Shobu Kirifuda

Shobu Kirifuda is the original and longest appearing central protagonist of the anime and manga series.

He was later replaced by his younger brother, Katta Kirifuda in the Victory and Versus Saga and later on, his nephew Joe Kirifuda.

Before Katta's dueling era, he mysteriously disappeared in the climax of a war against Adam without any memories of Duel Masters. He eventually returned in the Duel Masters Versus season to apparently assist his brother under the shadows in certain circumstances as a recurring character in the season.

Appearance
Shobu was a young boy with black hair that swept backward and black eyes. His appearance is noted to be similar to his father, Shori Kirifuda. Even his younger brother, Katta Kirifuda shares some of his appearances(except for hairstyle, hair color and eyes). When the season progresses, he grown a bit taller and more mature and in his final appearance as a kid, he is close to his younger brother Katta's current age appearance of 14.

His initial outfit consist of a long-sleeved purple shirt, light brown pants and knee high boots before replacing his shirt with a short sleeve one. He later wears an orange shirt with blue linings. He wears a deck belt on his waist. He lost his deck belt in the collapsing tower when he defeated Adam and fell into the sea. It was later retrieved by the surviving duelists after the war. As an adult in his early 20s, he has a noticeable growth spurt, standing even taller than Katta when they were reunited. He also has a more mature appearance, even though some of it does not change. In the beginning, he wears an eye patch that covers his right eye. He no longer wears it when he was watching the semi-finals match of the national tournament. Even though he was no longer in the World of Duel Masters due to the events in Star Cross, his current appearance was still recognizable by a few, shown when Kojiro Sasaki was surprised to see him in the tournament stadium and Benny Haha recognizing him before collapsing after Shobu knocks him down.

His casual outfit consist of a long sleeve red shirt with white outlines, blue wristbands, light brown trousers and brown shoes, similar to his previous outfits in his youth. He dons a white coat in several occasions. He attaches his deck case on the left side of his waist. In the opening sequence in the Versus Revolution season, he wears a cloak in a similar way as his father. When he was observing the battle of Katta and Team Hamukatsu against Basara and Dormageddon X, Forbidden Armageddon, he wears a black formal attire. His appearance does not change much after a 12 year time gap.

Personality
Shobu loves to duel more than anything, especially with his favorite card, the Bolshack Dragon. Shobu keeps a positive attitude throughout the season, insisting on dueling for fun as opposed to simply winning. When his friends are in danger, he fights to protect them and can get serious in duels. Like Katta, he was able to hear the voices of the cards, even though he was afraid of them at first. He also forms friendly relationships with the creature spirits he partners with, even protecting them. At certain points, duels that involve creatures being materialized into the real world and major destruction, he was left frightened and in certain points, traumatized by the aftermaths.

In the Versus season as an adult, he still retains his calm and cheeky attitude towards his brother Katta despite being serious due to his years of absence. He sometimes has no trouble in pointing out and poking on Katta's weaknesses or making crude jokes in front of him, much to Katta's annoyance. He still regardless loves his brother, shown in a childhood flashback when he witnessed Katta in a vegetative state and shedding tears. He even gives Raging Dragon Lord to Katta at the young age before his departure, in which the card later turns into 3 psychic creatures and evolves to Gaial King Dragon, Raging Dragon Lord years after his disappearance. He even went all the way to watch over Katta after regaining his memories and helped him when the situation calls, even personally watching Katta's match against Gyou in the national tournament, despite the risk of his identity being known and exposed by others.

Despite not being as strong as before, he was still capable of holding himself out when needed and have utmost confidence in his abilities. His dueling skills are still considered as powerful, in which Katta even noted on. As an adult, he was quite intelligent in many areas, as he was able to track Katta's progress in the Duel Masters World and the National Tournament, noting on Katta's potential rivals and their strengths. His perception ability also improved, as he was able to detect Gyou's actions and guessed out his true intentions in just one look, allowing him to think and act one step ahead. During the events when Dokindam X, The Legendary Forbidden was released by Basara and had witnessed the events himself, he even prepared a card and challenges for Katta as a measure to protect his brother from dangers. His capabilities and knowledge about the Duel Masters World makes him a reliable and powerful ally of Katta and his friends.

One of the most distinct trait is that he did not want anyone to get hurt or die in a duel. This was evidenced in a war against the Fua Duelists and being part of the major war in both the human and creature world to save the future of Duel Masters. This trait was still dominant even as an adult when he knocked Benny Haha down to prevent the remaining finalists from getting hurt and his near death experience in his youth, losing his memories in the aftermath. Even Katta also inherited this trait in his duel against Lucifer.

He dotes his nephew Joe Kirifuda, occasionally visiting him despite his busy schedule at work. He also gives notes and guidance to Joe in terms of dueling in place of Katta.

He was first shown in Katta's childhood memories about their happy times before the incident and in Mimi's flashback when she compares how different the two brothers are. Even Yohdel and Bucyake mentioned about him in front of Katta, much to Katta's annoyance. Katta was then being called as Shobu's brother by others until Katta had proven that he was a duelist on his own right and had shown his willingness to fight for others and the creature world, like how Shobu have done in the past.

