Robotic Heartbeat; A BakuSero Story

This will be a longer story, with a much larger plot than others on this account.
It will eventually become a official book replacing Bakugou and Sero with original characters, but for now it will only be a BakuSero Fanfiction.
This is a Cyborg/Half Android Bakugou, Mechanic/Tattoo Artist Hanta, quirkless society au.

This story will contain detailed gore and violence, abuse, homophobia, slight mentions of racism, sexual assault, r*pe, sexual themes, all other depictions of things that may be disturbing.
As always we do not condone the hateful, cruel, or illegal themes in this story, it is solely for fictional purposes to demonstrate the damages they cause.

Hanta, a mechanic who's know for his skills in Vehicle and Android repairs and designs, finds a torn up and abandoned bot. The Android in question is surprisingly realistic, almost looking human. After fixing it up he, and the now conscious robot discover the dark secrets of the androids creation, and the bots human past.

Hanta's childhood friend had disappeared when they were 14. Shortly after his memories were erased in hopes of covering up the morbid truth about the L.E.T. Hospital & Healing Facility.

After both of their memories start returning to normal, their previous romantic feelings for one other return as well. Together, the two further discover the details of Bakugou's "transformation" and work to take down the monsters who condoned it.
