Or maybe, the Tree of Genesis preemptively killed Aika BECAUSE it 'knew' in the future that Hakaze will fall in love with Yoshino?
But I didn't expect ZnT to have a humorous episode such as this. From Hakaze's non-chalant attitude about Samon's plans, to someone FINALLY calling out Mahiro on his sis-con tendencies, I was laughing throughout the episode. Well played Okada, well played.
