Ayadari

Canon
Midari and Ayame first meet when Ayame is considering suicide on the school rooftop, after losing in a gamble and going into debt. Ayame knew that if she continued living, she would be forced into prostitution. This caused Ayame to go to the school rooftop to kill herself. However, Ayame is stopped and saved by Midari, who was also on the roof.

Later, Ayame participates in another gamble with Nana Ootori, in order to make an attempt at fixing her debt to avoid having to sleep with strangers. It is discovered that Nana is cheating, and Midari steps in. Midari proposes a hand knife trick game for the two to play. They need to stab in between Midari's finger as much as possible within a minute. Nana begins and is rather quick and does not hurt Midari. Next, however, because she is so nervous and scared, Ayame accidentally stabs Midari's finger. Nana is pleased, thinking she just got into more trouble for injuring the leader of the Beautification Council, but Midari orders her to continue and stop being such a coward or finally kill herself. Ayame gets angry at her and decides that now she wants to kill her. She proceeds to angrily stab between her fingers. Although she pierces Midari's hand, she continues. Through all the pain, Midari gets infatuated with Ayame.

Ayame stabs faster and faster, with a wicked smile on her face, as she loses her grip on sanity. One minute is over and she won by a lot. Her debt is now gone and Midari asks her to join the Beautification Council, since it looked like she had fun. Ayame is embarrassed and doesn't know what to say, while Nana panics.

The two end up hooking up inside of a school bathroom, where Ayame asks Midari to be gentle since it's her first time. This is an act Ayame states she would only do with someone she really loves. Midari once again asks Ayame to join the Beautification Council.

Ayame cannot decide whether or not to join the Beautification Council. Eventually she agrees to join, and they go to the council room, where they meet Naoe Habakiri, the vice president of the Beautification Council. Ayame is still upset that she had actually enjoyed stabbing Midari. Naoe rejects Ayame, and Midari proposes the idea that they gamble on whether or not Ayame joins. Naoe agrees, but says that Ayame must leave if she loses. Ayame eventually recognizes that Naoe is tricking her during the gamble, and ends up winning.

After a while, Midari says she has to complete a task and asks Ayame to join her. She explains her duties, saying her job is to deal with the trash in the school and make it pretty again. That day, she was asked to collect money from the leader of a group that is causing problems around the school, Kurimu Terasumi.

The two girls end up gambling with Kurimu in a very dangerous game of Russian Roulette. During the gamble, Midari makes Ayame point the gun at her head. Ayame shoots several times, but nothing happens.

When the gamble is over, the two leave. While walking, Midari asks Ayame if she was actually ready to kill her. Ayame replies that she wasn't because she's still a student and could not live the rest of her life knowing she killed Midari. Midari smiles, pleased with Ayame's insane side; then affectionately hugs her and says she loves her, which makes Ayame flustered.

It is then revealed that they would both die to protect each other and there is no limit to how far they'll go to keep each other alive and safe. The manga ends off with Midari grabbing Ayame's hand and saying "Lets enjoy ourselves to the fullest, together".
