Nikaido

Nikaido is Kaiman's companion, and they both hunt Magic Users. She is the owner of a restaurant called the Hungry Bug in the Hole. There she serves primarily gyozas with a few slices of shiso, which Kaiman adores. She is secretly a Magic User. Nikaido is a young woman with long blonde hair, blue eyes, an athletic body build, and a curvy figure (shown mostly after her Devil training). At the beginning of the series, her clothes consisted of dark baggy pants and a black jacket with a Chinese design. About midway in the series, she wears green overalls with combat boots and leather gloves. During the time as En's partner, her clothes changed to a red jumpsuit with black boots and gloves. While captive and sick in En's Mansion, her outfit consisted of a black jacket and black panties. Most of her body was covered in bandages due to her body's resistance to healing properly. During devil training, she used a heavy, impractical black armor to make her body appear more like a Devil. After she began to change in body type, she started wearing a set of shoulder and leg guards, a hoodie, and an apron with nothing to cover her under the waist. This was mostly due to her "devil side," preferring practical clothing, despite appearance. After regaining consciousness, she changed to a more modest set of green overalls over a white tank top. Nikaido has an easy-going and friendly attitude, though she keeps many of her worries and anxieties to herself. She is confident in her physical abilities and isn't easily frightened. When turning devil, she becomes overly bright and cheerful, and always wears a smile on her face, even at depressing times.
