Hibiki Kugenin/History

==Early History==
Not much is known about Siegfried's history. He comes from a wealthy family that used to own a Zaibatsu. There's a quote that says, "If there is land next to your house, you may not enter it might belong to Siegfried." His family owns a large amount of land. His love for music started at an early age and his love for fighting developed some time later in his life. The combination of these two loves is what eventually gave birth to his unique fighting style. His reason for joining Ragnarök was to find more remarkable fighters to challenge, and to use those fights as inspiration for his music. During that time, he met and befriended Thor. At some point in his life, he fell in love with a violin named "Duratin".
==Plot== 
==Ragnarök Arc==
===Siegfried Arc===
Siegfried is first mentioned by Niijima, who details the results of the Fifth Fist with accounts from other gangs, who call him a "zombie fighter". He first appears in person, writing music as he sits by a desk and chases Niijima when the latter comes to spy on his discussion with Loki. Though he appears to be hit by Niijima's attacks, he easily catches up with the leader of Shinpaku and chases him throughout the neighborhood while singing Mussorgsky's Night on Bald Mountain. He finally catches Niijima as he dives into a sewer, singing Beethoven's 5th Symphony.
===Final Clash arc===
Siegfried is just about to finish his musical composition at the docks when Kenichi and Miu suddenly catch up to him and demand from Loki where Niijima is. Infuriated, Siegfried demands to attack them to compensate for the music he lost, and possibly to pick up some new melody during the fight, and faces Kenichi alone, constantly countering his attacks while pretending to take damage from Kenichi's hits. He is placed in a vulnerable position by Kenichi and becomes unable to dodge the latter's then the unnamed Mubyōshi. After their battle, he goes on a journey to find himself. Niijima later convinces him to join the Shinpaku Alliance after being swayed by him, where he acts as the Alliance's combat leader, but mostly as Niijima's personal guard. When Berserker started attacking all the members of the Alliance, Siegfried tried fighting him only to be easily defeated to protect Niijima and has his unconscious body used by Niijima as a shield. After being healed by Kensei, he tries to leave and reveals he can fight of Kensei's anesthetic with sheer will power. He takes his job as Niijima's personal guard very seriously, threatening even his own teammates if they go against Niijima who he calls his "dear demon king". Siegfried appears to be honorable to a degree, having reprimanded Niijima to persuade Kisara to join Shinpaku through a more grandiose method rather than the usual blackmail. He tends to only dodge attackers until Niijima orders him to attack and even feels pride if he was able to help Niijima in anyway, even when Niijima used his unconscious body as a human shield.
When Kenichi is left to fight against Ryūto all on his own, Siegfried and the other members of Shinpaku take on his bodyguards and cheer Kenichi on to win.
==Yami/Yomi Saga==
===Spark Arc===
As the threat of Yami becomes apparent, Siegfried travels to Tibet for further training. When Li Raichi starts attacking the members from orders from Yomi, he steps in willing to sacrifice himself to save them. After Kenichi defeats her without injuring her due to his pride of not hurting a woman, her father Tenmon Li arrives, and the Alliance starts fighting him. Niijima shouts at everyone to not fight him due to him discovering that his level is as the same as Kenichi's masters. This is proven true as Tenmon defeats all of them with ease till one of Kenichi's masters arrive and saves them from getting killed.
===D of D Tournament Arc===
During the D of D tournament, he skies dives into the arena just in time to help Shinpaku which is short-handed due to injuries and is outnumbered fighting the Capoeira team. His training has made him virtually unbeatable; he is capable of dodging two people attacking at the same time with little effort, he can even turn his head a whole 180 degrees due to his training, a fact that makes Kenichi doubt his humanity. It is stated in this fight by Shio Sakaki that Siegfried specializes in a Go No Sen (striking last, hitting first) style of fighting and he is almost a master class in this technique. He could have actually defeated the entire Capoeira team including the leader by himself, however he hesitated because he was waiting for Niijima to order him to attack. After shocking everyone with his newfound power he collapses from severe lack of sleep due to him searching for the Shinpaku Alliance nonstop for three days. During the fight, Siegfried claims that he has no more weaknesses, not even a leaf, referencing the Legend of Siegfried. The Elder claimed that someday, Siegfried will definitely become a master class fighter.
After Fortuna tries to take the members as his own children, Siegfried and the other injured members from their fights alongside the arrived Natsu engage battle with the master opponent with Niijima giving them instructions on how to defeat him. With their combined efforts, they defeat Fortuna. as They are later all cheer Kenichi on to get up and defeat Shō Kanō.
===Yomi in School Arc===
As the school camping trip happens in Kenichi's school, Siegfried helps defend the classmates from Boris's Russian guards and takes them down from harming anyone (specifically Niijima).
===Okinawa Arc===
Siegfried appears later as the Alliance goes to Okinawa to take down a Yami base. However, even though they had the lobby at their hotel secure for Ryōzanpaku to go through, the masters evade them and leave the alliance to believe they had a peaceful night.
===Yami Transport Data Arc===
After returning home, Niijima managed to get some data on Yami and planned to give it to the police to clear Ryozanpaku's name. When the Alliance was getting overwhelmed by their opponents, Siegfried, Thor, and Freya jumped out of a plane and arrived to help fight (though Thor landed off course due to his hesitation). They fight their opponents respectively and show how far they've come and defeat them just as Kenichi's group arrives. When the politician reveals that he's a master Yami member and destroys the data Niijima acquired, the Alliance fights him with Sakaki's assistance from the bushes. After Ishida is defeated, they return home having completed their objective.
