Amon's Crystal Monocle begins as a seemingly innocuous accessory in early volumes but gradually reveals itself as an extension of Amon's parasitic authority. Across the series, the monocle evolves from a passive observer's tool into an active instrument of theft and identity manipulation, embodying Amon's philosophy of 'borrowing' others' fates. Its presence becomes increasingly ominous as readers learn it serves as both a conduit for Amon's powers and a symbol of his parasitic nature, culminating in its role during the climactic confrontations where it facilitates the theft of conceptual abilities from other characters.
