So the MC was enrolled in an academy of some kind; with noble or rich influental people. This academy had factions that was competing with each other. Mc is very good/strong/straight up OP with whatever the academy was teaching (magic, mecha, alchemy, martial art, etc..), therefore those factions were trying to invite MC to join them. Any recommendation? Jp, Kr, Cn, Original are fine.
do you want MC to be from lower class or is it ok if MC is also noble/influental? what if MC want to create a new faction?
Crossing to the Future, it’s Not Easy to Be a Man Spoiler MC from influental family but is secret. Mecha, OP. Create new faction, fight with the other factions
