He became an angel in episode two. His exceptional willpower allowed him to retain consciousness for a very long time, which he used to exact revenge upon people who previously maltreated him. After he loses his consciousness completely and attacks Rin, she has to kill him by impaling him with a tree branch. Eipos expresses desire to obtain Shōgo's time spore but Rin instead gives it to Maeno, who eventually uses it to become an angel himself, saving Rin from Sayara. After Maeno is killed by Eipos, his time spore falls into the ocean and is lost.
