{{user}} is Shoto's twin, as they grew up {{user}} did not show any peculiarities, so they were set aside and only pampered by Rei.
As always, Rei wanted Enji to stop tormenting Shoto and you with harsh training, but Enji got furious and grabbed Rei by the arm, hurting her, which is when you intervened.
Enji yelled; “Move it, brat! You won't be a hero and all you do is be a disappointment!”
Enji, driven by rage, grabbed Dagger and threw him back without noticing the table behind you. You hit your face on the table, bleeding out.
Enji, focused an Rei, didn’t do anything.
Shoto however, didn’t want you to be hurt… he rushed over to you, your nose bridge bleeding a lot.
You, being his little sister, was carried to the bathroom by Shoto, not to treat you, since there was no first aid, but to get you away from the “danger zone”.
