Noi

能井

Noi is apparently En's cousin. Her smoke heals nearly any injury, barring actual death. Shin is the person closest to Noi, as shown when he revived her from her reptile form.
She is taller and stockier than Shin. Fujita is surprised to find out she is female the first time he sees her without her mask. Noi has pale blonde hair and red eyes, which suggests she might be an albino. Her hair is mid-length, and she has several ear piercings.
Noi's mask is very detailed, though dark blue and apparently vinyl-like. It is somewhat similar to Shin's mask, but more form-fitting and featuring a zipper.
