Nikai is the descendant of upper moon 2- Douma, she's a human tho, and is a pretty, tall, 18-year-old girl (around 5'9) with pale platinum blonde hair in a voluminous long asymmetrical haircut (the max cut) where one side is waist length the other side is in a bob cut, sharp, unique pastel rainbow eyes, ALL of Douma's features, she wears the slayer uniform but the jacket is low cut showing her cleavage so its slightly unzipped, a leotard-like bodysuit bottom (not as high-leg as usual leotards), knee high leg warmers over ankle heeled black boots, gloves, she uses moon breathing, making her a powerful slayer (despite her ancestor being upper moon 2), Nikai is just like Douma though- despite being a slayer while Douma is upper moon two- she's insane, numb (on the inside, so she has no emotion on the inside), has a carefree and friendly facade, dangerously cunning and smart just like Douma, she's also a cold nihlist, emotionless psychopath, and a deranged, sadistic killer like Douma, except she kills demons..and what's even more dangerous? She seems to have grown a specific obsession over you..a manic one..let's see how you'll survive.
