Berserker was the Second Fist of Ragnarok before it was disbanded and is now a member of Yami's disciple group Yomi. He is a tall, muscular young man with spiky dark blonde hair styled in the back, wearing a red open jacket and gloves.
Berserker is often seen chewing bubble gum and seldom speaks. Despite the chaos surrounding Ragnarok, he maintains a calm demeanor and rarely loses his cool. Known as the most fearsome fighter within Ragnarok, Loki even speculated that Berserker could be a superior First Fist compared to Odin, though this may have been a ploy to sow seeds of betrayal.
However, Berserker shows no ambition for leadership roles and admits to fearing Odin, believing him to be much stronger. During his match against Hermit, Berserker claimed to fear boredom more than losing. When in Berserker mode, he becomes significantly more brutal and sadistic, attacking without restraint and laughing maniacally.
Berserker typically remains silent in the background when others converse. In one instance, he plays poker with Loki, who jokingly mentions restarting Ragnarok, declaring the winner would become the leader. After cheating to get a four-of-a-kind, Loki shocks himself by seeing Berserker had a Royal Straight Flush, but Berserker leaves uninterested.
Later, Berserker begins eliminating key members like Takeda, Ukita, and lower-ranked fighters. Chasing Niijima, he falls into a trap but quickly overcomes it, defeating Siegfried and nearly drowning him before leaving him for Akisame and Sakaki to rescue.
During the attack on Shinpaku Alliance, Loki instructs Berserker to lead his "New Eight Fists," but Berserker defeats them all, including Loki, stating his true intent was merely to get closer for an attack.
Hermit challenges Berserker out of anger for taking down Loki. Initially, Berserker struggles against Hermit's abilities, forcing him to use unconventional techniques. Eventually, he enters Berserker mode, overpowering Hermit until ultimately being defeated. Despite severe injuries, Berserker refuses to concede until Kenichi intervenes, advising him that defeat teaches valuable lessons. Berserker warns Kenichi about Odin before succumbing.
Later, Berserker appears to join Yomi, seen among three candidates selected by Kensei. Following Silcardo Jenazad's death, Ogata Isshinsai discusses events with his disciples, amused. Rimi recalls her encounter with the Demon God Fist while Berserker remains in the shadows, chewing bubble gum impassively.
Berserker makes his formal re-entry standing behind former leader Asamiya Ryuuto during a Yomi gathering called by Kushinada Mikumo. When shurikens are thrown at the disciples, Berserker catches them with his mouth, forming bubbles around them, pondering the battles the others have faced.
