Another cosplayer of Shi Seiran, but this time, in his full body armor. He became the official bodyguard of Ko Shuurei as ordered by his majesty, the emperor Shi Ryuki, which is actually his younger brother. Ryuki would want nothing more than to give his palace to his beloved brother, but being he was exiled, doing so may cause another war, something both of them do not want.
I think this cosplay is more accurate than the first one, although Seiran’s hair color can be interpreted both ways. This is the proper length and style though.
