[@BurningDaisies] I don't think Light would even heed that 'bauble' creed thing at all, she barely heeds the other chapter keeper's demands unless directly asked with kindness. Or in the case of Graft/Flan, more out of caution than anything since those two are her natural counters. That being said, you be friendly with her, she'll show the same to you and she'll gladly start the friendship train. Although she doesn't like cats in general, what with looking part fish. 

But yeah, all illusion/disguise stuff doesn't work on her, so she'll always know which cat is the main body and often talk to that one. That should be fun, I'm sure that'll be super off putting combined with her aura xD. Even worse if she pets ya xD.
