[58 Days Before the Awakening]
What Asha didn't know was that Nadia actually had three Domain stage demon puppets. The Angel and Vlad are but the first two, with the third, Maud, being the strongest of them all.
Maud is a level 7 Domain stage Demon Puppet.
Klaus sensed her presence when Vlad appeared, but due to Asha's state of mind at that moment, he chose not to make things more heartbreaking for her.
So instead of allowing Nadia to mess with her some more, Klaus suggested to Nadia through telepathy that she should let Maud remain hidden.
She did, and that was when Klaus came up with the plan to help Asha.
The Underworld Stone Berries aren't something he can easily give out. If one of them were to appear in the universe, many would fight over it.
