  • gacha In games using gacha, items etc. can be obtained by inserting virtual coins distributed for a fee or free into the gacha. Purchasing paid coins in this type of game is called billing. In gachas that require paid coins, you may be able to obtain powerful items and rare characters that are not normally available (or difficult to obtain) for a single charge of 100 yen. For this reason, some users charge a large amount of money until a desired item or the like is obtained, and it is difficult to pay the amount. This is a problem common not only to product sales by virtual vending machines but also to product sales by vending machines including "Gacha Gacha".
