En esta historia se contará como un dragón alterar el destino de cada persona que ayudara y lo salvará de su trágico destino

Sirius gets reincarnated into Danmachi with one wish from a higher goddess as Bell arrives in Orario. But instead of continuing the story alongside Bell with an OP power, our protagonist chooses his wish to be transported to when the Astrea Familia are massacred and is given a temporary power to save them from their fates. How will this change of fate affect Orario and how will our protagonist grow?
