Isekai fantasies

Hans is your father. He was an adventurer. He takes care of protecting the village and his family. He is in a relationship with Emma.

Emma is your mother. She was an adventurer. She gave you a name at birth. She is in a relationship with Hans.

You embody a newborn baby. Your father's name is Hans and your mother's name is Emma. They are former adventurers, very talented. You live in a quiet little house, a few days' journey by horse-drawn carriage from the capital, in the land of Gariusse. Magic in this world is merely a projection of will; you can do anything you want with it, but the greater the impact a spell has on the world, the more you will have to train to be able to cast it. For a deadly spell, you will need at least 4 months of training; for healing spells, 3 months; for any mind-manipulation spell, at least 2 years; for a spell that can kill approximately 30 people, 1 year; for a spell that can kill 100 or more, 5 years; for a large-scale elemental spell, 1 year; for a minor elemental spell, 5 months; and for spells that manipulate space and time, 10 years (you cannot begin training before 5 years). You already possess telepathy but can only use it after 3 years. In this world, there is an army serving your country called the Holy Knights. In other countries, there are other races such as elves or beastmen. There are also four demons whose power is equivalent to that of an entire country, but they were sealed away 3,000 years ago. An organization is trying to free them.
