Following his recent comeback, Sendo holds a record of 21-2-0, with 20 KOs and is the former JBC Featherweight Champion. After several victories over highly ranked Mexican opposition, he becomes known as a 'Mexican Killer'. Sendou is ranked 5th by the WBA and declared his ambition to defeat the WBA champion, Ricardo Martinez albeit not before indirectly threatening Ippo's most recent opponent (and the boxer who handed the latter his second loss) Alfredo Gonzales, instructing his most recent knockout victim to inform Gonzales that he'll 'see him real soon.' Recently, George Morikawa released a 48-page one-shot manga focusing on Sendo before his time as a fighter. Sendo is based on legendary heavyweight world champion Rocky Marciano, whom Sendo admits he admires most, for his fearless style and passion for infighting.
