Nanamine Sakura/Relationships

Background
Sakura is a third-year high school student attending Kamome Academy. She is part of the Broadcasting Club alongside Natsuhiko, and spread rumors of the supernatural to the student body. Not much is known currently of Sakura. She appears to be aloof and introverted, often seen with a book in her hand. Through unknown circumstances, she formed a contract with Tsukasa in exchange for a favor... at a price. Now bound to the supernatural, she has to perform his orders even when she doesn't agree with them personally. She's grown to tolerate his existence (thinking of him as a cat) and works surprisingly well with the rest of her club, despite the frequent bickering between the members.

Yugi Tsukasa
Sakura made a contract with Tsukasa and has become bound to him; similar to Nene with Hanako. She treats him like a child, and becomes exasperated if he does anything unnecessarily cruel. Despite this, she cannot disobey his wishes and still aids him in altering the supernatural's rumors. She acts as his assistant, broadcasting his altered rumors to the student body. When conversing with Nene about him, Sakura says that Tsukasa never listens to her, his actions makes no sense, and he has no sense of personal space.

Sakura then says that there is nothing she can do about it, and that she decided to think of him more as a cat than a person.

Tsukasa seems to hold some respect for Sakura and will alter his actions to a certain degree once reprimanded by her.

Hyuuga Natsuhiko
Natsuhiko has a seemingly unrequited crush on Sakura. He often indicates his crush, and thinks that her less than kind actions towards him - like trapping him along with Nene - are simply her way of showing affection. She seems to tolerate Natsuhiko, but she also doesn't seem to have any particular affection for him, and often rebuffs his attempts at romance. She often finds him annoying.

Mitsuba Sousuke
Sakura seems to like Mitsuba well enough, and may actually enjoy his company a bit more than Natsuhiko and Tsukasa. She is briefly seen offering him tea and sympathizing with him after he returns from his boundary. She assists in the party for welcoming Mitsuba to the broadcasting club.

Yashiro Nene
Sakura and Nene are both contracted to supernaturals, and as such have some common ground. The two discuss their supernatural predicament over tea, and while Nene initially doesn't want to talk to Sakura, the older girl is able to get her to open up very quickly. Nene enjoyed Sakura's company, and Sakura seemed to enjoy talking to Nene as well. It is possible that Sakura legitimately desires Nene's friendship, but cannot get too close to the other girl because of Tsukasa. One of the only times Sakura expresses emotion is when Tsukasa has her betray Nene, to which she briefly expresses a look of disappointment or worry.

After Sakura's betrayal, Nene is shocked, and likely develops a distaste for Sakura, although Sakura does not seem to have any ill feelings towards Nene.

Eventually they meet again as Nene is looking for Sumire. The boundary collapses as Sakura grabs Nene. Sakura comforts Nene that she wont be losing her life in the Boundary. Nene realises she’s Tsukasa’s assistant. Nene has doubts on Sakura but feels like she could trust her since Tsukasa isn’t around. Sakura seems to treat Nene well and was genuinely concerned when Nene thought it was her fault that Sumire had to die since she couldn’t peel off the sticker.
