Mio Ibuki

Mio Ibuki a student and one of the representatives of class 1-C along with Kakeru Ryūen.

Not only does she possess excellent academic ability, but her physical ability is also not to be underestimated. She is skilled in combat, having the knowledge of several martial skills that can rival those of many martial artists.

Appearance
Mio is a teenage girl of average height with purple eyes and short blue colored hair.

Personality
She prefers acting alone to socializing, which is one of the reasons why she is often isolated in her class.

Unlike her peers, she doesn't seem to enjoy the violence inflicted on others as shown when she flinched after Kakeru Ryūen smashed a glass bottle on the head Daichi Ishizaki or when Albert Yamada was ordered to beat Daichi and the others for their failure in getting Sudō expelled. She made it clear that she couldn't stand nor approve of their cruelty and wanted them to stop their actions.

She doesn't like being insulted as shown when he told off Kakeru for treating her like a plaything when he made advances on her. She appears to not like being pitied as shown when she angrily slapped away the hand of Kiyotaka Ayanokōji despite him trying to help her up after she was knocked to the ground.

Due to her time with Ryūen, she has come to expect mistrust or deception even accusations towards herself. However, she can express surprise when people actually give her benefit of the doubt as she was rather surprised when Kiyotaka trusted her after panties were stolen from the girl's tent. She was so shocked at his belief in her that she nervously blushed while thanking him for it.

She is very deceptive as she infiltrated Class D to steal the key card from Suzune despite the class showing her kindness by taking her in. She showed no remorse in stealing the card even defeating Suzune in a fight.

History
Ibuki is first seen sitting, at the karaoke bar of Keyaki Mall, at a distance of Kakeru Ryūen, where she is seen flinching when he bashes a glass bottle on the head of Daichi Ishizaki.

She is later seen with Kakeru Ryūen and his gang, after he is livid at the failure of his plan to get Ken Sudō expelled. She looks away as Albert Yamada proceeds to beat up Daichi for defying his orders.

During the school cruise, Ibuki goes to confront Kakeru (after he just spoke to Suzune) and demands he stopped his actions but he disregards her words and tells her to come back to his room and puts his arm around her. Disgusted, she slaps away his hand demanding he take her words seriously but is ignored as he walks away. When she tries to stop him, Yamada intervenes as she calls him a puppet for following Kakeru's orders and tries once more to speak to the latter but Yamada pushes her against the rails telling her to stop. Kiyotaka Ayanokōji tries to help her up before she angrily slaps his hand away telling him not to get in her business and storms off.

She is soon found in the forest as the survival test goes on, she has bruises on her face and was slumped against a tree. Mio is taken back to Class D camp by Kiyotaka Ayanokōji, Airi Sakura and Haruki Yamauchi despite protesting that they were enemies as a result.

The morning after the underwear are stolen, Mio approaches Ayanokōji as he is working on the boy's tent. She states she found the theft unforgivable and states she is aware people believe it was her like Ken Sudō who hold mistrust since she's an outsider. Mio stated she knows Ayanokōji holds the same belief but he surprises her by revealing he does trust her, leaving her to nervously thank him and blush.
