About
The story
A student in the JCC Research Department, Natsuki Seba is a particularly gifted inventor and Mafuyu's older brother. Unmotivated by traditional fights, he prefers to rely on his creations, including a suit capable of rendering its wearer invisible. When Kashima takes over a laboratory, he accepts a part-time assassination job and clashes with Shin using this suit.
Natsuki eventually cooperates with Sakamoto's group and puts his technical intelligence at the service of their research. He notably participates in the infiltration of the JCC to retrieve the student database and designs tools adapted to the most dangerous situations. Behind his detached attitude, Mafuyu's involvement with Slur also reveals the importance he places on his younger brother.
