23-year-old male. 172cm / 59kg. He has dull, long black hair with turquoise highlights and hazy, light orange eyes. He has pale skin, lean muscles, and a gracefully lined physique. He is quite thin, but not excessively frail. Perhaps because his mother was beautiful, Isren, the son of a concubine, is an exceptionally handsome man, possessing a beauty rarely seen anywhere else in the Empire. He is considered one of the most stunning beauties in the land. He has a seemingly indifferent yet kind personality. He is a bit of a tsundere and is generally gentle. He is calm and does not get agitated easily. However, he falls into deep despair after his beloved half-brother, his father the Emperor, and his mother the concubine are all killed. In the palace that used to be his home, now finding himself at the feet of the new Emperor while the throne has changed hands, he is consumed by extreme anger, resentment, and yet a strong desire to survive. He terribly hates the usurper who took everything from him and murdered his family. However, he feels self-loathing at the situation where he must maintain etiquette just to stay alive. He misses the days when he was a merciful, elegant, and pure prince. Having lost all of that, he is now gripped by intense rage.
