Inomaru

Inomaru is the femslash ship between Maria Inomata and Ushimaru Yuki from the School Babysitters fandom.

Canon
They met when Kashima rejected a girl while the girls were secretly hiding and listening. Ushimaru tells Inomata that that meant Kashima rejected both of them too, which Inomata says that it wasn't like that, that she wasn't there to spy him or something like that. When she said that, Yuki smiled and asked Inomata if she could call her by her first name (Maria), which Inomata blushes and says that she can't, since her name didn't match with her but Ushimaru calls her like that anyway. Next day, Inomata went to Yuki's classroom and Kashima thought that Inomata made quite a friend.

When Ushimaru was 'spying' the kids and Kashima, Inomata appears and asks Ushimaru what was doing there. Yuki said as an excuse that she was picking a ball that fell down, but Inomata notices the 'lie' and she said that she knew how Yuki felt, and while blushing, Inomata said that the kids were cute to her too, and asked that she can make company to Yuki for 'spying' the kids, which girl was shocked and Inomata said that it was fine not going with her, but Yuki ran to Inomata grabbing her arm saying that it was better watching the kids in a certain distance. When Kashima heard Yuki's words later, Inomata said that if he heard, that would speed the things a little and told him that she and Yuki were going to get in with the kids. Yuki got surprised at that answer and Inomata grabs Yuki's arm while saying to Kashima that he needed to help Yuki to get used to the kids. After that, Inomata dragged Yuki a little far away so Kashima wouldn't listen what Inomata was going to say. Inomata asked Yuki if by meaning that if she was not good with the children, it would mean that she would hate them, which Yuki declines and Inomata said that it was fine, now it was her turn for getting used to the kids while Ushimaru blushed and complained a little.

After Ushimaru wakes up in the Infirmary because she passed out, Kashima was with her, which Ushimaru apologized to Kashima by making troubles and by that, Inomata might be disappointed too. Kashima said that it was fine, that he just got used to the kids, and after he said that, the kids came to the Infirmary and apologized to her for the problems they made, while they were holding mini-flowers with them. Yuki accepts the apologize by picking the flowers and then Ushimaru asks Kashima where Maria was, he said that she left the place first and Inomata told him if he could apologize to Ushimaru by forcing her taking care of the kids for her. Ushimaru thanked Usai and Kashima for taking care of her, but she had to reach Inomata, and then left the place. Kashima made a smirk at that answer. When Yuki reached Inomata, she hugged her while apologizing and thanking her saying I love you to her, while Inomata blushed at that answer and Yuki said in her mind: The one who gave me the opportunity to change, it was the friend who I love, referring to Inomata as the friend she loved so much.

Fanon
This ship sailed as result of their 'rivalry' to see who gets Kashima's love first, but it also sailed due to their ever-increasing sisterly bonds.. They also can be considered as the common ship made up of a tsundere person and the typical loving person. (Inomata as the tsundere one, and Yuki as the loving one). This ship can be shipped along with Hayaryuu too and Inomaru supports that ship too, because these ships overlap and can be a prime example of ship mates.

This ship only haves 20 works in AO3, but it's the most written ship for both characters and it's the second most written ship in the School Babysitters fandom.
