Nira opens her eyes, revealing that she was floating in some sort of void dimension. She sat down as she continued to float. This dimension looked like the one described in the book as memories of that book flooded in.
"The Reincarnation Dimension." She muttered under her breath. This wasn't heaven or hell; it was the reincarnation room.
She floated into many worlds. She saw herself in those different worlds; she had other multiverses of herself.
"Well, that's interesting, well..." Nira made a struggling sound as she stood up. "I hope I'm the original." The void dimension finally ended as she saw a distant light just straight ahead of her.
"This is it." She muttered. "This is the time I get reborn." Nira walked closer to the light as she touched it with one of her fingers, and it seemed peaceful on the other side. She still needed to process everything, but she was just too excited.
"No... no need..." She thought with a hiss as she went through the light. She could hear and feel herself disappearing and reappearing in some sort of grassy landscape. She could hear birds chirping as she finally opened her eyes to reveal that she was in a meadow.
"This looks cool!" She muttered as she processed her surroundings: colorful trees, grassy grass, and a cooling sunrise.
She then looked below her and saw her gun.
"Yes! Now I have a higher probability of surviving in here." She said. "Now I don't know if this is a forest or a forest from another world, but I feel like myself and that nothing changed."
She took her first step into this world as she decided to explore. "Exploration is needed." Exploring the maze of the forest, she saw many interesting creatures that revealed she was in another world.
Bunnies with a forehead horn, floating wolves, and more things she saw, like a turtle crab-like thing. While exploring, however, she saw a small hut. It looked like a witch's, and she decided to explore it.
Stepping foot in as she creaked down, she saw many potions and possible grimoires. She grabbed one as she sat down at what seemed to be a desk.
She opened the first page of the book, and it was all about mana. It read:
"Mana is an important thing when producing magic. You can't have magic if you don't have mana. In this world, mana is almost everything. Spells, techniques, and even training itself require mana. But one question is how to evolve it..." She opened the second page, intrigued by all this magic and mana stuff.
"In order to make the maxes the minimum, you need to train. Yes, you are required to have mana when training, but you can also use stamina. Just dash and sweat yourself, and your mana will be all right!" She then closed the book. She knew the fundamental stuff of mana. Now what she needed to learn was how to actually cast magic spells.
