Kouki (a Touhou LW original) refers to red lights in the sky, in other words, a low-latitude aurora. This is an apt temperament for Flandre, who has continued to destroy fate in order to end the Lost Word Incident. Flandre's temperament has been completely reconstructed. She cannot avoid her weakness to running water (Water Phase), but the lights of the night sky (Moon Essence & Star Essence) are her ally.

The ability of Flandre Scarlet, who has almost reached the end (a Touhou LW original). Flandre completely lost this ability due to a Lost Word. She is currently regaining it little by little, though not through restoring or replicating her old ability, but with a newly constructed original ability that formed a core to build upon. She has continued to travel across worlds to try and end the Lost Word Incident. Even now, there is still no clear definition of what Flandre's ability to destroy absolutely anything actually entails. However, one can assume that her ability lets her forcefully impose a destructive fate onto any target as long as she has the necessary energy and can grasp its "eye." It wouldn't make sense unless she had to pay some sort of price to activate this ability. And besides, if there weren't any restrictions, there would be no limits to her power, meaning she would never have lost it in the first place. There are still many more mysteries concerning her ability. In fact, the hypothesis listed here about what she is and isn't capable of could be completely wrong. As can be seen in the report about the falling meteor, there is some kind of connection between the abilities of Flandre and of her older sister, Remilia Scarlet. This Flandre's ability seems to have maintained this connection. Magical Megaton Mace: This is Flandre's favorite toy. It's also called Triple M or M3. The mace is a manifestation of Flandre's room which was essentially her entire world for 495 years. While it is a manifestation, you shouldn't mistake it as the physical room condensed into the form of a mace, even though it has its own mass and power. In this regard, it is the same as the items possessed by the rest of the Restored. It's theorized that concepts that cannot usually be seen or destroyed, such as memories and fate, acquire physical and magical mass at extremely high densities. The fact that these items possess a will of their own is thought to be a natural consequence of this, but that notion lacks a strong theoretical basis. It's like a dimension-transcending object that requires parallel worlds to function... but could such a thing truly exist?
