Jonah ask if he can give him back Malka and shot Yusuf when he asked what was Malka. When Kasper arrived at the base Jonathan was disarmed by Chiquita. Kasper, after learning what happened told that he was going to destroy the base by selling them weapons so a road enabling the transport of troops, oil, and weapons could now run through where the base was, but Jonah did it for him for free. Jonah was locked for days in a shipping container with just enough water to sustain him. When Kasper opened the container he revealed that he had sold weapons to the enemies of his village and was thus indrectly responsible for his parents' death. Hearing this, Jonah tryed to bite Kasper leg, but he was too weak and grief stricken to do anything serious. Jonah asked about the three orphans, Kasper revealed that they were safe and promised to relocate them in Japan, if Jonah offered to take his combat skills and labour as a bodyguard. Jonah had no choice but to accept and Kasper told him that he would work for his sister Koko.