===Titan Arc===
Following the discovery of a Yami base, Siegfried and the rest of the alliance head out to the location with the masters. However, they are forced to stay due to the masters not wanting them to get hurt. As the masters head out, the limo that picked up the YOMI members from before arriving and everyone is shocked to see Berserker and a member named Lugh. Siegfried feels that it's almost natural that Berserker join since Ogata trained the other Ragnarök members and takes note that Ryūto is also there in the limo. As Lugh decides to test out the strength of the alliance, Ukita charges at him only for Siegfried to save him and states he had a bad feeling when he first saw him and realizes he doesn't see his opponents with his eyes, but rather, he sees them with his hands and ears and discovers that Lugh is blind. Siegfried then decides to charge at him due to his defence being strong and asking for him to be hit and Lugh does as he asks and snaps his neck. As Thor attempts to avenge him, his arm is broken by Lugh and Siegfried saves him with a kick and snaps his neck back into place admitting if not for his training in Tibet he'd be dead. He then notices that Lugh's fighting style revolves around locks. He continues to notice that Lugh is able to fight so well as Takeda steps in to fight him and takes notice that he's using a similar fighting style similar to his own. As Takeda prepares to sacrifice his left arm, Siegfried doesn't interfere, noting it's his fight, but is shocked to see Kenichi interfere, stating he can't just let his friend hurt himself in a fight like this, prompting Siegfried to agree since they are Katsujinken users. As Lugh decides to leave, he promises to crush Takeda first next time.
He later attends the amusement park with the rest of the Alliance. He then talks with Thor when Thor believes he saw Tanaka, but Siegfried doesn't see anyone. At night, as Siegfried composes a song, he is interrupted by Hermit. He notes to himself that he always suspected Hermit being in Yomi even though he said he should have joined his side and jumps up to him stating he'll force him back as his comrade and that he isn't the type to preach to bad children who don't listen.
They continue to fight as Siegfried complements his improved skills as Hermit does to Siegfried. Siegfried then asks why doesn't he play the "ensemble of friendship" with them, but Hermit says it can't be helped due to how things ended up and all things must come to an end. Siegfried disagrees and clashes with him stating there are some things that will never end, and this surprises Hermit as part of his coat is cut. Their battle continues with both sides complimenting each other's skills as Siegfried says he won't speak to someone as an equal who won't accept friendship which Hermit refuses to do so, and they clash. Eventually, Siegfried is defeated by Hermit noting the slight difference in strength, demanding he realize what friends do to help polish one's skills. Hermit acknowledges his increased skills but tells him to not try to look down on him after losing. Siegfried just scoffs stating his reason that he still has a ways to go and if he'd fought with Kenichi now, he would definitely lose, much to Hermit's annoyance. As the amusement park continues to burn down, Siegfried along with the rest of the alliance leave after everyone else has been gathered. 
===The Eternal Sunset Arc===
Days later, Niijima greets most of the alliance after the battles and points out how Rachel and Chikage haven't gone to school lately and Tanimoto is going to school like nothing happened. When asked about Kenichi and Miu's whereabouts, Niijima states that they went to see the people who got out of the darkness: Ryūto and Rimi. Several days later, Siegfried along with the rest of the captains, gather at the base waiting for Kenichi and Miu. Kenichi and Miu notice that Apachai and Shigure have been waiting at the base asleep the whole time, waiting for everyone to show up. Shigure then wakes up and tells them that she has something to give them, and then takes the bag away from a sleeping Apachai and hands all of the captains the arm protectors that she made for them, then demonstrates how strong the gear is against a weapon, which amazes everyone.
Later, Kenichi and Miu inform him and the others of Shigure's capture, shocking everyone. Siegfried states that Yami's "overture" is coming to an end, which will probably lead to a sudden development. Once the alliance learns of her location, all the alliance members set out with Okamoto to find her. Siegfried was then present as he expresses his desire to help everyone fight against Yami. Just then Okamoto enters to tell them of their arrival and the Shinpaku Alliance readies for battle.
After Okamoto incapacitates the soldiers on the land, Siegfried and the others head for land into the forest. Once Yami soldiers show up, Siegfried engages battle with them with the others and advances forward with the rest as Okamoto decides to stay behind to hold them off. Once they reach a waterfall, they are confronted by the YOMI disciples. Siegfried calls out to Niijima, who tells Kenichi and Miu that they'll take advantage of the commotion and move on ahead. After seeing them launch towards them, Niijima tells Miu and Kenichi for them to take advantage of the situation and run. Though hesitant, the trio leave after Siegfried and the others encourage them to move ahead. After they leave, Siegfried and the others lunge towards the Satsujinken disciples.
He then battles Marmaduke's and Raki's disciples and deflects their attacks and Mildred's disciple's arrows back to her direction. He then warns the others of reinforcements arriving for YOMI. Hyōgo then proceeds to stab Thor on the shoulder and Siegfried comes to his aid but ends up being slash by Hyōgo's fellow kodachi disciple. As they continue to be overwhelmed by the armed division, Chikage suddenly defends them on the grounds that the armed division has no honour ganging up on them. Chikage replies that they will be supporting the Shinpaku Alliance, albeit temporarily, in order to protect their masters' pride.
Once they start to overwhelm the weapons team Hyōgo starts to have them work together more effectively. Just then, two masters: Sōgaku Chin (crescent moon spade) and Ortal Sin (jamadhar) arrive and begin to put pressure on them. However, Ryūto, Renka, Koan Shokatsu and Genson Ryu, Renka's fellow disciples, also arrive and attack the enemy reinforcements. Once Ryūto tells them what to do, Siegfried fights alongside the alliance against Ortal Sin.
They all defeat the masters as after the armed forces retreat, they celebrate their victory.
===Epilogue===
In the Epilogue, Siegfried, alongside Tsuji and Thor, start a rock band and become a huge hit.
