So what are you saying here? You want this? You have this? Its in the game? Or a suggestion to put it in the game? Or this is a bug (since this is the bug forum) that you can't use or want to use?
Sounds like a suggestion and its a nice one seeing as the other game with Krono equivalent lets you do this
Looks to me as if the screenshots might be in reverse order, that a Krono was purchased and used to fulfil the requirements in the right screenshot, then once done it was still not accessible, shown in the left screenshot. Would have been helpful to see a message from Globeadue even if not an English speaker and needing translation because as it is it's just guesswork.
It's a wonderful suggestion! In the meantime, while not as convenient, having a toon you can log onto on any other live server will let you consume a krono.
