The continent of Aetherland is a world of magical beasts, swords, and magic.
Traveling the world on adventures and saving humanity from peril again and again: that's every boy's dream of becoming the hero of a comic.
Alan and Mayne, two orphans, finally get the chance to become swordsmen, and they take the potion without hesitation.
Alan feels the mana surging through him. He turns to share his joy with Mayne, only to discover that his head has already fallen to the ground...
"The path of the swordsman can only be trodden by those with steadfast minds and unwavering wills. If the reason you draw your sword is unclear, you may well lose control under the potion's influence and never recover."
[Western fantasy, conventional prose style. The advancement systems for swordsmanship and magic are the author's own. Ancient dragons, trolls, the catfolk, and other races will be introduced later. Conventional prose style, no absurd comedy and no System. The protagonist is a bit of a bleeding heart, but decisive enough when it comes to killing his enemies.]
I personally love these works: Lord of the Mysteries, Claymore, The Unbounded Mage, and Dark King.
