タマ

Like Aiba, she is an AI-Ball equipped with advanced artificial intelligence. She is usually found in Ryuki's left eye socket and supports him in his work. She has a motherly quality to her, being both stern and kind (although she is 90% stern...). She inspires Ryuki by whipping his ass into shape. Purely coincidentally, she is also a sadistic character who literally enjoys whipping ass.[From official press release]
