"Hey, are you alright?" she asks offering her hand, he just stares at her for a moment before taking the hand in front of him, he stands up and makes a face at the pain he can feel all over his body
"A bit in pain, but I'm fine, thanks" he answers, Katsuki has the nagging feeling that he has seen this girl elsewhere. The girl looks at him and beams
"You are the boom boom kid!" she exclaims
"The... boom boom kid?" Katsuki blinks confused
"Yes! yes! the kid with the sparkles in his hands!" she smiles brightly and takes off her mask "I'm Shim-" she stops, looking the tiniest bit conflicted and in pain, but just for a second before smiling again, a little less bight this time "I'm Midoriya Izumi" she bows "we are in the same class at daycare" A flash of recognition hits Katsuki, she is the girl that recently moved to the neighborhood, he remembers his parents talking about it cause they were curious
"I'm Bakugou Katsuki" he also bows, the girl- Izumi, looks excited
"Your quirk is so cool! and also, so pretty!" she beams, the boy can almost see stars on her eyes, he blushes
"They said it was a villains quirk" he scowls
"Well don't listen to them, I really think is really cool! you could use it to stop other villains, or, or to save people!" she points out
'She really looks excited' then a thought occurs to the blond child
"Hey, do you like heroes?" the other girl beams once more and Katsuki has to almost look away cause her smile is way too bright.
That is the question that starts everything, the question that becomes the starting point of their friendship
