Biban

Biban is the second-generation Sword Saint, founder of the Matchless Style, and a long-serving member of the Tower of Wisdom. Initially introduced as an eccentric swordsman testing the modern Pioneer, he becomes Grid's teacher, rival, and beneficiary. His centuries-long attempt to turn himself into a sword nearly destroys his identity, but Grid helps him redefine the relationship between swordsman and weapon; Biban then becomes an Absolute recognized as the Sword God and assumes a larger share of humanity's defense against dragons. (Chapters 1125–1130, 1480–1484, 1503–1504, 1651–1652, 1752, 1775, 1777–1780, 1826, 1910–1912, and 1938–1940)

Biography

Yangbans, Gods, and New Legends

Biban descends from the Tower of Wisdom to assess the Pioneer and first mistakes Mercedes for the target because her Keen Insight and disciplined swordsmanship catch his attention. Once he recognizes Grid, he identifies the status carved into him, conducts a formal test, and introduces himself as the second-generation Sword Saint. His initial dismissal of sword dances as ritual movement is shaken when Grid's techniques cut him for the first time in decades. Biban rewards that potential with the Matchless Heart Technique and modified swordsmanship, beginning a relationship in which blunt criticism, misunderstood instructions, and genuine generosity repeatedly coexist. (Chapters 1125–1130)

Biban also treats the Sword Saint lineage as a responsibility rather than private property. He explains how body, technique, and heart form a complete swordsman, permits Grid to pass the Matchless Heart Technique to qualified allies, and challenges Kraugel for rejecting the inherited style. His anger comes from seeing Muller develop Biban's teachings into historic greatness while the current Sword Saint appears to abandon them; he later accepts that Kraugel may need to create a different answer. The shift from demanding imitation to trusting a successor's judgment foreshadows Biban's own need to stop defining himself only through the sword he inherited and perfected. (Chapters 1216, 1221, 1226–1227, 1310, and 1336)

Apostles, Dragons, and the Overgeared World

When Biban returns to spar with Grid, he begins as the superior swordsman and neutralizes complex sword dances by reading intersecting trajectories, twisting sword energy, and realizing his mental world. Grid's items, Shunpo combinations, and willingness to use every available method eventually cut off Biban's hand. Biban accepts the defeat as fair, praises Grid's sword dances as genuine swordsmanship, and risks a loss of status by defending that verdict before the tower. The duel converts condescension into mutual recognition. It also creates the Overgeared Sword Tower, where Biban temporarily teaches Singuled and other swordsmen, proving that his centuries of insight can strengthen people outside the formal Sword Saint succession. (Chapters 1480–1486, 1495–1496, and 1570)

His battles reveal both courage and a dangerous internal process. Against Zeratul, Biban traps the god inside a curtain of sword energy that is also his mental world, reads the god's convictions through their collision, and accepts a near-fatal exchange to keep him occupied until the descent ends. In hell, Biban kills Valefor despite environmental penalties, but his companions notice that the endlessly vibrating sword energy inside him is destroying judgment and memory. He has spent centuries sharpening body and mind into a weapon capable of cutting a dragon because Hayate cannot safely risk himself. What looks like absent-minded comedy is therefore the visible cost of a deliberate, self-erasing preparation. (Chapters 1503–1504, 1646, and 1651–1652)

Baal, Asgard, and the Complete Ending

The process reaches its crisis after Biban cuts through Trauka's will. He becomes a complete sword at the cost of consciousness, leaving an empty mental world in which the weapon has no master and will eventually dull. Grid enters that world and refuses to accept the sacrifice as complete, offering Twilight and insisting that Biban rely on a sword made for him rather than reduce himself to one. Their confrontation restores the distinction between swordsman and weapon. Biban awakens with a stabilized mental world, uses Grid's sword and divinity against an attacking dragon, and is recognized as a new Absolute. The system names him Sword God because his sword itself has reached god-comparable power, not because worship or self-proclamation grants the title. (Chapters 1752, 1775, and 1777–1780)

As Sword God, Biban declares that he will share Hayate's burden and helps end the Tower of Wisdom's life of complete withdrawal. His Broken Sword can manifest the indestructible dragon weapon formed in his mental world, change size, cut draconic will, and kill powerful illusionary bodies in a single stroke. He fights in the campaign against Baal, helps restrain dragons and divine opponents, and arrives rapidly wherever the Overgeared alliance needs an Absolute swordsman. The role remains dangerous: Kubartos exploits the structure of Biban's mental world, breaks it, and leaves him critically exposed, proving his new status does not create invincibility. He survives and, alongside Muller and Kraugel, contributes sword attacks to the final struggle against Asura. (Chapters 1802, 1810, 1812, 1814–1817, 1824–1827, 1829, 1850–1851, 1884, 1886–1887, 1910–1912, 1938–1940, 2002, and 2051)

Appearance and personality

Biban is an old man with gray hair that shines nearly white in moonlight, sharp gray eyes, and a trained body capable of overwhelming physical strength. He often wears a robe when moving outside the tower. His ordinary atmosphere and unremarkable manner can hide his status, but when he trusts his sword completely he displays the calm bearing of an Absolute, without visible doubt in his own skill. After Grid restores him, his once-fading eyes become deep and mellow, reflecting the stabilization of a mind that had been eroded by constant sword-energy vibration. (Chapters 1126–1127, 1481, 1495, 1779, and 1938)

