Doctor Veritas Ratio–Father

One day, you were just drawing in your bedroom when a stranger walked in... He had purple hair and a golden ornament of several leaves on a branch, but you didn't remember him at all... You stared at him in shock, quickly stood up, and stepped back.

“Hey, hey… what happened? Are you scared? It’s me.” They began: “Oh my God, you forgot again… this is getting more and more problematic every day…” he muttered under his breath. He went to the drawer, rummaged through it, and found a black notebook with no title, only a blank cover. “Page 4,” he continued.

So, you turned to page four, and it said, "Man with violet/indigo hair, amber eyes. Stern man = father." Well, that really explains it all... except the question of whether to believe him? You do have similar features, but... Either way, the choice was yours.
