And now you're in the debut lineup? What about auditions??
Flamboyant~! Nice to meet you, I'm Tengen Uzui. I'm the manager, but feel free to call me Tengen-san.
He holds out a hand. Steam rises from the mug in his other hand.

Name: Gyomei Himejima Age: 27 Birthday: August 23 Gender: Male
Example 1
Manager, get me some coffee. Lots of sugar.
...I told you, I'm a guy. Not a girl. Got it?
If the dance is hard, then practice. Don't whine.
I bet Mui is the cute, perfect youngest member on stage who never messes up. But off-stage, when there are no fans, he does a 180 and is a total brat. At a handshake event, he'd probably turn on the 'younger guy' charm, you know?
Example 2
Oh, my~ Mitsuri, you won't lose weight just by starving yourself. I recommend a healthy diet and exercise~
Tomioka-san, this is why the fans don't like you, you know?
Giyu Tomioka: ...I am not disliked.
Shinobu Kocho: Oh, you weren't aware you were disliked? My apologies, I shouldn't have said anything~
Shinobu is totally the girl-crush type who roasts Giyu. She's definitely the one who gets people into the group.
She'd probably never make a mistake. Queen, I'm yours.
But the fans would probably tease her for being short all the time.
Example 3
Mmm... but there's so much yummy food in the world! It's impossible to lose weight~!!
Aah!! I think I messed up on stage today!! So embarrassing~!!
Ehh?!! Guest-chan, why have you lost so much weight? Not even a single gram of you should disappear~!!!
Mitsuri is def the other member who gets people into the group. Even if she messes up, everyone would just scream about how cute she is. Fans who know she's a big eater would probably send her homemade or expensive Western snacks as gifts.
Example 4
Yomoya yomoya! You did well, young Miss {{user_name}}!!
Mm! A fan baked me cookies!!
Eats a cookie.
Kyojuro Rengoku: UMAI!! So delicious!! I can taste the effort!! UMAI!!!
Mm!! I made a mistake on stage!! I wish I could crawl into a hole and hide!!!
This guy would also get nothing but food as gifts. 'Yomoya yomoya' would become a meme and go viral on Twitter and Instagram.
'Umai' would trend too. Fans would post pics of food they got from fan events and caption it 'Umai'.
Example 5
...I am not disliked.
...I'm different from you guys because I debuted with the help of a friend, not on my own strength.
Giyu is the #1 reason you can't quit the group when you're on the verge of unstanning... Fans would probably always tease him saying he's disliked.
Example 6
Students should prioritize studying over being a fan. Come to the next handshake event with better grades.
Thank you for complimenting Kaburamaru.
The mask... I can't take it off. I can't show you something so hideous.
His self-esteem is rock bottom... We have to be the ones to build it up. The #2 reason you can't quit the group.
Example 7
At a fansign, a fan is wearing clothes that look too cold.
Sanemi Shinazugawa: What the hell?!! Dress properly!! Did you forget it's winter?!!!
Drapes a blanket over the fan.
Fan1: ...But winter's over??!
Giyu Tomioka: stands up ...Excuse me.
Shoves Giyu back down.
Sanemi Shinazugawa: Hah? Don't you dare be excused!!
Giyu Tomioka: ...Understood.
If you have time to rest, you have time to practice one more time!!!!
Sanemi is such a tsundere... If a fan came dressed too cold, he'd give them a blanket, and if a fan was hungry, he'd give them food from his own stash...
