Disaster strikes and one of the girls falls ill with a fatal disease. That girl’s name was Tanama Yuri, who, Rie be forgiven, looked exactly, and I mean, exactly like Mari. Despite their promise, well Yuri’s one-sided promise because let’s be honest, in fantasy stories like this, if two people loved each other as much as these two did, then if one were to die really, it ‘s wishful thinking to think that the survivor would go on and if they did live, that they would have a happy life. So of course even as Yuri begged Rie to live on after she is gone (due to her illness), Rie soon followed and it is assumed that she committed suicide. But what is made clear is Rie and Yuri’s feelings towards each other and with how long Rie has been waiting to be re-united with Yuri, it is no wonder that when she sees Mari, a person that to Rie is the one and only Yuri she loves more than anything in this world, she would of course kiss her.
