Copy and paste? The plot is common, the characters is like the one you often see and what a coincidence the characters are the type I don't really like and the drama, NAH it's literally copy and paste from the other anime, and the words and sentence is common, It sounds like this is the author's first work. It doesn't hype me or intrigued to read, and the info about mana, sword can be seen is sword comics too, no new info?
Well, the author might improve...
