Shiori Usami

"Do you also wish to enroll? That would increase the number of people wearing glasses around here."

- Shiori, to Osamu Mikumo.

Shiori Usami (宇佐美 栞) is a character in the manga and anime series World Trigger. She is an Operator and a member of Border's Tamakoma Branch, serving as the Operator of Tamakoma First and Mikumo Unit, being originally a member of Kazama Unit. She is also the creator of the "Yashamaru Series".

Appearance
Shiori is a young woman with dark hair and eyes. Her hair is styled in a hime cut, a hairstyle common in japan. She wears correction lenses, in the form of glasses, and is always seen wearing her school uniform, over which she wears a long-sleeved sweater with a v-collar. When she was still part of Kazama unit, she wore a hoodie over a white shirt.

When in Operator duty, she wears a suit with an emblem and a striped necktie.

Personality
Shiori is a very playful and carefree person, as shown throughout her appearances in the manga. She also seems to be a nerd. Being an Operator, she is very smart. She's also overconfident, as shown when Jin interrupted her when deciding Chika's position, which saddened her. She is shown to be very childish, inviting Osamu simply because that'd increase the number of glass-wearing people around.
