Ryuuko's eyes narrowed as the family was described. Old enough to have splintered repeatedly and yet every branch was claiming equal importance... yet owing none of the loyalty to one another that such a description would suggest. To her, someone that placed her family's wishes before anything else, such a self-interested approach to the rest of one's relatives was abhorrent. Well, maybe the Miura's lack of fragmentation helped--for instance, she had no siblings--but to intentionally set out to kill one another as a matter of course...

This wasn't her detective agency, however, and dealing with unsavoury sorts was part of her education. No matter that such a group offended her sensibilities, Ryuuko would stomach them for the sake of their contract. If any information might present itself that might aid her father... well, she'd ask Toshiko when the time came. 

The girl took another drink of the cooling tea, looking once more at her teacher: "If this family cannot trust their kin, I hope that we shall not rely on their hospitality. I will be bringing my sword but there is little I can do against magic."
