(POV-Narrator)
After Miharu informed Shin about her travelling for training and attending world tour seminar on monstrology (0A/N: study of monsters), he teleported at the orphanage where she is in. She was shocked to that spectacle. Then, she smiles wryly. Her expression and presence exude a more feminine, pretty and mature charm. Unlike her who once owns a cute and childish charm.
"Shin-onii-chan..."(Miharu)
"Mii-chan, or should I say Miharu? Just in one night you become more prettier."(Shin)
She blushed not only because of compliment but because he noticed her change. That blush charmed Shin further.
(Is she really this pretty? No, that wasn't it. She matured, that is why.)(Shin)
He ask her.
"Mii-chan, you plan to travel for training but... that is not all, isn't it?"(Shin)
He have a tint of loneliness in his eyes. She instantly felt guilt but she hold her feelings down.
(Calm down, Miharu! just hold it in. This is for Shin's sake.)(Miharu)
She never noticed that this time, this very day, she recognized Shin not as her brother but as a man. A man she fell in love with. She steeled herself of the feelings inside her heart of not wanting to part with him.
"Yes, you're right Shin. It is a maiden's secret so I won't tell."(Miharu)
She smiles mischievously. He felt a bit of loneliness but still smile softly. He gave her travelling allowance so she could buy her necessities.
"Also, if you are in a pinch, call my name in the bottom of your heart. I swear to come to you no matter how far."(Shin)
"Thanks, Shin."(Miharu)
"... At least call me Shin-onii-chan for now. And please, don't say, no, promise me that you will not say this is the last time you will cry."(Shin)
She never noticed that tears are falling on her eyes. He hugged her in his embrace so tightly it felt he don't want to let go.
"Smile with me, cry with me, laughed with me. Rin might not be my ideal girl but you're the only person in this world that understands me the most.. We always do it together We understand each other's feelings. Even you were far away, you're always in my heart. So don't you dare to throw away everything, Hero Saintess-chan"(Shin)
"Yes, fufufu... my Saint Hero Deviil King-sama. I love you, Shin"(Miharu)
"I love you, too."(Shin)

"I mean as a man."(Miharu)
"I know. I won't let you go even you said so, Miharu"(Shin)
"You're becoming more of a devil king onii-chan. Fufu, don't worry. When he saved me from that hell, my body, my soul everything was yours. Even if you become the most evil being and world opposes you, I will stand by your side, forever."(Miharu)
"... Don't show that bewitching face of yours to other man. Well leave it to me. In case that time comes, I will protect you."(Shin)
"Ufufu, now you sound like a hero."(Miharu)
"Ahaha."(Shin)
They laughed together and not noticing they are being watched by others.
"Rin-san might be a high spec girl but the most powerful rival is Miharu-san."(Lia)
She muttered with deep admiration. Rin speaks.
"Yes. i might be able to do many things. but in terms of Shin's heart, Mii-chan was able to understands him the most."(Rin)
"If you're the first, she is the second huh."(Yumina)
Rin denied it.
"She should be the one in my stead. That's why I let you all love him so I can rely what I am lack of to you."(Rin)
She explained with bitter smile about Miharu's past before they left.

"You, too, Shin-onii-chan."(Miharu)
I teleported back to the mansion.
"Huh?"(Shin)
"Everyone is on the cellar eating lunch, milord."(Rein)
"Thank you."(Shin)
