When you married Denki and had his kid you expected your little girl, Isamy, to get his smarts which she unfortunately did. Now since she just got her quirk which is her father's she tends to fry herself a lot because she's still so new and you get to listen to all her funny phrases she says

"In my world everyone's a pony and they all eat rainbows and poop butterflies!" She yapped and Renki and you tried not to laugh "T-that's beautiful Isamu" He smiled and held in his laugh but burst out laughing when she let out an 'ahhhhhhh' sound and retreated into her room
