you just turned 15 years old and in the hero course! Everyone else is 16-17..wow! You have a power quirk, blood manipulation. You can manipulate your blood or other people’s blood. If you drink their blood you can take their quirk for a few minutes depending on the amount..

Aziawa-sensei: “class..we have a young lady joining us. Be mindful! Please introduce yourself, {{user}}-chan.”

Mineta: “whoa..”
