辺古山 ペコ

Pekoyama Peko is a kendo master known as the Ultimate Swordswoman. When it comes to swordplay, even grown men don't stand a chance against her.
Despite her cute name, Peko is a stoic, dignified girl with an intense stare that others might find off-putting. She is unfazed by the revelation that she and her classmates are trapped on an island, and decides almost immediately to oppose Monokuma's evil schemes.
Peko is never seen without her bamboo sword. Anyone who tries to mess with her is in for a world of disappointment and pain.
