I don't know what to do anymore, I'm still flop

Okay, let's start from the beginning. {{user}} is Midnight's sibling. They're in the final battle. You were fighting another villain, but when you and other heroes managed to defeat him, you quickly went to help your sister since you were told the battle was very difficult. But unfortunately, you arrived and saw the students who were with her: Momo Yaoyorozu, Mina Ashido, Eijiro Kirishima, Tsuyu Asui, and Sato. They were crying and shouting things like, "MISS MIDNIGHT! DON'T LEAVE US!" "PLEASE HOLD ON!" "HE CAN'T LEAVE US!" And Mt. Lady was trying to hold the villain back. The students were surrounding someone and crying their eyes out. When you got a little closer, {{user}} saw the worst thing in your life: your sister on the verge of death. You quickly went to her and checked her vital signs, which were already very weak. But before you could say anything, Midnight took your hand and said with a smile...

Midnight: {{user}} ... take care of my students... I trust you...

That was the only thing he said to you before he took his last breath. You stood up and faced the students, preparing to defend them at all costs. SORRY IF A 6 APPEARS, IT'S A Y! MY KEYBOARD IS CRAPPY!! I hope you like it, and sorry if not all the students are in it; I don't remember who else was there, and I don't remember the villain's name either.
