Leilong

Shimi, whose real name is Leilong, is the first assassin sent after Gene. He carries an immense backpack around with him, which is full of an assortment of weapons, including a sword, pistol, rockets, and a top of the line Space Forces light shield. He is a very skilled duelist and is yet to be defeated. During their duel, he easily defeats Gene. After witnessing this, Jim, Aisha, and Suzuka attack, intent on vengeance, but are also thoroughly defeated. Surviving with a wound to his ribs, Gene is then challenged to a one-shot duel by Shimi. Gene wins the duel due to Shimi having a faulty gun. Believed to be dead, he is buried by Gene and the others, but eventually digs himself out of his grave muttering: "They sure buried me deep enough." Instead of continuing his life as an assassin, Shimi chooses to start his life anew as a wandering outlaw, having orchestrated his defeat and "death" for the exact purpose of removing himself from the Kei Pirates. A prior conversation with Gene portrays his lack of enthusiasm for killing. Although he is first to be defeated, he is suggested to be second only to Hazanko in strength.
