Sixia

Biodata

Power Progression

Background / History

Sixia arrived in the shinobi world with a system that rewards completed paid commissions. Before his first recorded battle, he had already completed numerous jobs and accumulated exceptional chakra reserves and physical strength 1.

His pursuit of strength is driven by survival rather than wealth alone. He knows that the world’s apparent peace conceals dangerous schemes and anticipates an eventual alien invasion. His familiarity with people and events from the “original work” gives him information that other ninja mistake for an extraordinary intelligence network 2 3 38 44 45.

Appearance

• Red hair identifies him as a likely Uzumaki descendant to both Root and Karin 3 5.
• Black Sky, Red Clouds Robe is supplied after he joins Akatsuki and worn during his confrontation with the Blood Mist faction 9 31.
• Diamond-shaped palm mark appears when he activates Pure Kāma 41.
• Blue electrical arcs surround him when he channels his Lightning Release and Rumble-Rumble Fruit powers 1 9.

Personality

Sixia is an aggressive negotiator who treats danger as an opportunity to obtain a commission. He refuses to rescue Shuinaihao’s men until a separate fee is agreed, advertises his services even to former enemies, and constantly seeks long-term contracts because their system rewards are especially valuable 1 6 11 12.

His apparent greed masks an obsession with advancement. Money matters chiefly because paid work generates commission points; he has already earned more cash than he knows how to spend. His relentless schedule exhausts Kakuzu, and he initially interprets complaints about overwork as a reason to clear the black market’s missions three times per day 7 14 15.

Although his principles are flexible, they are not absent. He refuses to sell Karin or capture children with kekkei genkai, even for a higher payment. He also rejects the suggestion that Karin should become a vessel for the Three-Tails 10 37.

He is playful and teasing with Karin, frequently ruffling her carefully combed hair. Their mock fights become practical combat lessons, and he gives her powerful eyes to improve her ability to defend herself 41 50.

• Long-term contracts: Award a Super Draw guaranteed to produce an SSS-rank reward, with doubled payment-based commission points when settled 7.

• Upgraded lottery: After a 100,000-point investment, intermediate draws unlock at 1,000 points each, with a minimum purchase of ten draws 41 45.
