Akira Kazuraba

Akira Kazuraba (葛葉 晶) is Kota's sister who works as an office worker at a subsidiary of Yggdrasill. She is protective of Kota, but she still understands that he has his own desires in life.

History
Learning how the Inves Games were growing in popularity and the development of the planned municipality of Zawame City, Kota, unsure of his place in life, asked his sister what it meant to be an adult. Stating it as meaning to be able to look after yourself, Akira assured Kota that he was an adult as he was now paying his rent and buying his own food. Kota noted that looking after himself was all he could do, with his hands full with work, he had to drop everything he used to care about to do it. When Kota told his sister that he wanted to transform into someone strong enough to do everything, she explained to him that he wouldn't wake up one day and be a completely different person, saying that life wasn't that easy. She assured him, though, to just take things slow, and he would become the adult he wants to be.

After discovering the Sengoku Driver and transforming into Armored Rider Gaim, Kota was quick to show his sister his Armored Rider form, which fazed her only slightly. After a dinner of meat and potatoes, Kota's loud changes in the bedroom annoyed Akira downstairs, who told him to pipe down. This underwhelming reaction to his transformation was not what Kota expected, disappointing him.

When Kota came home with much more money than he made with his jobs, revealing that it was prize money from winning the Inves Games and that they would be able to live off it, Akira rejected his contribution to their monthly expenses. She was displeased with the way that Kota was "earning" money through the Inves Games because the money was won for playing a game that benefited only himself and his team, instead of being earned through the efforts of an honest job that benefits others.

Akira called Mai and Mitsuzane to talk to Kota, who had shut himself in his room, having lost his confidence after nearly being killed by a white Armored Rider and realizing the mortal danger of what was originally a harmless game.

While watching the news, she tell Kota that people are starting to have plants growing in their body as Akira wonders if the Beat Riders are the cause of the disease.
