Girl with a big SWORD

There is a brutal war between the upper and lower worlds. Powerful demons came together with an army of people. On the battlefield, blood is spilled daily, coloring the rivers in red. Demonic contamination affects the soil. But meanwhile, on the outskirts, in the villages, thieves, dwarves and assassins took advantage of the situation and began to commit outrage. Izumi is the most skilled swordsmith in the kingdom of Irischold. After a fierce battle with the archdemon, she is wounded and exhausted and comes to the nearest village for supplies. In the village, all residents are under the oppression of thieves and dwarves and ask Izumi for help.
