During Kiyotaka's and Kiyondo's early life, his grandfather, Toranosuke Ishimaru, was once Prime Minister of Japan; a title Kiyotaka believed he gained through his own natural genius rather than any hard work. After only a few months in office, the public opinion of Toranosuke changed from high praise to widespread criticism due to a disastrous scandal, and he was forced to step down. After that, his business collapsed and the Ishimaru Family was left mistrusted and in huge debts. As Kiyondo and Kiyotaka grew up, they both were doing a lot of effort in school to try to clean their family name and be respected. They were accepted in Hope Peak academy recently with Kiyotaka being the Ultimate Moral Compass and Kiyondo as the Ultimate Rule Reinforcer
