@Wolvenworks Straightforward and honest is how Orobas operates according to the Ars Goetia from which most of these characters are based. Orobas only tells truths about the past, present, future, divinities, and regarding the creation of the world. He will never deceive anyone and protects his summoner from being tempted by other spirits. So this series's Orobas family is actually playing that rather straight in claiming they are always sincere and straightfoward, but ironically their powers indirectly revolve around deception through illusion- though there is a logical out to that by them not being in control of what their targets see and is merely pulling out some actual true feeling they are repressing or harboring.
@Shuzuchi Yes literally juice or some similar beverage since Japanese also likes to include sodas and soft drinks under the loanword 'juice' too. Remember Clara was introduced as being a go-for by some mob characters, who were putting up with her nonsense because she could conquer them free stuff. They were basically using her like a vending machine and her hallucinations here are borderline verbatim repeating what they used to say to her in that chapter but now coming out of Iruma's mouth.
