Izuku Midoriya has been told his entire life that he was useless and that the world would be a better place without him. When you hear something for so long, you begin to believe it. After Izuku hits his breaking point he finally decides to go through with it...or at least he tries.
I have a tiktok if you wanna go check it out. My user is @saavaageauthor and there you will find Desperately Departing content, non-canon (and canon) angst, and more!
Gojo Satoru has spent a lifetime trying to do the right thing the right way.
He decides to spend his second terrorizing the local yakuza, reliving his middle school glory days with a pop punk youth aesthetic and a regrettable affliction for black leather, uprooting the criminal underworld and hero industry alike, and casually taking up costumed aggression as an occupation.
A Gojo Satoru is reborn as Todoroki Touya AU
Shouto’s lower lip wobbles as he cries. “M-Momma hurt me and Father sent her away. I m-miss you Touya, please come home. It’s scary without you.”
“Alright,” Dabi says soothingly while he glares at the heroes, “We’re going to my place then. Your nii-san’s going to protect you now, okay?”
Shouto is accidentally rewound by Eri’s quirk in the middle of a villain attack, reverting him to a small child with no memories of his future. Dabi takes the opportunity to bring Shouto with him to the League of Villains headquarters to remove him from Endeavor’s clutches.
“I’m glad he’s not hurt,” a man’s voice says quietly, “You said you found him in an alley?”
“Yeah,” Present Mic sighs, sounding grave, “But Shouta…it’s like I said. There was a dead dog, for sure dead. Izuku touched it and brought it back to life, just like that.”
Izuku has a quirk that goes against the laws of nature. A target for both villains and heroes alike, he’s rescued as a young child by Eraserhead and Present Mic, raised in secrecy at UA. When he eventually becomes a UA student and his quirk is thrust into the limelight, Izuku must learn how to adapt, or fall.
When his mother dies, Aizawa Shouta takes his brother Izuku to live with him. However, between dealing with the grief and Izuku starting at UA, they don't have much time to spend with their secret family...
...who decide to invade on the third day of school.
Or:
Inko dies, Aizawa and Izuku are brothers (and related to half of the League), Class 1-A finds out about the first half and Tenko is VERY protective of his younger brother.
