Debut: Episode 391

The Bon Chari shop salesman at Sabaody Archipelago lends a person a Bon Chari for 500 or sells them for 10,000. For traveling visitors, it is wise to rent a Bon Chari, because if they were to buy one and take it with them on their travels, the vehicle will not work beyond the Sabaody Archipelago.
