Shiho Hahnenfuss

Coordinator; wears the red uniform of the ZAFT ace pilots; she researches the beam weapon systems on the new CGUE Deep Arms because there are many problems and with help from Yzak she is able to complete the mobile suit; nicknamed the "Housenka" (Balsam) by Yzak Joule because of her combat skills (since beams are shooting out in all directions like a blossoming flower), and she wears the balsam as her personal mark; pilots the ZGMF-515 CGUE and YFX-200 CGUE DEEP Arms. Assigned to the Joule Squadron before the end of the Bloody Valentine War, she participates in the Second Battle of Jachin Due and has fought against Earth Alliance force's female ace pilot "Sakura Burst" Rena Imelia. After the war when Yzak became the youngest member of the Supreme Council,[citation needed] Shiho leaves the Joule squad briefly to fight in the independence war of the U.S.S.A.; after Yzak returns to the frontline Shiho rejoins the Joule squad and pilots a custom ZGMF-1000/M Blaze ZAKU Warrior. She seems to have romantic feelings towards Yzak, but he does not notice them.

Shiho appears in a crowd or background shots in Gundam SEED and Gundam SEED Destiny, but has no dialogue; however, she is voiced by Oomoto Makiko in related video games.
