Rei's rinkaku kagune consisted of six tentacles that ended in long scythe like blades. They looked somewhat similar to spider legs but with less joints and flat scythe-like sharp ends. Shiki had taken the talented young man under his wing as his protégée and trained him into a very capable fighter and leader. Rei Suzuya had changed in appearance since Muri had captured and experimented on him. He was way less scrawny and had built up more of a lean, tall muscular physique. His body seemed to have reacted well to Shiki's serum and ghoulification procedure, it fully utilized the metamorphosis to heal all of Rei's past injuries, scars and handicaps. His hair had changed in color from white to black which he grew out and wore in a samurai bun to model after his mentor. The only trait he still had from before his transformation was his body stitches using red string. He even used the same type of string to tie his hair into a samurai bun. So far, Shiki felt Rei had proved himself by excelling in the trainings as someone loyal and capable of leading Shiki's personal army. The young man had taken on a more serious though still laidback attitude under Shiki's mentoring. He had the authoritative tone to demand respect from the other Artificial ghouls as well as the other natural ghoul members of Aogiri Tree.
