Katz

Katz is a Japanese player whose blood-manipulating class grows from the epic Blood Warrior into the ancient Beriache's Knight. Initially notorious for wealth, arrogance, and public displays, he joins the Overgeared Guild to obtain Grid's equipment. Years of collective war turn that self-interest into pride in the guild and a wish to share Grid's burden. His mature role combines battlefield blood control with stewardship of the vampire cities on Marie Rose's behalf. (Chapters 8–9, 443, 1017–1018, 1403, 1516, 1750, 1848, and 2026)

Biography

Pagma's Legacy and Winston

Katz enters public attention as a rapidly rising level-203 warrior who reveals his newly purchased epic class on television. He boasts that Blood Warrior and his own talent will carry him to the top of the rankings, then displays expensive enhanced equipment in town simply to attract notice. When his rank stalls despite relentless solo hunting, the failure wounds the pride he uses to distinguish himself from more successful siblings. Rather than reassess immediately, he tries to solve the problem through harder hunting and better purchases, establishing both his ambition and the limits of wealth without judgment. (Chapters 8–9, 53, and 73)

Reidan and the Overgeared Alliance

Katz approaches Grid because ordinary markets cannot supply the growth equipment he wants. Although selfish and accustomed to getting his way, he recognizes his weak negotiating position and asks what service would qualify him for an item. Lauel uses that desire to recruit him. Katz accepts guild control and even calls himself Grid's servant, not because he has suddenly become humble, but because the exchange offers the strength he values. This pragmatic entry gives him a community whose meaning he only understands later. (Chapters 443, 454–455, and 467)

At Siren, Katz fights on the water clan's side and uses streams of blood to herd opponents into an explosion. He also tries to respect non-player characters because Grid does, though his cheerful admission that he enjoys combat and killing only frightens them. The episode captures his transitional state: loyalty is still imitative and reward-driven, yet he is already modifying his conduct for the guild's reputation and using his dangerous temperament in its defense. (Chapters 466–468 and 470)

Kingdom Building and the Great Demons

Against Earl Cray, Katz turns the vampire's own blood-made tails against him. Cray can reclaim only the two tails he fully controls, so Katz's intervention strips away part of the direct descendant's signature offense and exposes a weakness that brute force had not reached. The victory confirms why Blood Warrior is feared in mass battles: once blood is present, Katz can appropriate even an enemy's formed blood techniques rather than merely create projectiles of his own. (Chapters 718–719)

East Continent and Imperial Reckoning

The empire war gives Katz a belonging larger than his individual ranking. He kills thousands of enemies, dies repeatedly, and regards the empire's dismissive treatment of the conflict as an insult to the companions and nation for which he fought. He chooses a defensive reward rather than another purely offensive advantage, reasoning that blood absorption already gives him recovery but not enough durability. That choice and his acknowledgment of Grid's superiority show practical humility replacing the assumption that class and money alone make him supreme. (Chapters 1017–1019)

Apostles, Dragons, and the Overgeared World

The release of the vampire race upgrades Katz's epic class to an ancient one. Blood Warrior's defining battlefield condition is removed: instead of requiring his own or another being's spilled blood, Katz can consume mana to generate blood and use skills such as Blood Tornado anywhere. The change makes him a consistently powerful fighter, but it does not restore his old claim to be the best. He immediately measures himself against other exceptional players and treats Grid as the standard he supports rather than a rival he expects to surpass. (Chapters 1403 and 1406)

During the Great Human and Demon War, Katz becomes a rapidly rising face of the guild. He apologizes to Kujarak for his past attacks, accepts correction without turning it into another contest, and hopes that players across the world will grow strong enough to share Grid's burden. His calm behavior marks genuine maturation: the guild he joined for items has become a source of responsibility, and competition becomes compatible with respect and collective survival. (Chapter 1516)

Baal, Asgard, and the Complete Ending

Katz's ancient class leads him into Beriache's legacy. Guided by her soul during a class quest, he removes the artificial blood that resurrects corpses and later overrides the blood control of Beriache's corpse, pulling Grid's blood and the Blood Field away from it. The corpse attacks him as the greater threat, and Grid protects him in return. Katz then spies on Amoract, finds Beriache's soul, and awakens enhanced class functions while trying to stop the newly freed great demon. (Chapters 1749–1750, 1753, and 1848)

