Ikuyo Suzuki

One of Taro's friends, a 17-year-old maid with thick glasses and often sporting a sly mischievous look. She is the head of the Technology Department, and specializes in mechanics and odd inventions, some of them blowing up or otherwise malfunctioning in rather hilarious ways. Rather oddly enough, she is also an otaku. In one episode rife with nods to other anime, she brings several other characters to the world-famous "Comic Market" ("Komiketto" for short in Japanese) in Tokyo with her self-made dōjinshi.
