Rigel is a black Akita Inu/Kishu Inu mix with blue eyes.
His color is fairly unusual, since none of his known ancestors are black.
Much like Orion, Rigel has a foul mouth, and he usually yells at his sister Bellatrix. He seems to have calmed down a bit after spending time with Kurohabaki Terumune.
He has a tendency to be hasty when wanting to fight his enemies even though he's outnumbered.
Also like Orion, due to his age Rigel can let fits of rage or sadness control him.
Just like his family Rigel too also fights for his comrades like when he was trying to protect Sasuke from the bears. Sasuke views Rigel's kindness, courage and bravery similar as to his father Weed.
His willingness and determination to protect Sasuke during the battle against Monsoon's Kin comes from the regret that he couldn't do anything to protect his previous mentor or help Masashige.
Despite his brothers constant arguing he understands them both.
Also like Weed and his brother Sirius he views all life as important as in he won't sacrifice one life for another.
Like Orion, Rigel is also beginning understand the limitations of the Ohu Army knowing that they need more than just their fangs to defeat Monsoon.

Ginga: The Last Wars
Rigel is away with his brothers, training at the Akame Mountains and has been so for 6 months. Sasuke arrives at the foot of the mountains and is greeted by Rigel and Sirius who take him to see Orion.
After the dogs have been reacquainted, they are informed of the situation and agree to gather help from their friends across Japan. Rigel and Sirius travel together to fetch reinforcements when they come across Unsai and his group. Unsai sends Kawasemi with them as he takes a different route. Eventually, Rigel and Sirius come across the gorge that was once leaped over by their father and grandfather. The two brothers make it over with ease, and assist Kawasemi in climbing back up after he slips. The three dogs then continue their journey.
Sometime later, a flood causes a wounded Ken to be washed into a river and the Ou army go to the location to find and save him. They each keep a watchful eye on the raging river, as Kawasemi dives in to find him.
When Sasuke begins to panic and says he doesn't want to die, Rigel take him away and tell him that he's taking him away from the battle for a bit. He tell him not to move and if he stay still, they won't attack him. Rigel return to the battle again.
Seeing that the bear has injured his mentor Rigel tells Sasuke that he's going to cut one of Monsoon's Kin using Ningatō. He tells Kyōshirō and Rocket to kill him and don't let him get up. Rigel tells Sasuke how could he be that rash and he can't die. Sasuke tells him go on and don't worry about him but he tells Sasuke that he'll be okay and not to move from he put him
anywhere. He says to him that he's got nothing to worry about and will protect him. Sasuke thanks him and tell him that makes him happy but still tells him to go and leave him here. Sasuke tells him that his friend is going come to get him. He ask Sasuke what are he saying and hold on. He tells him not to give up.
After the bears are gone he sees that Daisuke has come to help knowing that Sasuke and their injured comrades will be okay. Rigel goes with his brother Sirius to greet and thank him.
Rigel leaves with Sirius and Zion and locates Bob and hears his brother ask Bob for his cooperation and they head in the opposite direction away from Akame's group.
After getting Bob to cooperate Rigel follows Sirius and Zion in the search for Monsoon as they reach the edge of the woods. They come across Akame's group, even though he listens to Sirius's story of Monsoon's hatred for the Ohu Army, he continues to watch his older brothers argue even hearing Orion say words that left him speechless and then fight until it was cut short by Andy.
During the fight among his brothers, Rigel wished to say something but was stopped by Andy telling him that he doesn't have to say anything about how his brothers are acting. When Bob tries to make his escape he gets pinned by Bon but Rigel says for Bon to get off him and that he didn't become the bear's subordinate by choice. He and the others noticed that Akame has collapsed from exhaustion and had to pass the sickle, when Sirius tried to take the weapon Rigel tackled him out of the way thinking he was going to run away with it. But Sirius told Rigel not to get in the way and much more shock he heard Orion disown Sirius as his brother.
Rigel watches the fight between his older brothers comes to a boil, he begs for Orion not to attack Sirius but Rigel rushes in between them stopping Orion. He admits to his brother that he has the same opinions as him but tells his brother if he dares to attack Sirius with the sickle he'll protect him. Then, Orion points out the bears are only interested in eating them and Rigel gets asked is he just like Sirius and if so Orion won't go easy on him either.
