 For Kawai, like in "Séraphîta", the "union" of masculinity and femininity in the siblings is "something divine", although it is not as clear in "Torikaebaya" as it is in "Séraphîta".Pflugfelder describes the siblings as "quasi-divine", drawing a parallel with the Dragon King’s daughter from the Lotus Sutra, who by her devotion to Buddhism transforms into a man and begins to teach the Dharma.Kawai notes that the siblings cannot be "properly united as they are not lovers or spouses".
