Kimi is a Holistic Esper that produces Supermassive Black Holes across the universe subconsciously and took one of Touma’s Dragon things into her own right arm. The Dragon constantly absorbs the energy jet emission of one of her Black Holes which she uses to power her attacks. Frillsand’s an artificial ghost that kills while she’s in your vision through some act of death. If she says death by drowning, you drown from nothing, if she says death by being sliced in two or being run over, your sliced in two or turned into mince meat out of thin air
