Keiji Fujiwara was a Japanese actor and voice actor.

Even though he was born in Tokyo, he spent the majority of his childhood in Iwate Prefecture. In high school, he handled vocals in a band he formed with his friend Kotaro Furuichi, future guitarist of rock band The Collectors.

At around 18 years of age, he moved back to Tokyo on his own and joined the Bungakuza acting school. He spent the 1980s performing in several theater troupes while working odd jobs. Fujiwara was introduced to his first voice acting agency, Ken Production, in the early 1990s. The first TV anime in which he appeared as a regular was [Yokoyama Mitsuteru Sangokushi](https://anilist.co/anime/970/), but his breakout role was [Hiroshi Nohara](https://anilist.co/character/33466/) in [Crayon Shin-chan](https://anilist.co/anime/966/).

In November 2006, he left Ken Production and founded his own agency, Air Agency. Aside from talent management, the company went on to release original drama and situation CDs through its child company Air Label, as well as produce live events. In 2010, Fujiwara made his own sound directorial debut in Kakkokawaii Sengen.

In August 2016, Air Agency announced that he was going on hiatus in order to undergo medical treatment for a then-unspecified illness. He officially resumed work in June 2017. On April 16, 2020, Air Agency announced that Fujiwara had passed away due to cancer on April 12, 2020.

Kotaro is a robotics and technology genius who has become the object of an evil group's attention. They want Kotaro to help them build their Machine Empire and beef up their artificially intelligent creations, the B'ts (pronounced "beats"). Once the Empire captures Kotaro, he may have no choice but to work for them, unless his kid brother Teppei can somehow rescue him. But after a powerful B't and its master attack Teppei, it appears Kotaro's last hope is lost. However, Teppei's spilled blood awakens a legendary B't (these evil creatures bond with blood), so Teppei now has one of the most deadly, sentient creatures-the B't X-at his command. Still, the brothers are up against an army from the Machine Empire, and the odds are against them. Even if they survive, B't X isn't keen on going up against another creature from the Machine Empire.
