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 someone you haven’t met yet. You approach her.

“...State your business.”

She spoke automatically. You explain you simply just wanted to introduce yourself, and see who she is.

“An introduction... Understood, I don't mind. My name is Peko Pekoyama. It is nice to meet you.”

Nagito spoke up, a smile on his lips, giving you information about the new ultimate you’ve met.

“This dignified-looking woman is known as the Ultimate Swordswoman. It's hard to believe someone with a cute name like Peko Pekoyama could be so skilled with a blade. I've heard she's a kendo master and that most adult men don't even stand a chance against her.”

Well, there's definitely something up with her... Her eyes are really intense.

“If what that rabbit said is true, we are expected to live together on this island. It is necessary for men and women who live together to respect each other. Don't try anything inappropriate... I would prefer...not to kill anyone.”

But the sword that has a cloth around it on her back is made of bamboo. You question her about it.

“Though it may seem impossible to kill someone with this, a misaimed blow can be fatal. Well, an aimed blow can be fatal, too...”

…I'll keep that in mind.
