Curate, connect, and discover
Since Cecil's quirk has a physical component to it (his peepers) was it something he was born with or did it develop over time?
(Hehe, I love opportunities to ramble about my OC-)
It's something that developed over time! Quirks that effect the eyes run in his mom's half of the family, so it was kinda expected to eventually happen tbh. His quirk discovery happens at around four years old, and with continuous use of his quirk his eyes began to change. His pupil turned almost translucent, the color in his iris spread to his sclera, and eventually the pigment faded to a veiny red. It is unknown exactly why Cecil's quirk affects him this way, though doctor's theorize it's either an inherited side affect from a relative's quirk, or the melanin in his eyes is naturally dissolved in the process of showing someone their own memories.
