Reader's and Philia Bio

Instead of Naofumi Iwatani summoned as the Shield Hero, it was his little brother Y/N Iwatani who was summoned instead. Now Y/N must learn how to fight and survive, along with three other Heroes, in this new world to save it. But what if there was one more Hero that only a select few know of them. Will this Hero be Y/N Allie or will they looked down on them like the others.

Sorry if this description was bad. Lastly I don't own The Rising of the Shield Hero and Sword Art Online.
