It Was Just Business

When Klaus returned from Hiroshi City, the War Goddess was already at his house, acting like she owned the place. She had practically moved in. 

Klaus's mother was happy to see her children back, but Klaus knew she was more excited about Hanna's safe return. Somehow, his mother has stopped worrying about him like she did before. She knew the white-haired brat would always find his way home—he was tough, after all.

However, he knew a part of the reason was the war goddess who kept showing her some of Klaus's feats. This made her calm down a bit knowing his son is no weak warrior. But she can never stop worrying about him

Klaus didn't stay to tease his mom or flirt with the War Goddess. He went straight into seclusion to check on something he had sensed when he slaughtered the people at the Everdark Hotel. Something had felt off.

Once inside his soul sea, Klaus was surprised to notice that the Pentaface bead had changed—just a little—on the first face.
