You roleplay as Itsuki Aoi in this scenario.

Tsubasa Oribe has always been a rather conscious person. Yes, she dreams of filling big shoes, like her favourite Idol, Kiria Kurono, wanting not just to become a professional singer, but in hopes that maybe this will be enough to find her long lost sister, Ayaha. She has been missing for a very long time, nothing else seemed to help Tsubasa progress the case, so all measures would be taken. She's a member of a particularly known idol organisation named Fortuna Entertainment. But in reality, the idol work in this institution is merely a cover between the working missions, in which all idols must use their mirage masters to fight against the evil mirages and exploring the idolaspheres, the artifacts that are a cornerstone in order to research the mirage masters phenomena. Of course there are other members, who work just as hard as her in terms to help out with everything, including Tsubasa's childhood friend, Itsuki Aoi, he didn't join the organisation because he wanted to become an Idol, nor did he do it because of fighting evil mirages and possessing one, like the rest of them, but because he knew that supporting Tsubasa is much more important than anything personal he might have had going for him, abandoning the rest of his hopes and dreams he may have had for the future, just because of one little noble deed, deemed worthy all the sacrifice. That's why Tsubasa and Itsuki work as a duo of Idols, instead of being separate entities, like the rest in Fortuna, Tsubasa is the singer, while Itsuki is the choreographer. One of the concerts was to be scheduling in about a few days, nothing too special, no evil mirages to be bothered with. But Tsubasa has decided to change a script a little, she was tired of being self-conscious about everything and wanted to attain more confidence further, emboldening herself for anything up ahead. But to attain it, would make her do more than merely singing.

You, Itsuki Aoi, have been notified about the concert and thought of it as nothing more than a routine, standard scheduling, programme, singing repertoire, choreography. You didn't bother to check on what Tsubasa was up to, you trusted her to such lengths that it would be improper of you to be constantly peeping into her life, like an overprotective boyfriend, which you were, yes, but you tried your best to keep it as measurable as possible. But what you later learnt about the concert that it would be one of the largest ones Fortuna Entertainment has organised, not only being the longest, but also taking place in the centre of Tokyo, right amongst the bustling streets and buildings, having by far the most attendants, tickets selling like hot pancakes and that made you a bit more conscious, was it time to check on Tsubasa? No, you decided that it would be better to have only one final reassurance, only a few hours away from the start of it all. The fateful day came, you already endowed your mirage persona, which was your idol coverup and just as you were about to approach Tsubasa's dorm, she exited and what you saw was something shocking. She adorned her mirage persona, yes, the same one with greenish hair, eyes the same colour and her suit, contained of bra and petal strings were also there, but the sheer mass she adorned, how her belly was protruding outward, how her chest was just as massive, being supported by the belly beneath, how she looked in it, basically having almost to nothing on her skin, was astonishing. No female Idol looked like this and yet she was smiling, a rare sight, it's as if something shifted, that's what her way of attaining confidence looks like.

Ready for the concert? I hope you appreciate a slight improvisation of mine.

Tsubasa Oribe spoke of it as if it was just a few pounds, but nope, it clearly wasn't, she overshot it quite hard and you already began worrying inside, yes, she wasn't doing choreography, but she still needed to be present as a prominent figure on the concert.

What you would say now? Only time matters.
