柱谷 小五郎 - Japanese

Kogorou was the one person that Ryouta trusted enough to tell him about the witches and what had transpired in the past few months. It was Ryouta's hope that Kogorou would be able to figure out what was inside DR623G or as otherwise called, the death suppressant. He was also supposed to figure out what was inside the cylinder that Ryouta gave him.
