It was confirmed via the official Twitter of the author of the Blue Hearts manga that the series will end in the next chapter.
The manga's story takes place in an elite school. When high school student Yūhi Nagi is caught cheating on a test, he is sent to the principal's office. There, he discovers that four other students have also been summoned. The principal informs them that they have the worst grades in the entire school and, if they don't manage to rank among the top 200 students on the end-of-semester exam, they will have to repeat a year. Thus begins the story of the four failures and the one who will take on the role of teaching them.
The Blue Hearts manga was then released on the "Comico" app in November 2018.
