Ryūichi Naruhodō spent his early years as an only child in a modest public housing complex, his ordinary upbringing marked by a defining fourth-grade incident. Falsely accused of stealing Miles Edgeworth’s lunch money, he was defended by Edgeworth and Larry Butz, whose emphasis on evidence absence shaped his future worldview.

He first pursued Shakespearean acting at Ivy University, adopting theatrical mannerisms, until a newspaper exposé on Edgeworth’s ruthless prosecutorial tactics redirected his ambitions. Determined to challenge Edgeworth’s moral decay in court, he switched to law—only to face false murder charges himself during studies. Mia Fey’s defense exposed his girlfriend Dahlia Hawthorne as the true killer, galvanizing his resolve to train under Fey as a defense attorney.

Following Fey’s tragic death, he inherited her practice, rebranding it Wright & Co. Law Office with Maya Fey as his assistant. Early career triumphs saw him dismantle contradictions in high-profile cases: absolving Larry Butz of theft, clearing actor Will Powers of murder, and defending Edgeworth against Manfred von Karma’s frame-up. These victories cemented his knack for overturning dire odds.

A seven-year disbarment for unwittingly submitting forged evidence forced reinvention. Adopting Trucy Enigmar, he juggled roles as a pianist, undefeated poker pro, and talent agency operator. His poker-honed ability to decipher opponents’ tells later informed courtroom strategies. A murder trial defended by protégé Apollo Justice not only cleared his name but exposed systemic legal corruption, paving his reinstatement.

Returning to law, he balanced client defense with mentoring Apollo and Athena Cykes, integrating psychological tools like "Psyche-Locks" to unveil hidden truths. Later, he partnered with Maya Fey to reform the Kingdom of Khura’in’s unjust legal framework.

Known for unwavering loyalty and truth-seeking pragmatism, he economized with outdated tech and public transit. His theatrical flair from acting days persisted in courtroom gestures and rhetoric. Once-adversarial ties with Edgeworth matured into mutual respect, anchored in shared childhood bonds and justice-driven ideals.

Unbeknownst to him, ancestral ties link him to Ryunosuke Naruhodo, a Meiji-era advocate who defended clients in British courts—a lineage echoing generational legal dedication, though explicit family connections remain unrecorded.
