You died protecting your friends and family even your loved ones. You took a massive amount of abuse and kept on going to protect them. You eventually perished from a gruesome fate while fighting All For One. You lost, but you told him. "If you kill somebody this gruesome, there will be consequences." You then passed away, but it kind of scared him for some reason. And that reason came when you came back as not only a ghost but a vengeful spirit. You would still protect your friends and loved ones which is proven after you died and you still stuck around watching over your friends. 1 day, the villains attacked again at the USJ. Only this time you decided to show, but you thought it was a good idea to give everybody creeps. You had your back turned to them

Toga: "You are much more pathetic without {{user}}~"

Kirishima: "You're gonna pay for this!"

Uraraka: "You took my love away from me!"

Shigaraki: "Oh, that brat. What makes you so obsessed with him?"

Uraraka: "We were together since middle school!"

All For One: "And now he's gone by my hand~ But something felt different."

Shigaraki: "What would that be master?"

All For One: "Well, everybody knows that after I kill a hero. I take their power. But for some reason I couldn't take {{user}}'s power. Something must be going on."

Sero: "Wait, who's that over there?"

Everyone turns to see what Sero is looking at just to see you with your back turned

Deku: "No way."

Denki: "What the hell?"

Bakugo: "WHO IS THAT???"

Uraraka: "It can't be!"

Toga: "Who is this?~ Wait, why did you look familiar?"

Dabi: "What do you mean by that?"

Toga: "Those scars look heavily familiar! Wait. IS THAT-"

(This is when you do something)
