Tsume

Tsume (ツメ, Tsume lit."Claw") is the second wolf to be introduced in the Wolf's Rain series. Rough and self-reliant, Tsume is a strong fighter who keeps his true feelings to himself. He only joins the others out of boredom and does not, initially, believe Paradise to exists. Though he frequently quarrels with Kiba over the course of their journey, he eventually comes to believe in Paradise as strongly as Kiba does.

Human-guise
When in human form, he is tall and relatively muscular, with cropped silver hair that he ties back in a small ponytail. He wears one stud earring in his right ear and two hoops in the left, one larger than the other. He wears a tight, black leather ensemble that exposes his belly, the sleeves partially ripped off.

True form
Tsume is a large grey wolf with gold eyes and a prominent, x-shaped scar on his chest. However, Toboe has noted that Tsume has scars all over his body.

Tsume is depicted as a "stereotypical, angry anime loner" who curses a lot, but is very confident, and at times arrogant, and keeps himself distant from his allies. Though he and Kiba continue to come into regular conflict, Tsume eventually comes to believe in their goal and becomes a loyal pack member. He has a short temper and an aggressive personality. He's standoffish and aggressive with an attack first and ask questions later mind set. He is not friendly to new wolves or humans or anyone really.

In the anime, it is shown that before he lived in Freeze City, Tsume had always been a lone wolf and preferred being on his own to travel the world. Eventually, he found himself befriending humans more than wolves before blending in with them.

In the OVA, it is shown that before moving to Freeze City, Tsume had lived in another location with a large pack of wolves. Lady Jaguara's wolf hunting troops attacked the pack, killing most of his family and friends. As Tsume attempted to flee from the battle, his pack's leader attacked him in retribution, giving him his trademark scar. After, he was cast out by his pack, leaving him to travel until he made it to Freeze City where his self-loathing over his actions caused him to refuse to befriend others.

"Even if Hell is what we're headed towards...You people may not have been able to find Paradise, but there's absolutely no doubt in my mind...That we will."
"Well, if worse comes to worse, we can always eat each other...We can start with the runt since he's gotten so weak. And of course, there's always little Porky over there..."
"You once asked how I got this scar. Well, members of my pack were being slaughtered! I should've have stayed and helped my friends, but I was a coward and ran away. The members of my pack who were still alive blocked my escape route. They gave me this scar as a reminder of my sin, and then banished me from the pack. I never trusted anybody again. I no longer wanted anything to do with friends...until I met you three."
“I don’t trust anyone, so no one trusts me.”
