Ichiroubei Hiiragi  

Professor Hiiragi

Professor Hiiragi is a scientist who discovered how to access the Sixgate World and is Rokuna's father. He enlisted Mondo and her to safeguard him as he searches for objects that link its magic to humanity, in order to gain renown. Although his companions adhere more strictly to rules and ethics, Professor Hiiragi is highly fixated on finding these items.
