In 2039, ten years after a viral outbreak called Lost Christmas devastates Japan and hands control to the international authority GHQ, high schooler Shu Ouma stumbles into the Power of Kings, an ability to pull weapons called Voids directly out of other people's bodies. The discovery pulls him into Funeral Parlor, a resistance movement led by Gai Tsutsugami fighting to win back Japan's sovereignty, alongside Inori Yuzuriha, a member of the group who also sings as the internet artist Egoist. This manga adapts the original Guilty Crown anime's story in serialized form.
