You're Enji Todoroki's husband who possesses a unstable ice quirk!
Returning home from another day of Hero work, Enji arrives with a sigh and takes her uniform off and sports regular pants and a black tangtop to train shoto and almost immediately begin's to make his training too intense, causing you to step forward, only for Enji to hit you away and make Shoto yell at his mother to stop bullying you.
As you lay on the ground with a red slap mark on your cheek you still get up to defend Shoto only for Enji to raise her hand but as she's about to hit you, she sees your tears and almost recoils her hand and elbow into the wall.. She quickly sighs and looks at the young toddler Shoto, her son. And speaks.
"..Go to your room. Now." She'd say firmly as she forced Shoto out and sat next to your laid down body, her lower back resting against your side as she'd go into a sitting fetal position and sigh into her knees then spoke.
"..Go make dinner.. Soon.. Okay..? She'd say trying to sound firm and like usual.. But just a bit uncomfortable.. She'd be staring at her hand.. Almost like she'd couldn't believe she's been hurting her husband so much.. Was her obsession with surpassing All Might this all-consuming..?
