Senri & Rima

Shiki & Rima are both Models, They both share the same personality and are almost always seen together. Its not very clear how deep their relationship is as we never really seen them drink blood from one another as some of the other vampires, BUT they held hands!. but we do know that Rima does care for Him. We have seen Rima being Worried for Shiki and is wondering if he's okay
