Juri's Links
Juri knows Franco can kill her with kindness & get her to confess everything if he can get her alone. As such she tends to hide behind Noah or drag her own twin sister, Ruri, with her.
Juri being the worse liar of the two Constellation Cats, Franco knows that if he needs to find out what happened, he just has to corner her. She'll almost always come clean about what the 2 sets of twins have been doing all day.
