Silent TearsEpisode 4

Seraphina, a six-winged seraph, is framed by her adopted sister Aurelia and tortured to death in the abyss by demons. On the seventh day after her death, her spirit witnesses her parents caring only for Aurelia, indifferent to her disappearance. When they finally recognize her shattered remains, Seraphina fades away in utter despair. Reborn from hatred as Astraea, an eight-winged judgment angel, she returns to repay every torment a hundredfold. After settling all grudges, she turns into stardust, leaving her eight-winged power to the orphan Lilith to inherit new hope.
