Hina Izumi
Hina Izumi (泉 比奈, Izumi Hina?) is Shingo's sister, who for some reason has superhuman strength, which she is a bit embarrassed about. She began working at the Cous Coussier restaurant as the Greeed awaken, worried for her brother's well being when she eventually learns of the incident he was in. To prevent her from worrying, Eiji sends her a text message using Shingo's cell phone stating Shingo is on an undercover mission and won't be home for a long time. Eiji later tells her the truth, while promising to save her brother. Eventually, realizing his reason of looking after Ankh, Hina convinces Eiji to work at the Cous Coussier so she can care for her brother's body. She often uses her super strength to keep Ankh in line if he begins to treat her brother's body poorly or when he does something she does not agree with. Ankh does not like her and the two often argue, with only Hina's bizarre strength allowing her to win arguments. Hina eventually comes to realize she has been relying on Eiji's need to help to an unhealthy degree, and is taking steps to ensure Eiji does not blindly sacrifice himself for other people's sakes. After much contemplation, Hina also realizes she has come to care for Ankh, and wants both Ankh and Eiji, as well as her brother, to make it out of the Medal conflict alive. During the events of Super Hero Taisen, after Eiji was seemingly killed, Hina joined forces with Daiki Kaito, and the Gokaigers' Joe and Don to solve the reason while Tsukasa Kadoya and Captain Marvelous are attacking each other.
Hina Izumi is portrayed by Riho Takada (高田 里穂, Takada Riho?).
