My New Life in Voltaire

Tachibana Hiro is a former hero in a world he wasnt born to. He was from Earth and died of old age, but due to leading a good life with influence and a caring heart, when he died he met a goddess that decided to reincarnate him in another world known as Voltaire. In Voltaire he was born as a hero and defeated the Demon King at a rather young age. All this was because he endured difficult training and he was now a master. Either way, he was now living leisurely and enjoying life with the occasional adventure.
