Renzo Kishua

A Dark Knight/Gunbreaker that bumped into Kazuko one day. The two seemed to get along very well, as they've had some similar experiences (albeit, Renzo doesn't have an illness like Kazuko does). Kazuko is internally considering asking him to help teach her a bit more. He's since visited her a few times, helping her through a dizzy spell and taking her to the Starlight festival. It was on the way back from that that he unintentionally aided her in finding out she had The Echo. Later, when The Luna's were unavailable, he pulled some strings to get her a place to stay and receive care, and in addition, convinced Eitor to continue care, as well as intends to provide her with living quarters and (additional) steady income.
