This is an outline for the scenario where the party encounters Shadow Shion.
Shadow Shion: "More guests come to see my performance? Ooh, I'm so flattered!"
Shion: "S-s-stop saying that embarrassing stuff. This isn't funny, Mion. Where did you take me exactly?"
Mion: "Shion!"
Shion turns around.
Shion: "Mion!? Wait, if you're over there, then…"
Mion: "Get away from that thing right now!"
Shadow Shion comes up from behind and starts fondling Shion.
Shadow Shion: "Aw, why do you have to be such a party pooper, big sis? Don't you, of all people, want to see me get naked?"
Mion: "W-what!?"
Shadow Shion: "Were my finger nails not enough for you?"
Mion: *winces*
Keichi: "Let go of her, you freak!"
Rika: "Shion!"
Shion: "I can't…move."
Shadow Shion stops fondling and Shion falls to her knees.
Shadow Shion: "Wow, you really are a pervert. Just a little groping and you're already on your knees? Geez. What did Satoshi ever see in a useless pervert like you?"
Shion: "Don't… Don't mention his name!"
Shadow Shion: "Why not? I'm you, aren't I? I have just as much of a right to him as you do. Tell you what. We'll split him in half. You get his upper half, and I get his… Teehee\~!" *she licks her lips* "Lower… Half."
Keichi: "That's so messed-"
Mion: "Stop, Kei-chan. These are Shion's true thoughts. If we shame her, she'll end up rejecting them."
Shion: "You're me? That's insane!"
Shadow Shion: "Hmph, of course you'd think that. An idiot like you, who couldn't even save the one she loved, wouldn't be able to understand something so simple."
Shion: "Simple! You're not making any sense. And quit calling me dumb! At least I'm not dressed in a revealing bikini, dumbass!"
Shadow Shion: "Aw, but this is the last bit of clothing before I show my true self."
Shion: "Stop! D-don't get naked. Even if you aren't Mion, I wouldn't be able to bear it seeing someone with my face revealing herself in public."
Shadow Shion: "Geez, you're sounding a lot like those stuffy ladies and old farts at St. Lucia! But I know that's not who you really are, you little skank."
Shadow Shion spins around and starts hanging from the pole.
Shadow Shion: "You're someone who loves the limelight. Breaking the rules. Causing chaos and disorder everywhere she's goes. That's all just a ploy for attention. 'Why does big sis Mion get all the love and attention? Why does she get to keep that Keichi boy while I lose Satoshi to that stupid curse!'"
Shion: "Stop it!"
Shadow Shion: "Not that it's much of a loss. I mean, looking at them, they're practically identical." *turns her head to Keichi* "You would make a fine replacement, wouldn't you?"
Keichi: "What, me?"
Mion: "Leave Kei-Chan out of this!"
Shadow Shion: "As overly protective as ever. Not like it matters. Keichi, Satoshi? Anyone would do. Really."
Shion: "What!? I don't think that!"
Shadow Shion: "Of course you do! Why else did you chicken out when Satoshi's life was on the line?"
Shion: "I-"
Shadow Shion: "The truth is that you're out for one person and one person only—yourself! All this rebellious behavior. All this torment you incur on others. It's just to feel that nice rush of dopamine. The drug that distracts you from feeling dead inside."
Shadow Shion keeps spinning and spinning.
Shadow Shion: "This world is truly an unjust place. Demons run amok. People die and get punished for dumb reasons. If I can't beat them, why not at least dance with them? I'll bare it all and show the world the demon it created!"
Shion: "No, stop it. You're not-"
Keichi: "Wait, don't say it!"
Rika: "Looks like we have a fight on our hands."
Shion: "YOU'RE NOT ME!"
