One of the Four Beauties of Ancient China. Having been saved by Wang Yun when she was an orphan, she uses her natural talent to lure his enemies into her snare. From "Romance of the Three Kingdoms." 
Real Beauty
Ichie (Diaochan):
"Please protect me, Dong Zhuo! Lu Bu is so violent. I'm afraid for my life..."
Ichie:Hmm... This is not quite right.
Ichie:(I'm not sure how, but I can just imagine Fumi telling me my performance lacks a punch...)
Ichie:(Maybe it's because the original story used tons of difficult words...? I feel that I don't quite get who Diaochan was.)
Ichie:Hmm... Time to go to the library, I guess! There should be easier versions of Romance of the Three Kingdoms!
Ichie:Off to the library, Ichie!
Ichie:923...923... Chinese literature...
Yuyuko:Huh? Ichie-san?
Ichie:"Oh, if it isn't my dear Wang Yun!"
Yuyuko:Did hell freeze over? It's unusual to see you here.
Ichie:Did you completely ignore my passionate line!? Wang Yun is Diaochan's father!
Yuyuko:It's against my principles to act outside a play...
Yuyuko:Anyway, are you looking for something in particular?
Ichie:Yes — something on Diaochan!
Ichie:I know that Rinmeikan has quite the collection, but I was looking for something different.
Yuyuko:I see. Most of the books in Rinmeikan are quite old indeed.
Ichie:Ah! How about a "Romance of the Three Kingdoms for Dummies"? Or you could give me a lecture on it...? Pretty please!
Yuyuko:*sigh* Fans of the book won't be too happy about your approach.
Ichie:Sorry, sorry! Help me out, please!
Yuyuko:All right then... Mind you — it's not my forte so don't expect too much.
Ichie:Thank you, Yuyuko! I'll buy you a tomato juice next time!
Yuyuko:Heh heh. Looking forward to that. Anyway, you already know the overall story, right?
Ichie:It's about the Three Kingdoms in China — Wei, Wu and Shu!
Ichie:It starts with the Yellow Turban Rebellion and ends with the fall of Wu!
Yuyuko:Exactly. Diaochan was born and lived through that period of great turmoil.
Yuyuko:She came to be known as a dangerous woman as she used her allure to lead Dong Zhuo to his death, but...
Yuyuko:She was also renowned for her loyalty to Wang Yun and Lu Bu.
Ichie:Oh, you're right!
Ichie:Diaochan could have used her charm to side with anyone, but she decided to use her good-looks and side with Wang Yun and Lu Bu.
Yuyuko:She sounds like you in a way.
Ichie:Heh Heh. I may be a charming young woman unrivalled through the whole land, but—
Yuyuko:You don't pull any pranks on anyone other than us.
Ichie:Huh!?
Yuyuko:Anyway... What I was trying to say is that she doesn't go around recklessly using her power.
Yuyuko:How about it? Do you feel more confident about her now?
Ichie:Oh, yeah. I was too caught up in the dangerous aspect of her portrayal.
Ichie:That's why I was focusing on her charm, rather than the fact that she was loyal and hard-working.
Yuyuko:Heh heh. Her beauty managed to fool someone like you, too.
Yuyuko:That's probably how Dong Zhuo and Lu Bu also fell victim.
Ichie:Ngh... She really did! Next time I won't be fooled so easily!
Yuyuko:I'm sure you won't. How do you plan to change how you perform Diaochan?
Ichie:First and foremost, I'm going to change my attitude depending on who I'm interacting with!
Ichie:I'll act like a charming beauty in front of Dong Zhuo, and like a loyal person in front of Wang Yun!
Yuyuko:That sounds exactly like something she would do. I'm looking forward to seeing it in action next time.
Ichie:Don't you worry! My Diaochan will blow your mind!
Ichie:All right then! I'm gonna go practice now! Thank you for everything, Yuyuko!
Yuyuko:Heh heh... I better polish my Wang Yun, too.
Loyalty and Charm
Ichie (Diaochan):
"Sigh... If I were the Moon, I could shine over you during your darkest hours..."
Yuyuko (Wang Yun):
"Diaochan..."
Ichie (Diaochan):
"Oh my. Father..."
Yuyuko (Wang Yun):
"You look as beautiful as always. What is troubling you?"
Ichie (Diaochan):
"Nothing... I'm just sad."
Ichie (Diaochan):
"You have no use for me, Father. I'm no more than a doll..."
Yuyuko (Wang Yun):
"Nonsense. Having you by my side gives me peace of mind."
Ichie (Diaochan):
"Still... Peace of mind won't help you defeat Dong Zhuo."
Yuyuko (Wang Yun):
"You heard me..."
Ichie (Diaochan):
"Yes, I heard you saying Dong Zhuo is still too powerful. I wish I could offer some help, but alas I'm too powerless."
Yuyuko (Wang Yun):
"Aah... It has come to this..."
Ichie (Diaochan):
"Father?"
Yuyuko (Wang Yun):
"Even if it means knowing that you'll lose yourself in your grief and become but a mirage of yourself..."
Yuyuko (Wang Yun):
"Even if it means knowing that you'll disappear from my eyes... I'll tell you my plan."
Ichie (Diaochan):
"I'll do anything I can to help you! I'm prepared to disappear!"
Yuyuko (Wang Yun):
"...Listen. This plan depends on your melancholic beauty."
Yuyuko:That was great, Ichie-san.
Ichie:Heh heh! I practiced a ton!
Yuyuko:You can perform a beautiful role when you don't have too many lines.
Ichie:First you compliment me, and then you diss me!? Anyway, I'd rather be cute!
Yuyuko:Oh, okay. A marvelous actress gifted with cuteness — that's you Ichie-san.
Ichie:All thanks to your advice! I haven't forgotten about the tomato juice by the way!
Yuyuko:Sure... Huh?
Ichie:What is it?
Yuyuko:Did you hear something just now?
Ichie:You're right...
Ichie:...Haah! I recognize this walk — Lu Bu!
Fumi:Ichie! What did you do to the script!?
Ichie:"Oh my. Have you read my love letter?"
Fumi:Why did you write all around the margins, though!? That's just a simple prank, it is!
Ichie:"How could you call it a prank...!?"
Ichie:"I even went to great lengths and wrote it in pencil too. If you find it offensive, feel free to erase it!"
Fumi:You plan to reply as Diaochan forever? Erasing it is not the problem.
Ichie:"I know what you're trying to say."
Ichie:"Erasing it would mean that you disregard my feelings...which you don't want to do."
Fumi:I haven't said anything of the sort!
Ichie:"I knew it. You love me!"
Fumi:Accepting your prank doesn't mean I love you. Erase it yourself!
Ichie:"Lu Bu — you're so mean. You don't love me then!"
Ichie:"Oh, poor me! I may as well disappear like a mirage — Farewell, everyone!"
Fumi:ICHIE! Come back here, you sly fox!
Fumi:ICHIEEEEEEEEE!
Ichie:"Heh heh! Catch me if you can, dear Lu Bu!"
Yuyuko:Look at that. Diaochan is toying with Lu Bu's anger... Ichie really is good.
Ichie:I heard that Diaochan was a "dangerous woman", but I thought it meant that she gets scolded often! Huh? That's just how Fumi reacts to her?
Ichie:When I got the role of Diaochan, I thought that she was completely different than me, but Yuyuko made me realize we're not so different.
Ichie:I should have realized it myself. Diaochan cares about those around her, and she's an excellent prankster too, after all...!
Ichie:And more importantly, we're both real beauties! Tee hee!
