As she does, the mushi inside of her is lured out from the moonlight. As liquid pours out, Ginko sees the mushi coming out and tells her to close her eyes, which makes the liquid return to her eyes, but Ginko catches the centipede-like Mushi. He explains her eyeballs are gone and take out his fake glass eye and injects it with the liquid Mushi. He then places it into the left eyesocket of Sui, causing a pillar of light, but allowing Sui to see with that eye. Biki and Sui continue their lives normally, while Ginko heads out towards another mushi case.
