Design

Walter has short, spiky black hair, slightly tanned skin and light colored eyes. He wields the Gauntlet COMP that all samurai use and wears the default samurai uniform, although he wears the top for it open, showing off his chest. He wears a blue kerchief around his neck. Although hard to see, he has piercings in his ears: a ring and two studs in his right ear, and three rings and a stud in his left ear.

In the DEMONIC GENE manga, he is seen in a couple different outfits. The first is a dark shirt and dark pants, which he was forced into after being arrested. Once he reaches Tokyo, he takes a new set of clothes from a corpse: a black leather jacket, black jeans and combat boots.

Personality

Walter is a rash young man who speaks bluntly, but despite his demeanor he does have a caring heart and believes in doing what's best. He concludes that the nature of a Samurai's duty is a perfect match with his personality.

Since he comes from the family of Casualries like Flynn, he feels sympathy towards those who are looked down on by the noble Luxurors.

Due to his boisterous nature, there is some friction between him and fellow rookie Jonathan. Though limited to minor scuffles at first, events throughout the story make this feud go from a simple conflict to a climactic clash of beliefs.

Profile

Walter is a newly recruited samurai who exterminates demons. His main motivation for becoming a samurai is for the adventure, as well as to escape life of being a mere fisherman. Walter immediately warms up to Flynn over supposedly meeting him in a dream he had not too long ago, as well as the fact that they are both Casularies in an order largely made up of Luxurors.

He dislikes Navarre and gets worked up when he looks down on him. Leading him to take part in the challenge Navarre makes about who can complete the three Challenge Quests first. After Flynn wins, Walter is informed by a samurai that Navarre had gone missing, and went to help him. However, he was ambushed by the Hooded man and was injured as a result. He meets up with the others after they defeat the Horde summoned by the Hooded man and is angered when he learns what is really going on from Jonathan, wanting to pay back Navarre for what he did and accompanies Flynn. After witnessing Navarre's breakdown once he's saved from Alraune, Walter decides not to verbally insult him for his actions. Jonathan implores him to not consider Navarre to be representative of all Luxurors; Walter concedes that he can see that Navarre is a "special" case.

The next day on their ticket of leave, he decides to take up Jonathan's offer to go to a well-known bakery after learning what Jonathan's real motives are, and expresses annoyance that Isabeau declined to join them. He is shown to be disinterested in the Baker's love of Literature that began circulating among the Casualries, instead impatiently asking him to hurry their order. At Lake Mikado, he offers Flynn's friend Issachar a chance to join their picnic, but he declined and returns home. Walter decides to take a nap there after eating breakfast, and the three go their separate ways.

Later that night he decides to spy on Isabeau and wakes up Flynn and Jonathan to join him. He wants to see what she's up to and make her embarrassed, and get her "prim iron mask" to drop. Not being quiet enough, she got the jump on them instead. Isabeau explains she went to the roof to get better lighting to read the manga she came across, and expresses her earnest fascination with its story. During the conversation, she notices the western sky had a red glow. Seeing the fire, Walter realizes it is from Kiccigiorgi and the four of them leave the rooftop.

At Kiccigiorgi Forest, they encounter Issachar who transforms into a demon and attacks. If Flynn elects to mercy kill him, Walter reassures that he did the right thing. Thereafter they find the Black Samurai, a mysterious woman clad in ebon armor. Walter informs her they will be taking her into custody, but she summons the Lilim Horde and escapes. The demon girls release a bewitching aura that renders Walter, Jonathan, and Flynn unconscious, leaving Isabeau to fend them off alone.

When the Monastery tasks the Samurai with pursuing the Black Samurai into the land of the Unclean Ones, Isabeau shares a rumor she heard from the monks: that Abbot Hugo is using the Black Samurai's escape as an excuse to have Samurai collect more mystic relics from the underworld, to which Walter expresses disgust. After going to the floor below the Hall of the Minotaur, Walter asks if they can rest as his demons are bugging him about being healed. Upon finding a curious mystic relic in the excavation chambers that Burroughs identifies as a "gun," he suggests they take them along to be used.

Arriving in Tokyo, the Samurai express awe at the strange sight of the underground city beneath Naraku, with Walter likening the skyscrapers to giant coffins. At the Government Office Building in Shinjuku, if Flynn elects to kill Kuebiko, Walter expresses disapproval, questioning if that was the right thing to do. Once the Black Samurai is captured in Ikebukuro, Walter becomes angered by Hugo taking credit for the task, a sentiment that Hope shares with him. He is further dismayed when they are forced to stand in the crowd at the Black Samurai's execution.

During the VIP rescue mission in Shinjuku on behalf of Sister Gabby, Walter carries the second masked man out of Kagome Tower and to Mikado Castle, briefly leaving the party. After the three are rescued, he asks Gabby who the three are and finds her knowledge on Tokyo to be suspicious. Even with Gabby's response that they are "vital to the kingdom's future," he asks what she means as he doesn't understand, only for her to ignore his question. He questions the new order to kill the Black Samurai who has apparently risen from the dead, as they are now tasked with assassinating a woman that was already killed once, and is shocked when the Ashura-kai's leader Tayama requests a meeting with Flynn.

Later on, they discover the Black Samurai is actually the leader of the Ring of Gaea, Yuriko, and she reveals she is the demon Lilith. Walter is swayed by her words, intrigued by a world in which the "strong can shape the world as they see fit," and stops Jonathan's attempt to strike her down. He heeds her words and decides to investigate the "face of true evil" beneath Roppongi, and asks his friends not to kill her until he returns. He is seen conversing with Hikaru in Ginza, and goes to the Florida Cafe to meet Fujiwara in order to learn how to get to the place Yuriko mentioned. However, the guard refused to let him enter until Flynn and the others arrived with the proof of membership (courtesy of Hikaru). He rejoins the group after Jonathan convinces him the demons will be too tough to handle alone.

After learning what Red Pills are made of in Reverse Hills, he is influenced by Yaso-Magatsuhi's gas, and declares he must make a confession: he is from a family of fishermen, but is scared of fish. He then excitedly declares that he "must tell everyone" and runs off, with the rest of the party succumbing to the effects of the gas. They awaken in the Hills building, and Walter confronts Tayama over his "utopia", revealing that Yuriko is a demon in the process.

After meeting the Four Heralds, he decides to defect from the ranks of the Samurai, viewing the new order in Mikado as no different than Tayama's control over Tokyo. Walter will ask Flynn to go with him to meet Lilith, and to meet him at the barracks. He will give his piece on how he doesn't wish to be bound to another man's rules and that following another person's rules won't necessarily makes ones own life better. He confesses he knows that what Lilith is doing may cause harm, but he sees no option other than to change the world from its current state. Agreeing to join him will cancel out Tayama and Gabby's main quests t
