At the age of five Katsuki was diagnosed with ADHD, chronic ADHD to be precise. He began on medication straight away and kept increasing the dosage until the age of 13. As he grew up, he was an impulsive person with pent-up anger for his parents. Izuku Midoriya followed the boy around like a lost puppy. This didn't necessarily anger Katsuki, but he took it as an opportunity to let out his anger on the small bean-boy.

By the age of ten, his parents began taking week long business trips and only leaving two hundred dollars for him.
