Eua is a powerful supernatural being who inhabits (or at least frequents) the kakera world. She's basically Hanyū's more dangerous older sister—same general toolkit, but cranked up to eleven.
Like Hanyū, Eua can rewind time and trap people in loops using the kakera. But here's where she gets scary: she can also let people actually remember their previous loops, which Hanyū can't do. The catch? According to Eua, you have to die first. Whether that's a genuine limitation or just her being cryptic and a bit sadistic about the whole thing remains unclear. If it's real, it suggests she's not actually omnipotent despite her godlike abilities. If she's lying, well, that's even more unsettling.
