When Gaira wins the first round of a match, he throws a few punches and says 'Tenchu!', which means 'retribution!'. Gaira says a traditional Buddhist prayer for his fallen opponent when he wins the final round of the match. 'Namu amida butsu', Gaira's prayer, is basically 'go to heaven' or 'rest in peace'.
