Kill la kill harem x female blueberry reader

I don't like the fact there only male reader and no female reader, so I'm taking matter into my own hand and make undertale version of klk (kill la kill). Starting with underswap sand aka blueberry then work way up

(y/n) is one of the most sweet, innocent, and caring girl but she has a Secret she want to keep and don't want to remember. All while try make a new life for herself after well you have to find out when she go to Honnouji Academy, and get the attention of boys who would do anything to keep her that way with any mean necessary
