Alfins an absolute unit quest with new character

Dont get the units when you accept the order, and can't buy the units

Is there any way to comple it

@KtwnKamikazi Most COs that give an item reward only give them once per account. You can use any Units to complete the CO, so if you don't have any in your shared storage, you can check the NPC who sells units in the Shopping area for some cheap ones to use.
