Airi Sakura/Relationships

Kiyotaka Ayanokōji
Airi and Kiyotaka are classmates, but they don't take notice of each other until Ken Sudō's case. They first met when he and Kikyō Kushida went to ask her for help, but she tried to run and broke her camera. Later, he accompanied her to get it fixed and helped her by telling the clerk to send him the notice for the camera instead of her after observing the subtle suspicious actions of the flirtatious store clerk. She then looked at him while blushing, thanking and being greatly appreciative towards him for helping her.

She later asked him about his thoughts on the Sudō's case. When he told her that it's up to her and that the decision she makes shouldn't burden herself, she blushes at his kind words and gazes at him for a while but became flustered when Kikyō returned. Because of his words, she resolved herself to help save Ken and even went to the hearing, willingly presenting vulnerable information about herself to others.

When Manabu Horikita hinted that one side could be lying in the case, Airi got intimidated by him and started fretting. Kiyotaka noticed and quickly intervened by saying that he believed her, much to her relief. After the hearing, she apologized for not working up the courage to help out sooner, but he told her not to worry about it. She was greatly concerned for Kiyotaka when Manabu suddenly tried to attack him.

A day later, she looked intently at Kiyotaka's desk, before he appeared behind her, thus surprising her. He told her to be at ease and stated that if she ever needed him, he'll be there for her. Airi was touched as she blushed and smiled as she tried to ask him something. Although he had to excuse himself, he did promised to hear her out after he was done.

When she was being stalked and assaulted by the store clerk, she quickly phoned Kiyotaka, hoping that he could save her. When he answered the phone, he got confused by her strange tone and tried calling her back. As she was about to be assaulted by the store clerk (who previously made advances on her), Airi reflected on Kiyotaka's promise to help her anytime and tried to reach for her phone once again, but to no avail as the clerk kicked it away. However, Kiyotaka came to her aid in the nick of time by arriving on the scene and catching the man in the act before threatening him with incriminating evidence. When the man tried to flee, he was skilfully ambushed by Honami who had accompanied Kiyotaka along with the police. After the man was taken away, Kiyotaka expressed relief that they had exchanged contact information which allowed him to find her. She apologized for dragging him into such a mess, but he comforted her by saying that the incident was not her fault and that she should enjoy her status of being an idol. Airi then decided to stop hiding her secret and apologizes to him and took off her glasses to embrace her new status.

Kiyotaka offered to give advice in the future for any burden that she may face, before helping her up. She then looked at him, surprise by his words and took his hand. Once on her feet, Airi faced him and blushed, remarking on how the look he gave her, was something that she has never seen him make before. He was confused by her words though she shrugged it off later with a smile. It is most likely at this point that Airi developed romantic feelings for Kiyotaka. It appears that Kiyotaka is initially unaware or indifferent to her romantic affections for him.

During summer break, she accepted his invitation to come to the pool. When most of the students started splashing each other, she did the same to Kiyotaka but was seen to suddenly become nervous when he looked at her, fearing that he may had hated her, this caused her to apologise profusely and sink in the pool in embarrassment.

On the school cruise, when she tried practicing to confess her feelings to Kiyotaka, she was seen blushing as she struggled with her words as a result. She was surprised when Kiyotaka unexpectedly appeared before her. After learning that he didn't hear what she said, she was relieved and instead asks Kiyotaka if he could help her in socializing with their class since she still had problems properly talking with them. He agreed which caused her to become elated, while also grabbing his hand out of gratitude.

During the survival test, she was paired up with Kiyotaka and traveled through the forest with him. When they discovered a spot, Kiyotaka hid her and covered her mouth after she tried to move ahead when Kōhei Katsuragi appeared. While being held tightly by him, Airi was shown blushing a full red and breathing heavily. After the coast was clear, Kiyotaka released her. He apologized for his sudden actions, but she was seen still heavily blushing and squirming on the ground much to his confusion. Later when Suzune refused his offer, he instead asked Airi to come along with him, as they looked for branches to start a campfire. She was extremely happy when he invited her and excited at the prospect of spending some alone time with him.

Airi was also seen talking to Kiyotaka as he asked her if she wanted to stay in a pair with him, to which she confirmed and apologized for being a burden and dragging him down in the search. He soon asked her if she was afraid if people started talking to her about them, as she told him that she didn't really care about that, explaining that she was down on the school trip at first due to not having friends, but now was glad that she came. She then looked him in an admiring way, stating regrettably that she wanted to have her camera so that she could take a great picture of him, hinting that she wanted to keep a photograph of him to fawn over once the test was over.

At the final day of the survival test, she was helping Kiyotaka in cleaning up the campsite, where she asked him how many points that he thought their class were going to get by the end of it. Kiyotaka then wondered about her question causing him to look at Yōsuke Hirata afterwards. Due to his real thoughts, it is unknown what he really thinks of her at the end of the anime, as he still views people as pawns to make him win.

Kikyō Kushida
They don't have much of a relationship, as Airi appears not to trust Kikyō. They did not have much interaction until Episode 4 when Airi was pointed out by Suzune as the only person who did not volunteer to help Kikyō prove Sudō's innocence. Kikyō and Kiyotaka soon go to meet with her, but Airi refuses to get involved and runs off. While so, she ends up accidentally damaging her camera. In Episode 5, she invites Kikyō and Kiyotaka to help her repair it and apologizes for the trouble she's caused them though Kikyō did acknowledge her partial responsibility. They appeared to get along well, but Airi did not open up completely to Kikyō. When Kikyō leaves for a moment, Airi spoke more openly with Kiyotaka. Her reason was that his eyes weren't "scary" indicating her mistrust in Kikyō.

They meet again for summer break while hanging out at the pool Kikyō remarked it was the first time Airi hung out with them asking if she liked pools, but she replies that she came because Kiyotaka invited her.

On the school cruise, while talking to Kiyotaka, Kikyō appears which causes Airi to run off. This meant that she is still wary of her, but the extent is unknown.

Haruki Yamauchi
Haruki is one of her classmates while much interaction has not been shown, they appear to get along. Unknown to Airi, Haruki harboured feelings for her due to both her attractive body and personality which he finds appealing. He even got excited at saying her first name repeatedly and would try to show he was a nice guy by helping out Mio Ibuki. However, Airi doesn't feel the same way about him due to her romantic feelings for Kiyotaka.

Honami Ichinose
There hasn't been much interaction shown between them. They first met in Episode 6 where Honami and Kiyotaka came to Airi's aid when she was attacked by a crazed stalker. Honami was the one who gathered security and eventually apprehended the suspect, saving her from the dreadful situation. During summer break, they hung out at the pool. Honami would tease though in a playful manner of a nervous Airi for her close relationship, and her obvious romantic feelings for Kiyotaka, much to Airi's embarrassment. She then adamantly rejects such a notion and tried to cover it up with an excuse. Their limited interactions thus far shows they are on good terms despite being in different classes.
