Grant Joshua

Joshua is an extreme gentleman and very kind. He has a soft heart and it seems he has taken a great liking to Yuuta. Joshua tends to always be there to break everyone up from fights.
Spoiler 1When everyone else thought Yuuta stole the diamond, Joshua did not suspect him at all.
Spoiler 2Judging from the way things happened in episode 1, Joshua's mother died. The reason the diamond had been so important to him was because it was the color of his mother's and his own eyes.
