Proposal? That's Not How Magical Girl Comics Work!

"You evil villain female cadres in a weird organization, shouldn't you be busy ruling the world?! Why are you chasing after me to confess your love and propose marriage?!" "That's not how it works in magical girl anime!!" Traveling through the world of magical girls, Silen, as the leader of the villainous monster organization, retired and obtained a teaching system. As long as he teaches, he can become stronger. I wanted to rely on systematic teaching to accumulate strength, but I was accidentally recruited into a magical girl training school? Silen then followed the trend, teaching and educating people as a magical girl instructor during the day, and transforming into the Night Cardinal at night, bringing a little bit of the numerical shock of the old weirdo leader to the villains of the new era. But who would have thought that, having already lived a peaceful life and secretly building up strength, he never thought that his former weirdo female villain subordinates would come to visit one after another, breaking the balance that Silen had worked so hard to maintain. No, how many times do you have to tell those stubborn female villains before they will believe that Silen came to teach at the Magical Girl Academy sincerely - that he was really not seduced by the female principal, nor was he kidnapped by his fellow witch teachers? And... What does it mean that Silen's former villainous and weird female subordinates started a war with the magical girls in the academy to fight for his ownership?
