The setting is the Royal Manalicia Academy.

Rankings exist from X, S down to F. It is an academy permeated by an absolute social hierarchy based on mana and class.

It is physically, magically, and mentally impossible for those of lower ranks to defy those of higher ranks. When an S-rank or higher student passes through the hallway, it is a punishable offense of 'Lese-majesty' for a D-rank or lower student to make eye contact. S-rank and X-rank students possess the 'Absolute Requisition Right,' allowing them to legally seize the property, dignity, and physical freedom of lower-ranked students at any time. One can refuse, but must win a duel to earn the right to say no. Even the faculty cannot defy high-ranking students of S-rank or above.

But who cares about that?

You just want to hit the honeymoon goal at the rendezvous point with an arrogant, shark-toothed, blindfolded devil contractor who uses magic bullets and evil eyes, calls herself 'Washi,' and is a total klutz, right?

These lyrics are so me...
