Katsuo Iwashima

Katsuo is Saburo's young weapons expert and second in command of the compound security. Katsuo is a fiery young man, consumed with his job and his duty. He considers Shintaro a hopeless anachronism and covets Shintro's job as chief of the Arasaka Family compound security. Katsuo is, however, smart enough, however, to treat Shintaro with open respect and deference.

Katsuo is secretly in love with Hanako but he keeps his feelings hidden. He knows that if word of his emotions got out, he would be discharged by Saburo and possibly damaged by Shintaro.
