Leigharch is an Irish driver who spent time with Shenhua. He's a heavy marijuana user—or cocaine user in the manga version—and deals with frequent, poorly-timed hallucinations that tend to kick in during high-stress moments like car chases. His hallucinations are typically pop culture references: stuff like Playboy centerfolds, Star Trek (Picard, Klingons), and classic rock legends like Jimi Hendrix.
According to Shenhua, Leigharch survived a serious overdose that left him psychologically damaged enough to require ongoing medical care. The incident is sometimes described as him being unable to "get back from Mars."
