Siegbert dies in an unlucky accident and is reborn into another world, where his new family is warm and welcoming enough that his misfortune seems to be behind him. He expects to live a quiet, peaceful life, but that hope does not hold. In this world he turns out to have an absurdly high luck stat. Good fortune arrives as 'chances', and seizing them is said to make wishes come true. As he takes on each chance, the question becomes whether he can carry out the long-standing legacy his family has never managed to fulfill.
