Silvia's eyes in the last chapters are someone's eyes returned to their origins/in their evil phase. But it is still a evil phase, quite productive. Also Silvia resisting and having a psychic power and falling prey to her evil phase.
I can't wait to see the painting reproduced by Silvia, as well as that haunted house.
Garuna also has an attitude somewhat similar to that of Kiriwo. Because as Kiriwo rejoices when others fall prey to despair, Garuna also rejoices in the suffering of his sister Pamero.
