We would like to notify everyone regarding the Intensive Training Item acquired from shopping bag or shop. You can only check the owned number of training items after you upgrade your character to Intensive Character. This is due to our system showing training item UI only via skill training page. Please be aware that your purchased/acquired intensive item is stored in your inventory without problem. The developers are currently finding a way to improve the UI to be able to check your owned items without unlocking the content. Rest assured that your acquired items is safe.
Thank you for your continued support and we hope for your understanding.