He says that he couldn't think of living those bears after what they have done but Rigel also understood that Orion can't hurt Sirius just for thinking differently. Rigel asks Orion to stop pointing the weapon at Sirius. Rigel along with others watches Orion throw the sickle and it hits Sirius in the head. Then, hears the rest of the army coming and sees that they have brought humans and now he agrees that they have the power to beat them. Rigel watches Sirius trying to talk to Zion to convince the bears to run but Zion says those bears are not like the ones he knows.
Rigel watches Sirius climb up to the top of Futago Pass, trying to talk to the bears when his brother sees that Zion isn't coming. He along with Orion watches Sirius shed tears in his eyes, then with everyone's combined efforts the rest of Monsoon's Kin is defeated. After that Rigel and his brothers greeted by Daisuke again and he isn't surprised that Rigel still remembers him as they are defeated the dogs howl in victory as Rigel gets petted by Daisuke. But he and Daisuke turn their attention to Sirius saying to Orion to quit getting everyone rattled up and that the battle is over. Rigel and Daisuke continue to watch the two brothers argue until Akame stops them.
Rigel watches Daisuke and Hidetoshi revive Akame but needs treatment badly and takes him away. He along with the others watch as Akame and Izou are taken away hoping they get well soon. He sees Sirius and Zion going after to Monsoon to talk to him, he is told by Orion to stop his brother but he refuses by saying that Sirius is different from then personality wise and growing up. Sirius will follow what he believes in no matter what and he hears Orion call Sirius nothing but a bleeding heart.
Some time later Rigel watches from a nearby hillside with his brother Orion and their comrades as Daisuke and the people of the village bury their fallen allies and pays their respects. Daisuke comes with food for them as a reward Rigel thinks that it's a good idea that everyone should eat and those that are injured should eat first with Orion agreeing.
After that he sees the Pet Dog Squad leave and Orion thanks them for their help and wishes them a safe journey home. The Squad tells Rigel they'll always be on the side of the Ohu Army with the black akita seeing them as thoughtful too. He begins to see that his brother is maturing along with him, then he hears about his brother's promise to Akame about staying out of anymore fights until everyone has healed.
As the days pass by he and Orion meet with Daisuke as he comes to treat the dogs that couldn't be housed. Then, the two are brought by Daisuke to see their father Weed in the barn, making a good recovery and happy to see him. They tell them that Sirius is fine and that he has nothing to worry about.
During the conversation Rigel asks Weed about their grandfather and Akame; he informs the pups that Akame is alive; their grandfather is at Daisuke's house. Then, their attention is turned to Akame saying that he can't die until the pups have grown into full fledged adults.
Rigel already believes that they are adults but Akame says they have grown in body but not in the mind. And Rigel informs Akame that Sirius has taken Zion with him to go after Monsoon, Orion also comments on Sirius naivety and that he doesn't care anymore; Sirius has even surprised everyone. However, their attention is now turned to Unsai saying he can't die not before they deal with Monsoon, Orion says they can't use him in his condition and leave everything to them, but Unsai informs them that they have to stop Sirius before he makes a terrible mistake to which Orion and Rigel can agree too. Then, Daisuke takes them to his house to see their grandfather Gin; they are introduced to Daisuke's father and they start to pick up their granddad's scent and rush inside Daisuke's house and they are glad to see him alive. Orion asks their grandfather if he can see again to which he can.
Rigel hears Orion tell their grandfather everything that happened including that Sirius went after Monsoon with their cousin Zion, that they should give up their revenge and become friends but Orion still thinks that Sirius doesn't know what he's talking about. But most importantly that Orion stayed because he promised Akame that they wouldn't go after Monsoon until everyone's healed and since Akame nor Unsai couldn't lead Orion had to take over and that as a leader he must act responsibly.
The black akita also hears Orion tell Gin that Sirius's kindness doesn't make any sense no matter how bad an enemy is, he'll always believe they'll have a conscience and believes at this rate he'll be killed and Rigel agrees to that too. He asks their grandfather what should they do but Gin says he'll handle this and hears from Daisuke that once everyone is healed they could go back home and seeing that their friends need them Daisuke offers to take them home.
Next, they notice their grandfather trying to stand up and Rigel tells him that his wounds will open up and shouldn't stand in his condition but once he's up. Rigel left with Orion and their grandfather to stop Sirius and find their comrades following the path Cross took and come across Tesshin surprised to hear him say words of despair until the Koga loses conscious. Seeing that Tesshin needs help Rigel rushes back to Daisuke's house and leads their godfather and Daisuke's father to Tesshin but Orion tells them it's already too late.
