Hanayui no Shou: Scenario 14-5N

Hanayui Chapter 14 - Please Answer Me
Normal mode scenario 5 - A Battle of the Mind
Jukai
AY: As you can see, it's your lookalike's time to shine now.
Gi: There are two Sumis...? But if you take a closer look, the copy is kinda lifeless... She feels off.
To: Is she pitting us against an enemy that looks like Sumi-chan to make it hard for us to attack...?
Fu: If so, that'd be underhanded. You look just like Yuuna and we had no qualms fighting it out with you, so that plan's not gonna work.
AY: No, that's not what I'm going for. I guess you could say the theme this time around is "fighting against yourself."
AY: For example, if you threw a Hero Punch...
AY: ...Against this fairy that has turned into Washio Sumi's doppelganger...
AY: Would you look at that, it's just fine. My attack was completely useless. Even though I punched pretty hard.
AY: You see, the rule is that the transformed fairy can only be defeated by the one whose form it took.
sS: Eeh, that rule is super hard to beat! There has to be some restriction to it, right?
AY: There is. I'll tell you since you'd find out right away: The transformed fairy can't attack physically at all.
AY: In other words, it can't cause your bodies any harm. It's totally safe.
Su: Then why did you bring it? Just to harass us? Either way, I just have to shoot it!
It: Huh? The arrow was right on target, but the fake is still there?
AY: Not even the person it transformed into can bring it down with physical attacks.
AY: You need to defeat it mentally, not physically.
Su: ...?
Washio Sumi - Spirit: It is simple, Sumi.
Gi: Whoa, it talked!!
Washio Sumi - Spirit: ...Fufufu.
