Ruidio

Biodata

Power Progression

Background

Ruidio is a transmigrator from Earth and an orphan in his new life. After awakening his task system, he spent two years training in Shimotsuki Village, where he sparred with Zoro and developed his physical abilities 2 49.

He went to sea seeking opponents who could help him learn to use his strength. His initial target was Captain Kuro, whose speed technique he hoped to study 2 5.

Appearance

Ruidio has a lean, muscular build with clearly defined, proportionate muscles 9.

• Normal appearance: Black hair and black eyes 31 33.
• Satoru Gojo Mode: His hair turns white and his eyes shine blue 31.

Personality

Ruidio is playful, provocative, and prone to doing as he pleases. He teases his companions and deliberately unsettles opponents, but can also be generous: he gives Nami valuable gold and repeatedly shares food with people he meets 5 11 14 49.

He pursues strength through dangerous experimentation, fighting Kuro barehanded to study his movements and later using his transformation to accelerate training 16 33. His interest in tasks and their rewards coexists with a desire to help others: he returns for young Robin when she desperately chases after her abducted mother, and later says he wants to fulfill his crew’s dreams and reach Laugh Tale 30 49.

Abilities & Skills

Task System

Ruidio’s system finds and manages commissions, awards Essence, and provides information and item functions 2 4.

• Personal Information: Three seconds of physical contact reveals another person’s name and approximate star rating; thirty seconds reveals some abilities and proficiency levels 4.
