人間に対して強い憧れを持ち、いつの日か人間になりたいと願う、妖怪人間の紅一点。
普段はアナベラという名で、アッパーサイドの名門校セントジョーゼフ・ハイスクールに通い、同級生たちとのスクールライフを楽しんでいるが、これは人間になれた際に不自然な行動をとらない様、予め人間社会に溶け込んでおこうという彼女なりの努力である。
妖怪人間の自分は、普通の人間と違う、ということにまっすぐに向き合っているため、人間に対する偏見も薄いが、そのせいで傷つくことも多い。
本来的には喜怒哀楽が分かりやすいタイプだが、無口なベム、皮肉屋のベロに囲まれているため、口数は多くない。
華麗な動きで、右腕に仕込んだムチを華麗に捌く。冷気を操る特殊能力を持つ。
The only female of the YOUKAI-NINGEN. She admires for a human being, and craves for becoming one herself.
She usually goes to a prestigious school “Cent Joseph high school” located in Upper town, hiding her true identity under the name “Annabella” and enjoys the school life with her classmates. For her, this is an effort to get along with human society when the time comes to her to become a human being.
Because she faces the fact that YOUKAI-NINGEN is different from other human being, she does not have a strong prejudice against humans, but is often hurt by that very fact.
She is by nature an expressive person, but because she is usually with silent BEM and BELO, she does not talk a lot.
She gracefully handles a whip which is hidden in her right arm. She also has a special ability to handle a freezing air.
