Yu Sae-Jung's Growth Broadsword

Yu Sae-Jung's Growth Broadsword is an Orc-made weapon designed to recognize a wielder and continue growing alongside that person. Kim Sae-Jin gives it two C-level attributes, Growth by Absorption and Owner Recognition, and enters it in the final round of a blacksmith tournament, where its Mana resonance demonstrates the bonding mechanism.

History

Tournament unveiling

The weapon appears as the Orc Blacksmith's final-round entry in an open invitational tournament. Its hilt combines blue and red coloring, its pure-white blade bears the intricate carvings associated with the Orc's forge, and its proportions allow both cutting and stabbing. It is initially criticized for lacking the immediately visible special effect of a rival weapon, prompting the absent blacksmith to explain that he wanted a weapon that would not have to be discarded as its owner became stronger. He asserts that this blade can grow with its owner. (Chapter 38)

A judge tests the claim by infusing Mana into the sword. The blade absorbs it cleanly and hums in matching resonance. Sae-Jin warns her through his Orc identity not to maintain contact too long because the sword might recognize her as its new owner. The internal account identifies the two embedded attributes as C-level Growth by Absorption and Owner Recognition, made possible through the horns of Treynos. Yu Sae-Jung watches the demonstration with intense interest and is framed as the weapon's intended next owner. The item brief records it as acquired for her, but the supplied chapter does not show the later handover, payment, or first use in her hands. (Chapter 38)

Abilities and properties

• Growth by Absorption: The C-level attribute allows the sword to grow together with its recognized owner, addressing the problem of a Knight outgrowing and replacing a weapon. The chapter demonstrates Mana entering the blade, but does not state what else it can absorb, how absorbed power translates into improvements, how quickly growth occurs, or whether there is an upper limit. (Chapter 38)
• Owner Recognition: The second C-level attribute lets the weapon identify an owner. Infused Mana produces a matching resonance, and prolonged testing carries a stated risk that the blade will recognize the tester as its new owner. The source does not define the exact bonding time, whether consent is required, how ownership can be transferred, or whether the weapon rejects other wielders after bonding. (Chapter 38)
• Mana resonance: During the public test, the sword absorbs a judge's Mana cleanly and hums in tune with it. This confirms interaction with an individual Mana signature, but the scene does not show an offensive discharge, automatic technique, or numerical increase in power. (Chapter 38)
• Physical construction: The blade is pure white, sized for both cuts and thrusts, and decorated with the Orc forge's characteristic carvings. Its exact material, dimensions, weight, quality grade, durability, and maintenance needs are not provided. (Chapter 38)
• Attribute source: Sae-Jin credits the horns of Treynos with allowing both attributes to be placed into one weapon. The chapter does not explain whether the horns remain part of the finished broadsword or merely enabled its manufacture. (Chapter 38)
• Demonstrated limits: The supplied evidence covers the tournament demonstration only. It does not show the broadsword in combat, confirm how it changes after bonding with Sae-Jung, or establish whether its growth can repair damage or alter its form.
