Education is the most powerful weapon which you can use to change the world., Nelson Mandela
Ambrose Salavia is a genius mage who works in the magical beast research department of the Second Academy of Magic. He is the only immortal mage at the institution who hasn't quit, and a rising star in education.
He currently has two major problems: he's broke, so he tutors after work and works as a hunter on weekends; and the childhood sweetheart he has a crush on lives in another city.
The Second Academy of Magic welcomes a new faculty member: a young lady from a noble family, and an accomplished immortal mage. When Teacher Salavia arrives at the welcome reception, he suddenly realizes: Isn't that my childhood sweetheart?
Vita Cletus is a genius mage who works for the Maple Courtyard, the agency that oversees magic. His code name is Peregrine Falcon. He is the youngest leader of an operations team in the agency, and the headmistress's most favored student.
He currently has two major problems: the childhood sweetheart he has a crush on lives in another city, and he doesn't know their sexual orientation.
Recently, Agent Cletus happened to accept a mission involving the Second Academy of Magic and applied to the headmistress for permission to take on a female identity. While carrying out the mission, he plans to secretly check up on how his childhood sweetheart is doing.
His question: We don't even know each other, so why does he keep watching me instead?
A slightly less ridiculous blurb ↓
Genre/plot: Magical academy and episodic mystery-solving.
Characters: Dedicated university professor x cross-dressing mage agent (probably).
Romance: They switch roles; childhood sweethearts and mutual pining.
P.S. Before his identity is revealed, there are no scenes of Vita approaching anyone while dressed as a woman. He doesn't usually disguise himself as a girl. He's just an adorable boy who likes shorts and skirts (?).
Theme: Study hard.
