I thought it was Saji this entire time and it doesn't help that despite Issei and him being friends, he calls him Saji like it's his first name. I also though Genshirou sounds more like a last name. I asked this because I found out the names of his yonger siblings and noticed they both have Saji in their names.

Saji's sister is called Kasui/Kouho Saji I believe 匙 華穂 His brother is called Gohan/Gosei Saji I believe 匙 元悟
