One of Ayanami's close subordinates. On Hyuuga's part, he doesn't see Ayanami as his senior, but more like a friend or someone he likes. Hyuuga shows a happy face most of the time and is very rarely not seen smiling. He is also almost never seen without a lollipop (or candy apple) in his mouth and is always wearing dark sunglasses. He is always joking, being silly and is seldom serious, one example is that in manga chapter 8 he takes a lollipop he is eating out of his own mouth and offers it to Anayami.