By the latest period his class is Beriache's Knight, but the failed betrayal and death of Beriache leave him serving Marie Rose. He manages vampire settlements and internal affairs rather than acting as her intimate confidant, and he can issue quests to the vampire race when a search is required. Grid asks him to conserve his strength for the coming war, confirming that Katz remains an active Overgeared asset whose authority now includes civil administration as well as combat. (Chapters 1916 and 2026)

Appearance and personality

Katz is introduced as an Asian youth around Grid's age with well-trimmed hair. Early appearances emphasize polished weapons, expensive armor, and the red, vascular transformation Blood Warrior applies to a weapon rather than providing a stable physical portrait. After changing species, he gains the general vampire traits discussed around the transformation, but the selected evidence does not establish a unique later facial description. (Chapters 8–9 and 1403)

He begins arrogant, conspicuous, territorial, and proud of his family's wealth. Failure exposes deep insecurity about being lesser than his siblings, while combat gives him obvious pleasure. Katz is nevertheless pragmatic enough to lower his posture when he needs Grid and disciplined enough to work within Lauel's rules. Repeated wars change his competitive outlook: he apologizes for past misconduct, respects uncompromising allies, and wants collective growth. He remains blunt and does not flatter Marie Rose, which suits his later administrative rather than personal relationship with her. (Chapters 53, 443, 467, 1516, and 2026)

Abilities, classes, and skills

Katz's power centers on treating blood as a controllable combat medium. His class begins as the epic Blood Warrior, becomes ancient when the vampire race is released, and later develops through Beriache into Beriache's Knight. Across those forms, he specializes in draining life, shaping blood into weapons and fields, taking control of blood-based attacks, and exploiting battlefields where many beings have already bled. (Chapters 8–9, 718, 1403, 1750, and 1848)

Blood Warrior

The original Blood Warrior passively changes a held weapon into a blood-covered form that absorbs health in proportion to attack power. Katz can animate shed blood as streams, redirect trajectories, detonate them, form swords, or create larger attacks such as Blood Tornado. This makes sustained hunting easier and turns crowded battles into favorable terrain. His control can overpower an enemy's imperfect blood construct, as when he seizes two of Earl Cray's four tails and makes them attack their owner. (Chapters 8–9, 467, and 718–719)

The early class has a strict resource condition. Katz must use his own blood or blood already present, leaving him close to an ordinary warrior before anyone bleeds and forcing him to accept risk or prepare a suitable battlefield. After the class becomes ancient, he can spend mana to produce blood directly. The upgrade removes that environmental dependence and lets him create Blood Tornado on an apparently bloodless field, though it adds mana expenditure rather than making the techniques costless. (Chapter 1403)

Beriache's Knight

Beriache's soul grants Katz blood authority greater than the control exercised by her animated corpse. He diverts Grid's spilled blood, drains the artificial Blood Field that repairs the corpse, and deprives repeatedly resurrecting bodies of their false blood. The authority attracts retaliation because it dismantles the opponent's resource at its source. It also permits transformations such as becoming smoke, forging a sword from his own blood, and surrounding the battlefield with blood that obscures an enemy's senses. (Chapters 1749–1750 and 1848)

When Beriache is identified as his loyal target, the class awakens and modifies existing skills. A pursuit technique becomes Protector of the Last Guardian of Hell, combining defensive increases, critical immunity, weapon and attack-speed improvements, guaranteed critical hits, and stronger critical damage. This is a conditional awakening tied to Beriache's presence and will, not proof that every listed benefit is permanently active. By chapter 2026 the class remains ancient under the name Beriache's Knight even though Katz now serves Marie Rose and directs vampire civic quests. (Chapters 1848 and 2026)

Relationships

Grid is first a source of coveted equipment and later Katz's leader and trusted combat partner. Katz joins the guild to earn his work, but imperial and demon wars turn the bargain into belonging. In Beriache's battle, Katz tells Grid to fight freely while he controls the blood, and Grid immediately trusts him and protects him from the corpse's counterattack. (Chapters 443, 467, 1017, 1516, and 1750)

Lauel recruits Katz by making guild membership the price of access to Grid's equipment. Katz initially dislikes rules and interference, but accepts Lauel's use of him and becomes part of the organization Lauel administers. By the later story, Katz handles the vampire cities within that broader political structure rather than remaining a free-roaming ranker. (Chapters 443, 454–455, and 2026)

Marie Rose becomes Katz's current superior after Beriache's failed betrayal and death. Katz reports on vampire cities for only a few minutes each week and is not her confidant, but manages the race and can mobilize its members through quests. The relationship is functional stewardship, not personal intimacy. (Chapter 2026)
