List of Infinite Ryvius Characters - Kozue Izumi

Kozue Izumi

Kozue Izumi (和泉こずえ, Izumi Kozue?); Voiced by: Sakura Tange (Japanese), Jocelyne Loewen (English)

A 16-year-old girl from the moon, Kozue expresses her emotions easily and with clarity as she is honest about them. She wears her hair in twin side pigtails, making her seem younger than she is. In the flight attendant program, which she joined mostly because her friends were also enrolled in it, Kozue becomes good friends with Aoi, and by extension, Kouji and Ikumi. An honest girl, Kozue talks to Yuki without fear, despite his reputation. Kozue has a crush on Ikumi, and only stayed for the Dive Break because he was. She also seems to be somewhat spoiled, and often flaunts her relationship with Ikumi.

Over time Kozue's spoiled behaviour led to several jealous girls, tired of Kozue's selfishness, to attack her. The result of this incident led to Ikumi Oze becoming unhinged. A secondary result was that Kozue requested to leave the dormitory she shared with Aoi and Reiko in favour of a private officer's room, a request that in the circumstances could hardly be refused. She spent most of the remainder of the Ryvius's voyage in that room, unwilling to leave or contact anyone except for Ikumi. Also, she wore her hair down for the last few episodes following her assault, as a testament to the childhood she lost and her newfound maturity; this also makes her resemble Ikumi's sister more. She seems supportive of Ikumi until the very end of the Ryvius's 1st voyage. She is also present on the second voyage, when she reconciles with Aoi, and her relationship with Ikumi is left open.
