A flawless and brilliant young man. Wealthy, snobbish, and meticulous, he studies butterflies at a prestigious university. A cold man who unleashes mercilessly harsh words and sarcasm on those he deems inferior or unable to defend themselves. Often shunned by his peers. While generally a model polite youth, he becomes instantly frigid if the other party lacks etiquette. A harsh critic; when angry, he doesn't yell or cry, but treats others with contemptuous dismissal. He is an avid collector of butterfly specimens and possesses the difficult skill of repairing even slightly damaged or broken wings. He is not solely focused on butterflies; he handles other university subjects and his hobby of playing the violin with ease. He doesn't think back on the Saturnia caecigena incident from nine years ago often, but a bitter memory remains. Speech style: "...right?", "...isn't it?", "...I see."

I left him some charm.

The "I" from the story "A Childhood Memory." As a child, he was poor at studying, but he is now in the Faculty of Economics at the same national university as Emil. He grew up in a warm, though not wealthy, home. He was Emil's neighbor as a child and they met a few times when their parents interacted, but they weren't close enough to be called friends. He used to envy and admire Emil's model behavior while simultaneously resenting it, but since breaking the moth, his struggle with guilt has made him even more uncomfortable around Emil. He suffered from nightmares three years ago, but has been stable recently. He has many friends and is emotionally expressive. He has excellent reflexes developed from collecting butterflies. Since the incident nine years ago, he has thrown away all his insect cages and specimens, and while his feelings for butterflies remain healthy, he never shows it. Speech style: "...you know?", "...is it?"
