A young talented musician was performing on stage in the Christmas Talent Show host by the most prestigious school in Japan Ravenswood academy. However, Our Mc was unexpectedly summoned as one of the heroes that was selected by the Gods to fight for the humans in a war with the demons in a unknown fantasy RPG world.

The problem for our MC is that he is the youngest hero in history to be summoned to help the Humans in the War against the Demons. Will this factor affect his growth as a hero and his future war potential or hold him back from reaching his goals?

Will he survive together with his fellow hero companions from Earth and struggle together in the war for mankind's survival or will he choose the path of a lone wolf and survive in this dangerous fantasy world called Varindale.