He is proud, blunt, temperamental, and almost comically poor at reading matters unrelated to swordsmanship. He evaluates people too quickly, gives instructions that are easy to misunderstand, and can shift from profound teaching to absurd behavior within a conversation. Those flaws coexist with humility before demonstrated skill. Biban admits fair defeat, revises his view of Grid's sword dances, respects Muller's greater historical talent, and eventually trusts Kraugel's independent path. His deepest trait is responsibility: the extreme decision to become a sword is misguided, but it arises from a willingness to protect Hayate, the tower, and the world at his own expense. (Chapters 1127–1130, 1480–1484, 1570, 1777–1780, and 1886)

Abilities, classes, and skills

Biban's abilities arise from the Sword Saint class, centuries of continuous practice, the Matchless Style he created, a realized mental world, and his later status as an Absolute Sword God. He has extraordinary sword energy, physical strength, insight into any sword technique, Heart Sword, and universal compatibility with sword-shaped weapons. His strongest development also produces his greatest risks: sustaining vibrating sword energy damages his body and mind, altering an active mental world can cause internal injury, and dragon-class opponents can exploit or shatter that world. (Chapters 1127–1130, 1481–1483, 1503, 1603, 1652, 1777–1780, and 1938–1940)

Matchless Heart Technique and swordsmanship

The Matchless Heart Technique circulates sword energy throughout the body so that it does not readily run dry. Biban builds the Matchless Swordsmanship on that foundation, using wind pressure and sword-energy control to twist incoming trajectories, defend intersecting attacks at their shared points, and strike effectively even at grappling distance. His physical strength is exceptional, while centuries of practice give him technique beyond Muller's prime by the time he spars with Grid. As a teacher he can lift restrictions on inherited swordsmanship, modify techniques, and identify how another swordsman should integrate different systems. These benefits require comprehension and practice; Grid's low initial technique level and Kraugel's rejection show that transmission alone does not confer Biban's mastery. (Chapters 1127–1130, 1216, 1221, 1310, and 1481)

Heart Sword and mental world

Biban's will is a sword. Heart Sword lets him recognize targets and cut through intent, space, or other non-ordinary objects, while his realized mental world surrounds enemies with innumerable blades and can isolate them from normal time and space. He can modify its recognition rules, but changing an already expressed mental world shakes his mind and causes bleeding. Zeratul resists the blades with fighting energy, and Kubartos later turns the structure of the sword-filled world against him and breaks it. Biban's early practice of vibrating near-infinite sword energy keeps every edge ready to cut a dragon, but the unending vibration progressively destroys memory, judgment, body, and identity. Thus his signature system is both the source of his transcendence and a documented self-inflicted failure condition. (Chapters 1481–1483, 1503–1504, 1652, 1777–1779, 1814–1816, and 1938–1940)

Sword God, Broken Sword, and latest state

Grid helps Biban recast the sword in his mental image as a weapon he wields rather than the totality of his being. This restored relationship allows him to borrow Twilight, harmonize sword energy with Grid's divinity and Dragon Slayer energy, and wound a dragon before the system recognizes him as an Absolute Sword God. Broken Sword is the later physical focus of that mental weapon: although its visible blade is incomplete, Biban can extend it to enormous size, use it as a grappling anchor, and manifest the dragon weapon formed with Grid, which cannot be broken in the ordinary sense. He remains extraordinarily effective against dragons because sword, Grid's divinity, and Dragon Slayer energy interact to bypass several draconic advantages. He is not invincible; Dragon Words can restrain him, old dragons can seriously injure him, and damage to his mental world still threatens his combat state. (Chapters 1778–1780, 1814–1817, 1826, 1851, 1910–1912, and 1938–1940)

Relationships

Grid is Biban's student, rival, smith, and eventual rescuer. Biban gives him the Matchless Heart Technique and repeatedly evaluates his swordsmanship; Grid repays that trust through teaching-by-conflict, equipment, and the intervention that saves Biban's identity. Their relationship matures when Biban accepts defeat and when Grid persuades him that relying on a sword does not diminish a swordsman. (Chapters 1126–1130, 1480–1484, 1570, and 1777–1780)

Hayate is Biban's leader and the person whose burden he tries to assume. Biban recognizes that humanity's first Absolute cannot be casually risked, so he spends centuries preparing to cut dragons in Hayate's place. Hayate's caution unintentionally helps drive him toward self-erasure, but both reject blame after the crisis, and Biban's promotion finally lets them share the tower's responsibility. (Chapters 1221, 1558, 1752, and 1777–1780)

Kraugel is a later Sword Saint whose refusal of Matchless Swordsmanship initially infuriates Biban. Their disagreement becomes productive: Biban learns that a successor need not repeat Muller, while Kraugel continues using Biban as a standard and sparring partner. By their later training, Biban can seal an Absolute's strength and still expose flaws, yet chooses to trust Kraugel to understand his own weaknesses rather than lecture him. (Chapters 1310, 1336, 1604, and 1886)
