Koumoto Umi, a normal high school girl, falls in love with the pretty girl from the class next door, Segawa Shou. Even though she feels overwhelmed by her feelings, she can’t help but want to get closer to the mysterious Shou.

Our ages are different, our ways of life are different, everything is different. But...I just want to be with her.
Because I've never been in a miserable, tragic romance, I can say that unrequited love is fine.
I don't know why I fell in love with this person...it's a mystery.

They have different personalities, different ages, different ways of thinking, different looks, different everything.

This is the story of girls who clumsily make up for what's lacking in the other.

These are new side stories. Not a rewrite of the original serialized twitter comic.

Billionaire Tono Ryuichi, the President of Tono Foods Group, a giant food company, recently acquired two young female assassins from the Mexican cartel. Sui and Ai came from unimaginably poor childhoods and were given a choice between killing people or selling their body. They chose the former and went through an inconceivably extreme training and, at 17 years old, they have become one of the deadliest assassins in the world. They are absolutely obedient to their master and they are given the task of finding the killer that poisoned Ryuichi´s wife and child. They begin attending high school to blend into society and, at the same time, read and study which helps them become even more deadly on the field. Sui and Ai encounter Matoba Imari who is a high school assassin herself and may be more skilled than both of them. But unlike the two, Imari just wants to lead a normal life. Whatever Imari wishes for her life is not their problem, because the only things Sui and Ai feed on are bloodthirst and a challenge.

The mafia boss of the Iwashi family is a high school girl named Konomi Minoko. But don’t let her appearance fool you; she has done and seen things normal citizens can’t even imagine. Under her control are two assassins who have gained legendary status for their deadliness and ability to get any job done. Ishikawa Rushia, codenamed Baret, uses a modified handgun that uses a custom made hollow point bullet that explodes the target from the inside. Shirato Marin, codenamed Francesca, uses a original weapon that is a mix between a throwing axe and battle axe. Both of them are Minoko’s high school classmates and seem like normal teenagers but are two of the most feared killers in the mob world who handle missions often involving other assassins and underground groups.

Asumi-chan uses a lesbian brothel to try to find her childhood friend.

Now, as a second year in high school, she specializes in the masculine "leader" role—until one day, her partner suddenly leaves her. When Toribami Michiru, a short and pretty first year, shows up wanting to join the ballroom dance club, Kiki asks her to be her new partner, but Michiru reveals that she only plays the leader role—and she wants none other than Kiki as her partner.
