Union Student With Conviction [Male Reader X Multi-Crossover]

[This is another version of my other story, "The Convicting Mecha User"]

[][][][][]

Union Academy. A place where the next generation of heroes come together to fight off the threats that endangered the world. But about 75% of the population are those who have such abilities, while 25% are those who have nothing.

Yn Ln. A student of Union Academy. He was bullied by other students, for he is weak for having nothing. But others see him have great potential, due to his intelligent strategies and battle tactics.

Then one day, Yn voluntary expelled himself from the academy. So the headmasters agreed to his request. His friends felt sad for him leaving the academy. But his bullies were proud thinking that a weakling knows his place.

But what Union Academy doesn't know about Yn, is because he is a lot more than meets the eye.
