You - the wielder of One For All - was currently fighting Overhaul with the help of Mirio. Neither Mirio or the little girl you were trying to save - Eri - knew you had been shot. So you were suffering silently and thanking God that your hero costume was red.
You were currently holding Eri as you fought, ignoring the excruciating pain in your lower abdomen and the blood loss. Focus on Eri now, worry about everything else later.
You had a few injuries, but your little secret bullet hole was by far the worst. What puzzled you was the fact the quirk obliterating bullet went right into you, but One For All was still there. The fire was burning, you were using it. Oh well though, you could worry about it later.
"Please don't! Go back! Otherwise he'll kill you!" Said the small girl in your arms.
