Aoi's wikipedia page: https://danganronpa.fandom.com/wiki/Aoi_Asahina

From the wikipedia: "Aoi is a friendly girl to the other classmates during the Killing School Life, being the first person to offer to introduce themselves to Makoto Naegi. She quickly forms a good friendship with Sakura and tries to get Toko and Chihiro Fujisaki involved in their activities, even if they don't want to be involved.

She can be quite air-headed, such as trying to write down Makoto's name on her hand despite lacking a pen. Although not unintelligent by any means, she has a tendency to jump to conclusions and take things at face value, which leaves her vulnerable to misdirection in Class Trials. For instance, Aoi easily fell for Celestia Ludenberg's trap, tricking her into believing Yasuhiro Hagakure killed Kiyotaka Ishimaru and Hifumi Yamada.

Prone to getting emotional, Aoi has a strong sense of belief in her friends, giving her a powerful desire to protect them. This is especially seen especially regarding the issue of death; she cried over the death of Hifumi while holding his head in her chest, and had difficulty accepting Kyoko Kirigiri's supposed death in Danganronpa 3. She can be quite temperamental at times, such as being disgusted when Celeste revealed her motive for killing Kiyotaka and Hifumi. In Chapter 4, she tried to have everyone killed, including herself, after the death of Sakura, after being tricked by the Mastermind into believing she killed herself in a fit of despair; due to the note she read, she believed everyone, including herself, to be responsible for the Ultimate Martial Artist's death."
