Blitz's Links
Blitz actually treats Haru like a brother, even though they are only close friends. They have known each other since they were cubs, and has gained a strong connection with him (Even though they are close, he still finds it hard to tell how Haru is feeling).
Pretty much treats Blitz like a sibling, but sometimes their relationship can be one-sided since most of the time he has to be the one to "control" Blitz and his actions. Somewhat has a soft-spot for him even though he's known to become a hassle to deal with. Haru still cares for his well-being though
