Ai Enma
Ai Enma is the main character of the series—a spiritual entity with striking red eyes and long flowing hair who carries a genuinely tragic backstory. She lives in a perpetually twilight world with her grandmother and runs a revenge service where she takes on clients' grudges and delivers vengeance on their behalf.
Day-to-day, she wears a black sailor uniform, though she switches into a floral-patterned kimono whenever she's actually carrying out a client's revenge. The contrast between her everyday look and her vengeance outfit is pretty intentional—that kimono marks a shift into something darker and more serious.
What fans often note about Ai is how the character design communicates her nature: those red eyes and that long hair make her immediately distinctive and somewhat otherworldly, which fits perfectly with what she actually is. She's not quite human, not quite ghost, existing in that liminal space between worlds that defines the whole series.
