Nagoya, Chiaki

名古屋稚空

Chiaki is a new student who resides in the same apartment complex as Maron (specifically in the neighboring unit) and shares her class with Maron and Miyako. He ran away from home to pursue something he wanted to do. Like Maron, Chiaki possesses an alter ego known as Kaitou Sinbad. He also has the ability to seal demons using pins, similar to Jeanne. Although he initially appeared to oppose Maron, he did so for a specific reason. He was also aware of Maron's true identity. In the manga, he used daggers instead of pins to seal demons. Chiaki is a "ladies man" or "womanizer" who constantly attempts to seduce Maron. At first, she could not stand him or his habit of always trying to protect her. Initially, he claimed he was merely trying to get closer, but later stated that he wants to protect her forever.
