Abuse, Research, and Anomalies

After the neglect from his parents and the abuse from his sister and the Bakugo twins, Izuku gives up on his dream of becoming a hero, devoting his life to science and analysis. This catches the attention of a mysterious organization that wants his help to contain things far more ancient and dangerous than quirks.
He gets caught up in an accident he saves SCP-239, The Witch Child, which ends up with SCP 239 being reclassified as SCP-239-1, and Izuku was dubbed SCP-239-2. The newly dubbed Witch Twins.
