Attack my hero (Attack on titans X Boku no hero academia crossover)

As humanity won against the titans, they also lost very important people as well....

Mike Zacharias. Mike was a squad leader and a trusted soldier. He died protecting his girlfriend, Hanji Zoe, but she died weeks after his death.
Hanji Zoe. Hanji was a mad scientist and a squad leader. She loved titans but not as much as she loved Mike. She died by the beast titan when she was distracted by his words about Mike.
Erwin Smith. Erwin was the commander of the survey corps. He loved his work and making plans that could help humanity win against the titans. He died protecting his comrades and more importantly, his fiancee, Levi Ackerman.
Levi Ackerman. Levi was a squad leader and humanity's strongest warrior. He had an unhealthy obsession with cleaning but I guess that can be blamed on him growing up in the underground city. Levi died after killing the beast titan by his suppose dead uncle, Kenny Ackerman.
Eren Jaeger. Eren was a member of squad Levi and was humanity's last hope. He grew up with Mikasa Ackerman and Armin Artlert. He was killed by the King due to him "having" a titan within him at birth.
Mikasa Ackerman. Mikasa was a member of squad Levi and she was a relative of Levi. She was adopted by Eren's family after her parents died. She was killed by the military police when she tried to stopped Eren's death sentence.
Armin Artlert. Armin was a member of squad Levi and is Eren's and Mikasa's childhood friend. He was killed along with Mikasa since he tried to stopped Mikasa from going to a dead Eren.

These 7 heroes was reborn into another universe, Boku no hero academia. They were born with quirks, instead of titans. Now Erwin, Mike, Hanji and Levi have to stopped villains and joining UA can help with that.
