Ok since I keep seeing people who don’t know Midari canonically has a girlfriend, I hope this post will help explain.
This girl here is Midari’s girlfriend, her name is Ayame Nureba. She and Midari start dating during the Kakegurui Midari manga (a prequel to the main series that takes place right after Midari joins the student counci. She has had a significant role in Midari’s life, and she is the reason that Midari is currently alive during the events of the main series.
Here is a short list of what she did with Midari, did for Midari, and what Midari did for her:
-Midari saved her from committing suicide and then canceled the debt that led to her that attempt in the first place
-After pulling her off the roof, we see that she and Midari hugged each other for a minute until Ayame calmed down a bit
-They had sex at the beginning of chapter nine, which is something Ayame said she could only do with someone she loves
-Ayame helped Midari get off multiple times during gambles
-Midari threw a party for Ayame and made her a cake after she joined the beautification committee
-Midari loaned Ayame 1.2 billion yen of her own personal money for a gamble and then gave her 300 million yen for winning the gamble with Naoe
-Ayame told Midari during the Kill or Die gamble that she wanted her to live and that she was her savior and was fine with the fact that letting Midari live would mean she would die
-Midari told Ayame that she loved her, and Ayame is the only person that Midari has said this to throughout the series
-Ayame mentions at several points that Midari was “willing to die for her”, and as stated earlier, we see that they would both do anything to keep each other safe from harm
Several other things that aren’t big actions like mentioned above:
-Ayame and Midari are both shown to be very playful and flirty with each other throughout the manga
-Midari is especially touchy and lovey with Ayame, often shown hugging her, having an arm around her shoulder, or holding her hand
-Ayame has tried to take special care of the things Midari values, for example, upon finding her gun in the beautification committee room, she decides that she should try and clean it for her
-Midari nicknamed Ayame “girlie” and calls her “good girl” on multiple occasions
