[Yumiko meets Mitsuki Tachikawa, and her sister. Maybe the three can be the unit...?]
Yumiko: (Find a unit...)
Yumiko: (How am I meant to find a unit this quick?)
???: "Uhm, excuse me.."
Yumiko: (Oh, it's that girl again.)
Yumiko: (There's more people around now...)
Yumiko: "Me? What is it?"
???: "I saw you at the stand. For the performance festival. I wanted to ask... uhm... can we form a unit together? I want to sign up too, but..."
Yumiko: "Huh? But?"
???: "Me and my sister are both DJs."
Yumiko: "Ah. So I suppose you two aren't working together..?"
???: "No, we aren't..."
Yumiko: "Well then, what's your name? I'm-"
Mitsuki: "You're Yumiko Nagatomi, I've heard that. I'm Mitsuki Tachikawa, but people call me Tsuki sometimes."
Yumiko: "Ah, yeah. Nice to meet you, Mitsuki."
Yumiko: (She seems a bit weird, doesn't she?)
Yumiko: (Definetely not a girl who'd attend Rosarium Girl's School...)
Yumiko: "So, Mitsuki. You're a DJ, right? What's missing from our group?"
Mitsuki: "Someone to illustrate, a VJ. Another singer isn't necessary, but it's nice."
Yumiko: "Got it. Let's find our VJ, then?"
Mitsuki: "Ah, after school, right?"
Yumiko: "Yeah. If you're not comfortable with skipping, that is."
Mitsuki: "S-skipping... I would never..."
???: "Big sister! I've been looking for you all throughout the building!"
Mitsuki: "Huh? Ah, Mio..."
Yumiko: "Ah, this is your sister."
Mio: "Ah, you made a new friend? Awesome!"
Mitsuki: "Ah, uhm..."
Yumiko: "Mio, you want to perform at the festival thing, right?"
Mio: "Yeah! Why?"
Yumiko: "Hm, I wonder how well your effort will be."
Mio: "Eh? Are you challenging me so soon?"
Yumiko: "Not at all. After all, we don't know yet if you're going to get a unit..."
