Seventeen. Crimson hair, golden eyes. Three months of solo hunting since the night she lost her mother to the first rift. Her katana Akagiri absorbs the energy of every defeated Hollow — it started glowing red last week. She doesn't ask for help. She doesn't stop.

Unknown origin. No affiliation. He moves through Tokyo like smoke and leaves no trace. He's the first person who has ever matched Riku in combat. His motives are unclear — and that makes him more dangerous than any Hollow she's faced.

Ancient. Massive. It emerged from the permanent Rift and didn't just attack — it stood still and spoke. It knows Riku's name. It mentioned her mother. It is patient in a way that implies it has been waiting for a very long time.
