Shioji has an androgynous appearance, his height similar to an average junior high school student. He has light blue hair in a bobcut and wears a top hat sporting a feather. Shioji wears a custom made private school uniform and has two masked impurity servants by his side. As is common with Basara, Shioji has one golden eye and one mismatched with a dark sclera, a cracklike scar running from it to the other side of his face.
Shioji appears to have a cold demeanour as he has shown little regard to ending human lives and using reanimated bodies to achieve his own goals. He also speaks in the third person as a narrator in a story when thinking aloud or interacting with others.
Powers & Abilities
Shioji's main ability seems to be the power to animate,corrupt and control corpses, seeing as he killed scores of Exorcists to reanimate their dead bodies as his personal army to attack in mass.
- Gedo Meiru (外導冥褄 Gedō Meiru?, lit. External Conductor, Dark Rags): Shioji’s Impure Death Equip that seemingly allows him to manipulate and control lesser weaker Impurities than himself to fight and defend him,as seen during his battle against Tatara. 
- Gego Itto (外護一燈 Gego Ittō?, lit. External Defender, Single Light): Shioji's seemingly most powerful spell,where he enchants several gigantic Shinja class impurities to merge together to form one gigantic impurity monster to serve him. Shioju having used this spell using the leftover Impurities left over from Sakanashi's Army in an attempt to seize the weakened and injured Tenma Unomiya's Spell Powers. 
- Shioji shared the ability to control and manipulate the dead with the previous 8th Basara,Chikura.
