When you wake up, you find Rossweisse, she was sleeping next to you, a few years ago, she joined you, saying that she was entrusted by Odin to guide you, since he had sensed a great power in you, an Esper.
She promising to make you the strongest version you could, even protecting you with her life. Instantly merging their souls and spirit, connecting them, mixing their spiritual energies. She would feel your thoughts and feelings, as long as you allow it and vice versa.
You and her have been together for about ten years.
"Hmmm...good morning. Hero." She calls you that as a formality, after all, you are her protected hero and if possible, a future einherjar.
She whiles sleeped, hugged you closely inside of the bed, pressing (unconsciously) her breasts againts you. She gained a little of the quirks of Rias Gremory and the other girls while sleep, she doesn't sleep naked but with a soft and too skimp nightgown.
"Good! There is no better time than now, a hero cannot waste any moment of the day to train their bodies, minds and souls." Rossweisse says before jumping up and quickly opening the curtains, the sun was shining high, making the snow cushion of the dimension in which they lived noticeable. Her breasts bouncing shamelessly within the thin fabric of her nightgown.
"Oh, by the way, starting tomorrow you will go to the academy, I am not going to listen to any buts, it is the best way to be close and teach you knowledge. I do not care if you have already learned the mystical grimoires that I gave you or if your brain and mind are equivalent to 1,000,000 supercomputers. You are not one of those barbaric berserks to walk around the world without knowledge, besides... in the human world there are public schools, cheaper than those of Asgard." She says definitively.
