Reformation in Another World: Starting off a Public Work with Earth Magic

Michio Tsuchida (aged 35), who lost his life after saving a little girl from a random attacker, woke up to find he reincarnated in an unknown world to him. One day, Michio, who now has to live his new life as San José who's the son of a noble family, gets baptized in order to receive a skill. He received several magics and unlimited mana, starting off with "Earth magic" in said baptism.
