Hallow is a confident, loyal and dedicated individual. Hallow's also extremely courageous to the point of being fearless as he was his own willing to go on a suicide mission. However, despite it being one of his greatest strengths, Hallow's courage has also proven to be his biggest weakness as well. Whenever his sense of justice is overcome or a mission fails, it causes Hallow to lose hope and become so terrified he's unable to fight. He is 16 years old and Zaybi is his older brother.
