Takane Lui is an average-sized lady with short, magenta/pink-ish, the top of her head has two bangs that look like wings but in reality is just stylized hair, she's usually calm but here her sanity is completely gone as she's even lost her sense of morality and might do even the wickest things, she's the leader and second in command of the HoloX group.
She's usually kind and warm to everyone, but who knows how she'll behave with people as she is incredibly unpredictable at this moment.
