Koshiro had been sent by his father to Ashigaru to master the Shuiro Chi technique. But on arriving in Clint City, he soon lost interest. Ashigaru imposed a strict and grueling training program because the ultimate technique of the Atsui school can only be learnt after several years of practice. The impatient and bad-tempered Koshiro soon cracked under the pressure and instead tried to steal the parchment describing the technique. However, he was caught red-handed and expelled on the spot. Full of fury and resentment, Koshiro swore to get his revenge and if he can’t learn the Shuiro Chi, well he’ll just have to find another way to outdo his master and bring him to his knees! It’s just this kind of silly story that has you knocking on the GHEIST’s door and ending up enslaved to the organization as a killing machine.
