Mirai possesses a fierce loyalty and fearlessly puts herself in perilous situations to safeguard others. By skillfully defending Ryo, the school's popular heartthrob, from a vicious mob, she ascends to the prestige of class 1 from her previous placement in class 3. She subsequently confronts the overbearing members of class 1 to shield a girl from the lowest-ranked class, class 0. Following this, she voices her desire to abandon the hypocritical class 1. Sadly, her plea is disregarded, and she is punished by being removed from class 1 and relegated to class 0, accompanied by the girl she rescued and a mysterious boy she previously encountered.
Now the true test begins for Mirai!
