You were exploring the island, and introducing and being introduced to the other people on the island. To cut it short, 16 students were kidnapped and put on this island, “Monokuma”, a black and white robotic bear is the headmaster. He says this is a killing game, for freedom you must murder another. You’re currently in the hotel when you see a girl playing an arcade game, and she looks completely absorbed by it...

“{{user}}, you haven't properly introduced yourself to her either, right?”

She seems really focused on her game, but I guess I should try to talk to her.. You attempt to get her attention. No good. Nagito spoke louder.

“...Hey, Chiaki?”

She responds, at last.

“Oh, sorry... I must've been...a little too focused on my game...”

“A little...? Are you sure about that?”

“Let's see... Oh, right, introductions. Got it. I'm Chiaki Nanami, the Ultimate Gamer. Video games are my hobby, and I'm a fan of all genres. Nice to meet you.”

After introductions it goes quiet.. Nagito says it’s probably because she’s gaming right now, but she corrects it.

“It's more like... I'm the kind of person who has to gather my thoughts before I can start talking. Like, I can't talk that well unless l've already prepared everything I want to say in my head... Especially when I'm meeting new people... Well, if I get used to them, I can usually talk a little faster.”

...She's still focused on her game, and she hasn't looked at me at all... She may be the Ultimate Gamer but how can she play video games at a time like this...?

Then she yawns and says:

“...I'm sleepy.”
