Kekkaishi Vol. 4 (manga)

Sibling rivalry surpasses the bounds of life and death itself when Yoshimori discovers secrets of a ghostly patissier's past life. The fraternal theme continues when Yoshimori's older brother Masamori returns to Karasumori. Everyone seems to respect and admire Masamori--but Yoshimori feels alienated and left out in the cold. All this and more ayakashi to catch and cakes to bake--what's a young kekkaishi to do?