Then, he sees Daisuke carry Tesshin away for treatment and holds onto hope that Tesshin has a chance to live and reunited with Ken, Cross, Maru and Sunny. While walking back to the others Gin informs the group of Hiro, Lydia, Kenshin, his group and others passing. They group together and sleep the night away until Rigel is a woken by Orion and his friends; he asks them where are they going and Andy says they're going to the bathroom and goes back to sleep.
He is startled by his grandpa waking up from a nightmare then, Rigel discovers that the Kamakiri brothers and his brother Orion and his friends are gone. Figuring out where they went the black akita follows Rocket who tells him to go back but he refuses and comes across Orion and Bob. He asks is brother where did everyone and all Orion says is who's this everyone you talking about, not wanting to play games Rigel quickly realizes that everyone hasn't come back. Begins to asks if Orion told them to go but the red akita says he didn't however; Rigel asks his brother why didn't he stop them not sure what they can do with their small numbers.
Rigel chews Orion out for being extremely arrogant and having no consideration for others and leaves to follow Rocket.
He watches Rocket continue to convince Akakama and the others to turn back saying that it was Gin's orders but the irish wolfhound says that it has to be a lie that Lord Gin would turn his back on his own grandson. And that he should be the one to bring him back, he hears Akakama say that he is resigning himself from the army; watches the others leave after Sirius. So Rigel says that they should report whatever happens after this by saying that he wasn't able to keep up but when Rocket refuses. He thinks that Akakama scared him with Rocket chasing after him.
Rigel and Rocket continue to follow Gennai and the others until Rocket collapses from his injury but Gennai tells them that this isn't the time for resting. He stands up to defend the borozi understanding what he been through this couldn't be help. When he hears Rocket say that they should go on without him and that Sirius's life was more important than his own the black akita was astonished saying that his life was just as important as his brother's.
Then, he hears Gennai say that they are so disorderly because they don't have a leader when the great pyrenees asks who will step up but Rigel and the others refuse to answer so Gennai takes over. While the others go on ahead Rigel looks after Rocket.
Once Rocket is feeling better Rigel and him continue to follow the path of their friends hoping no one did anything reckless. Then, he and Rocket come across the forest watchmen and Bell asking her if she'd seen their friends but they hear a noise and discover to see Gennai being thrown by Monsoon. He sees his brother right in the bear's striking range until Gennai pushes him out of the way. After Sirius is knocked out by Monsoon, Rigel watches Akakama hastily attack the bear.
Rigel is relieved that Akakama has survived but after what has just happened he still hears Sirius tell everyone that he continue his quest with Monsoon.
Rigel hears from his brother that his purpose was to talk not to fight. With Zion still following him Rigel watches Sirius leave wanting to have a chance. He watches Gennai attack Sirius in a fit of rage for his attitude, then they all hear a cry help only to discover that it's one of the watchmen's dogs with his front paws cut off. Coming to a realization Rigel understands that only the humans could bring Monsoon down seeing that their power wasn't enough with Akakama agreeing. Also understand that the humans don't know anything about Monsoon yet; Rigel and the others begin to hear the watchmen's dogs owner's whistle and takes the fallen hunting dog back to their owners.
After Gennai leaves Bell with an important Rigel follows him as they track a helicopter hoping to lead the humans to Monsoon, until night fall and they begin to rest. They hear a scream and begin to suspect it was Sirius until the pyrenees calms them down, Rigel and the Kamakiri brothers come to check on his brother only to get attacked by Sirius who was angry at them that they came back and Monsoon starting to get angry.
After the harsh scolding Rigel gets from his older brother and leaves with his friends but too far away and quickly meets up with Sirius, Zion and the cub. After Sirius apologizes to the point where Rigel was shedding tears he couldn't understand why his brother wanted to reason with Monsoon after what he did. But after hearing his brother's reasons he finally realizes he couldn't convince him the trio leaves.
When Rigel and the others return to Gennai's group his leader sees that they were unable to convince him. He sees Sirius and Zion return to the group with the bear cub surprised that the cub is still with them, he gets asked by Sirius to take Chibi back to Ohu with them and after Gennai's bad choice of words Rigel blocks Sirius from attacking Gennai. Surprised that Chibi started to speak dog language and hearing that Sirius has big hopes for the young cub Rigel agrees on taking Chibi to their home with Rocket escorting them.
