats. When mic is being weird, yn tells Aizawa. When yn hears that they're getting siblings, they celebrated. Yn calls mic papa and Aizawa dad.
