Smith was a French spaniel mix with black-and-white fur.
He had brown eyes and yellow collar. He lost his collar somewhere between Ginga Nagareboshi Gin and Ginga Densetsu Weed.
His long ears seemed oddly shorter in Ginga Densetsu Weed because of a change in art style. His right front leg had been amputated.
Smith was often comical, sarcastic and jokes around. He was good friends with Gin, though he underestimated him at first due to his age.
He often bullied Cross a bit and she always had something to say back. Smith always had small comical quarrels with Moss as well. They didn't really dislike each other, though, and they were friends. Actually, Smith was in love with Cross, even though he knew that she loves Ben.
According to a joking Cross, Smith was a womanizer. In the manga, he once said strictly that he is not into males. However, he later hugs and licks Chutora, showing that he has no problem with being physically closer to other males.
Smith may seem slightly cowardly and timid at the times, but he had a very strong side. He showed fear and dislike of wolves at first, more than the other dogs, but eventually accepted them.
During the battle against Akakabuto's bears, Smith showed his very brave and serious side and was ready to die fighting. He hated it when he could not carry on in the battle after being injured.
In Ginga Densetsu Weed, Smith is older and seems much more serious. However, it's revealed that before the disappearance of Sakura, he was joking and laid-back just like when he was younger. It's likely that the failure of protecting Sakura and loss of his leg made him change a bit.
As an older dog, he felt responsible of younger dogs and wanted to teach them manners and protect them. Sometimes they may annoy him a bit and he doesn't always believe them.
Ginga Nagareboshi Gin
Smith was Riki's third platoon leader. Gin discovers the wild dog pack one night and decides to join them in defeating Akakabuto. Along their journey, they meet the three kai brothers and Moss, in which Smith and Gin learn that Sniper and Hyena are traitors.
This is why Smith was quite close to Gin, since Gin saved him from falling down the large waterfall as Sniper and Hyena chased them to keep them from disposing their devilish plan. Though Smith told Gin to save himself, Gin refused to let go of Smith and saved them both.
Smith and the others continued finding other dogs like Akame and helps defeat the Koga clan, and Benizakura, the strongest dog in the world. They returned one night before the final battle and prepared to fight.
Being wounded, Smith was left with other wounded and Cross (and her puppies). He revealed his secret feelings for her, believing that a bear was coming and was ready to die to protect her.
However, the "bear" turns out to be the hunter Takeda Gohee.
Smith led him to the battlefield where Akakabuto was, hoping that the man will shoot the bear. Smith survives the final battle and stays in eduu mountains with his friends.
When the wolves caused conflict, he was the only soldier to stay in Futago Pass to protect it. He met Fuuga the wolf and was scared at first though the wolf is actually an ally and meant no harm.
Smith is later terrified to find out that Gin had allied with wolves. He stayed in Ou while most other soldiers went to fight Gaia's soldiers.
Later, he was again terrified to find out that a few wolves have joined Ou's forces. Moss scolded at him and he eventually accepted the wolves as a species and as his comrades.
Ginga Densetsu Weed
A year and a half ago Akame, Gin, John and Tesshin along with Gin's wife, Sakura, went on a journey to give their consolations to the families who lost their loved ones in the war against Akakabuto. Meanwhile, Smith and the other officers stayed at Futago Pass, for the case if something happens so they can be used as a messenger. But during the journey Sakura become week because of pregnancy. On Gin's request, Tesshin went with her back to Futago Pass, so she can give birth to healthy children. Gin promised her to come back after a year. Since that Smith got the mission to watch over her so nothing can happen to her and her children.
After a month has passed, a Lady named Lucy couldn't resist her jealousy toward Sakura anymore, because she always was happy and had a good life, not like Lucy who lost her husband and was depressed since then. Never speaking to anyone, Lucy suspiciously started talking to Sakura. But Smith, who should take this as a warning, just ignored it and didn't saw this as a bad sign, although Tony and the others were very skeptical. On that day He and the other three officiers went hunting and left the two women alone. Lucy used this moment to get rid of her and her constant happiness. She told her the lie that Gin was serious injured and that she had to go to him. Sakura fell for it and listened to what she said. Then Lucy put her in a truck and didn't even knew where it headed.
Later, when Smith and the others arrived, they couldn't find the women and started to panically search for them. But they only found Lucy crying and begging to be killed after she screamed out her jealeosy.
When Akame, Gin, John and Tesshin arrived at Hiroshima to search the family of Mitsunaga, suddenly Smith approached. He searched for Tesshin to tell him that he lost Sakura and couldn't find her. Smith begged him to not tell this their boss and he promised to find her even if his own life depends on it. He then went to search for her.
BSomeday he meets GB, who was going to be run over by a truck. But Smith saved him by pushing him away and got hit alone. He was instantly brought to a hospital and got his right foreleg amputated and was on the border between life and death. He was forced to stay at the hospital for two months, though he often tried to escape, despite the pain he had.
Smith meets Weed when he was fighting the The Guard Dog, who then hid from Smith once he sensed the elder dog's fierce spirit. Smith later went inside Gajō to protect Weed from Kaibutsu. He tricked P4 into collapsing the cave by jumping on his back, which made P4 bang Smith's back on the rock walls, causing him to be crushed.
They both were assumed to have died, Kaibutsu survived. This was where Smith's life ended.
