Seimei Aoyagi

Seimei Aoyagi (青柳清明 Aoyagi Seimei) is the older brother of Ritsuka Aoyagi. He was born on the 14th of November, and his name comes from the lunar day “Seimei”. When he was seventeen, he was found murdered in Ritsuka’s classroom at school, although he could only be identified by his dental records as he had been set on fire. Later in the series we learn Seimei faked his death, but the person who died in his place has not been revealed.