Duel Masters Versus

In episode 31, he sent Lulu Takigawa a message, under an alternate name "Mr Match" about Katta's location. During Katta's duel against their mother, Mai Kirifuda, Mai compares Katta as a splitting image of Shobu in his younger years, never giving up and have belief in themselves.

In episode 33, he dueled his younger brother Katta Kirifuda as his final opponent before the nationals and revealed to Katta the truth about what happened years ago. Using his Bolshack Masters, Trump Dragon's effect, he breaks all of Katta's shields in a single attack.

He congratulates Katta on his victory, noting that he was glad to see Katta becoming stronger in the final rounds of the tournament. Remembering his younger years and his dueling journey, he reminded Katta that one more person was waiting for him even though he had overcome tough matches and rivals.

However, he managed to witness Katta being defeated by a Dokindam X influenced Basara through his surveillance system and decided to help as the situation cannot be ignored.

He sent a letter addressed to Katta regarding the situation related to the secret organization in Duel Masters Land, revealing that he has a card that might be the key to fight the Invaders and his location. Katta accepted his request with enthusiasm as he was the only person left that they can rely on and was awaiting to see him again since their last meeting. When Katta (with Lulu, Hamukatsu, Hokaben, Benchan and Bucyake in tow) heads towards his location, he looked at the night sky, concerned about Katta's safety and the upcoming battle.

He encountered Katta and his friends, with Gyou included despite what happened last time (Gyou working with Benny Haha but Shobu partly disrupted their overall plans in the National Tournament in VS). He explained to Katta about his reasons asking him to visit and gives Katta Bolshack Dogiragon, which he obtained during his travels and research about his own Bolshack Dragon and Katta's Dogiragon, Flaming Revolution. He showed Katta the ancient records and the book he obtained during his travels but swiftly noticed Gyou taking a photo of the record. Suspecting Gyou's true intentions and knowing the limited time both he and Katta have, he managed to deceive Katta to engage in a duel in order to learn how to used the card properly.

During the duel, he decides to go all out on Katta and telepathically communicate to Bolshack NEX (similar to Katta's ability when he was in Victory Mode), though they got into a petty argument about being slow. He remembered the time when he first met Bolshack's spirit and during the time of the battle in Adam's tower. He then summons his new Bolshack trump card, Überdragon King Bolshack by its Gravity Zero effect. He asked the rest of the group to leave them alone, in which his actual intention is for them to stop Gyou's plans and to cheer Katta up from his depression by reminding him of having a fun duel. During the duel, his skills was enough to make Katta use Bolshack Dogiragon's Revolution 0 Trigger ability as the last minute save. Upon seeing the 2 Dogiragons in the duel zone, he was happy to see Katta's growth as a duelist and let himself be defeated. His plan worked as the others managed to stop Gyou's schemes, which results in the organization's plans being foiled again.

He also told them to be careful now that the organization have the information of the other Revolutionary Legend card, they will likely be targeted more often. It was eventually revealed that Benny Haha had been holding a grudge against him for years and wants to get revenge against Shobu and to the extent, Katta for foiling his plans repeatedly by targeting Katta through various schemes, even through the use of targeting Katta's allies. However, his plans of getting revenge were again destroyed by Basara. The grudge was settled by Katta himself during the final battle.

Trivia

 * His surname's kanji of 切札 (Kirifuda) literally means "The Trump Card", "The Ace Card" or "The Winning Card". His name's kanji of 勝舞 (Shōbu) is a combination of his father's name 勝利 (Shouri) meaning "Victory" and his mother's name 舞 (Mai) means "Dance", thus Shōbu means "Victory Dance" or "Dance of Victory". The pronunciation しょうぶ (Shoubu) is also a pun from (勝負) Shōbu which means "Win (or) Lose" and from there derived the meanings: "Duel".
 * This trend runs in the Kirifuda family, as Shobu's younger brother 勝太 (Katta)'s name means "Great Victory."
 * While chasing Zakira in season 3, Shobu falls into a hole and burns his purple shirt. He later replaces it with an orange one.
 * As an adult, he shares the same voice actor as Kaito Tenjo from Yu-Gi-Oh! Zexal and Yu-Gi-Oh! Arc V. His voice actor Koki Uchiyama also voices Ventus and Roxas in the Kingdom Hearts series.
 * He was the second main character in the main series to lose his memories in both the anime and manga series after Hakuoh.
 * He is the second main character of the past generation to return in Katta's generation. The first is Mimi, which was later followed by Benny Haha and Zakira.
 * In the Versus Saga, he only appear if Katta and his friends were in a dire situation, mostly through relaying his letters/message to them and arranging a place to meet them instead of approaching to them directly. This might likely due to avoiding unwanted attention as he was thought to be gone for more than 10 years, though in a few exceptions if the situation involves his enemies or events that might affect the creature world. This had changed after the timeskip and became one of the supporting characters of the series.
