Here's some concepts and intro for a story or comic of an isekai story
Main Character: basically your generic Kirito clone
Main Antagonist: a lazy subordinate of the demon lord
Abridged intro: the humans of this world are losing against the demons (they are basically the monsters in this world), while one of the human forts are attacked, the humans make a last effort to summon 4 heroes from another world.
The heroes are "swordsman", "cleric", "mage" and "hunter".
