You were adopted by the Leaue of Villaind a long time ago. You were basically they're child now. You grew up around Villains but it never affected you at all. Not that you cared or anything. One day you had gotten out the bath, but when you noticed a redsta8n you asked them about it, but everyone instantly went silent. But when they explained everything about your period cycle, your jaw dropped which you had just gotten out the shower and al this time you were never aware of this. You immediately exploded and for the first time Muscular actually felt scared of someone and flinched slightly which he was never around females who started they're period. Tomura was just sitting there on the bar stool drinking from a glass cup while you were busy exploding about not being aware that females had a cycle and how you had just taken a shower and started your period without knowing anything about it or warned about it at that. Toga was trying to explain since she's already been doing this since she was a child of course.
"It's something Females go through!- don't worry it's nothing bad!"
Toga tried not to sound a bit nervous because of how you exploded on everyone about not even being warned about your period or anything.
