No. [She has other servants, but this fake shouldn't have access to them. However, it may be a good idea to brief him about her so he'll stand a chance against the fake.] As a Goddess, hers are the domains of Love, Fertility, War and the Heavens. If this sounds like a lot, this is because Ishtar is a spoiled child who took authorities from other gods as she pleased. She even tried stealing mine once...

[ ... The glorious story of how Ishtar failed and was brutally murdered by her own sister. But that's embarrassing to speak about, so she won't mention it. She doesn't want Kazuki to get the wrong idea and think she's violent, her killing Ishtar was 100% self-defense!! Well, 90% self-defense and 10% resentment. Okay, 50% self-defense, 30% resentment and 20% jealousy. Okay, maybe only 30% self-defense...

... ... ... ... ... ... ... ... ...

A-Anyway! ]

She may ask you to worship her and give yourself to her, only to brutally kill you if you refuse. [Is she exaggerating? There is no saying.] If you have a jewel, jewelry, precious metal and the likes, this may distract her for a moment. D-Do not speak my name however! If you do, she will get defensive and defame me with the most horrible words known to man...!

[ Clearly a healthy and good relationship between two very normal sisters. ]
