Personality
Shiori is a very playful and carefree person, as shown throughout her appearances in the manga. She also seems to be a nerd and enjoys analyzing things. She is shown to be very childish, inviting Osamu simply because that'd increase the number of people who wear glasses in Tamakoma Branch, and crying after Jin interrupted her when deciding Chika's position. She is very caring to her teammates, especially Chika. She is dedicated and would go to extreme lengths for them as well, even staying up late to help Yuma with Replica, or report to Osamu in the hospital the distinguished service awards passed out following the Large-Scale Invasion Arc. Shiori is a sociable and energetic person, who is very welcoming whenever they have guests.
