National Security Bureau Section Zero

National Security Bureau Section Zero (国家安全局0課) is a branch of the Tokyo Metropolitan Police Department, secretly investigating Kamen Rider Wizard and the Phantoms while keeping the knowledge of them from the public. Masanori Kizaki is a member.

History
Kizaki was originally partnered to Katayama around the time of the Sabbath, learning of the Phantoms' existence while investigating mass disappearances. He promised his senior partner that he would protect his son Naoki when Katayama tried to stop the Phantom Gargoyle. Though he originally saw Haruto to be no different from the Phantoms, abducting Wajima to commission his services in creating a Wizard Ring, Kizaki became an ally when he saved Naoki and gave the Kamen Rider the Magic Stone that is later made into the Hurricane Dragon and Thunder Rings.

After Haruto and his friends encountered Kosuke Nitoh, who was revealed to be the ancient magician, Beast, Rinko asked if Kizaki had looked into it, only to find out that Section Zero didn't seem to know about this other magician yet.

Later, he sent Haruto and Rinko to investigate the missing hairdresser named Sora Takigawa, the Phantom Gremlin's human identity.

When he was about to search for a man named Fueki, he found out his true identity by combining the related incidents of the Phantoms and Magicians. However, he was kidnapped by someone. However, it is revealed to be the White Wizard himself who ambushed. Kizaki was later retrieved and left in a coma at hospital's ICU.

Kizaki was then awakened from his coma and gave Haruto the information about Fueki's plan and his address. After the final battle, he accepted Mayu Inamori into Section Zero at Rinko's recommendation.
