The Many-Faced Wanderer of Runeterra

Ron transmigrates into Runeterra from the game League of Legends and obtains a System that allows him to disguise himself as anyone he has come into contact with, while gradually unlocking various unique abilities.

Because of this, beginning in the year 985 of Noxus, he can repeatedly change the destined outcomes of numerous events, ultimately becoming the terrifying figure known as the "Many-Faced Walker"!

However, when Ron first arrived in Runeterra, his situation was far from ideal:

"LeBlanc, how dare you use me as an experimental subject? Just you wait!"

Wearing LeBlanc's dignified and noble face, Ron fled for his life while swearing viciously: "Just wait until I shake hands with the Celestials and trade fists with the Ascended. You are definitely going to pay for this!"
