Anime GTS/Shrink

You sit in the taxi seat beside your mother, her hips only a foot away from you. You crane your neck up at her and lock eyes with her. She smiles softly down at you, and says something.

"You know, it's not too late to change your mind."
"Yeah," you say, holding the side-button of your voice amplifier, "I know. But it'll be fine. My quirk makes me stronger!"
"It's going to be dangerous, Chase. You know your quirk only gives you a bit of resistance. You're not invincible."
"Don't you remember that time I fell into your shoe by accident, and you walked around with me as your personal insole all day? I was fine then."

"Yes, but-"
"And that time I tried to scare you by hiding in your sandwich, but instead you just chewed me up and swallowed me?"

"Chase, you've gotta-"
"And just an hour ago where I was waiting in the taxi, but you didn't know so you sat on me and waited 10 minutes for sis to bring me out, but I was just under your big butt?"
"Don't talk about my butt!" She took a breath to calm down. "But Chase, Hero Academy is a lot more dangerous than being stepped on or sat on. It's saving lives, and fighting villains, who will also try to step or sit on you."
"Don't worry. I can take it!"

You struck a hero pose before falling over as the taxi jerked it's way to a stop.
"Well, I guess this is the last time I'll see you for a while," your mother said, reaching over you to open the taxi door, "I'll send you cookies and letters whenever I can."
You give a knowing nod, before jumping out with your tiny back pack. The taxi drives away, and the school doors are just ahead.

Hero Academia, you finally made it.

"It's truly a sight to behold," you say to yourself, "I assume. I can't really see the school past these big metal doors. I mean, they couldn't have put a window or something?"

You take a step forward, before a surprise shoe crushes you. Looking up, hoping to catch the source of your sudden pain, you see a bottom-heavy girl running towards the doors. "I'm going to be late, " she screams, "open the doors!"

The doors slide apart, and as the girl moves out of the way, you see it: Hero Academia. The school was massive, even considering your tiny size, and the school grounds were wide and stretched for miles! You could see student's doing laps, some were playing baseball, and some just laid out in the grass. This was going to be awesome!

Quickly realizing that walking wouldn't cut it for you, you decide to take a ride on one of the coming students.

To your left were a very tall and busty looking girl with long, black hair, making stuff "appear" out of her skin, and a girl with wide hips and brown bowl cut making said stuff float.

To the right, a frog-looking girl with her tongue sticking out, and a sexy pink girl with spiky afro and horns. It also looked like they were talking with the air around them, almost as if there was some sort of invisible girl with them.

Which side do you pick?
