As a human being, you are running for the Demon King?
Tsunayoshi: Me! No! Think! Dry! Ah!
Tsuna, who accidentally traveled through the demon world, met a demon who called himself Mephistopheles. The demon knew his human identity and was willing to help him find a way home in exchange for Tsuna becoming a candidate for the demon king.
"Although there is no explicit rule, the candidate for the Demon King must at least be Black (5), so, young man, enter Babirus to advance!"
"Uh...?"
Isn't it weird that the devil still has to go to school?
Regardless, Tsunayoshi entered Babirus as a first-year freshman.
But the opening ceremony was far beyond imagination. The school song was a straightforward guide for human consumption, the chairman's speech was a passionate display of grandson posters, and the freshman representative's speech was a praising of the gloomy weather... Tsunayoshi's human common sense suffered a series of critical attacks.
Still, keep at it despite everything.
A journey to another world that is accompanied by joyful rants but with hidden secrets begins.
Purpose: World peace.
