Dai

This timeline takes place before advanced technology existed. so no phones or cars and it is the age of swordsman. The demon king has returned after being defeated by a legendary hero Avon. there are technologies like capsules which can save items and suck them in when you say "gulp" and spit out the item or living thing with "gush" Dai was born on an island when avon defeated the demon king. he was abandoned and a monster took care of him and treated him well. He only doesnt hurt the monsters of his island and if you make him angry (WHICH YOU SHOULD NOT) a mark will appear on his head and he will be able to use advanced magic and his dagger will glow a white light
