A brave knight named Oersted, a hero beloved by the people, defeats his best friend, the wizard Straybow, in the final round of a fighting tournament, winning the right to marry Princess Alicia of Lucretia. That night, she is kidnapped by the Demon King. The next day, Oersted and Straybow set out to rescue her. First, they find the heroes who defeated the Demon King thirty years prior, the knight Hash and the priest Uranus, and convince them to join. They fight and defeat the Demon King, but Hash dies due to the plague, Alicia is nowhere to be found, and Straybow is seemingly killed by falling rocks. Oersted and Uranus return to Lucretia in defeat. That night, Oersted is tricked into slaying the King of Lucretia by an apparition of the Demon King after seeing what looks like Straybow exit his room. He is accused of being the Demon King himself, and he is later imprisoned. Uranus, who is also a prisoner for being a "demon ally", uses the last of his strength to help him escape. Oersted returns to the mountain of the Demon King and finds Straybow alive, having faked his own death. Straybow reveals that, out of jealousy for Oersted, he sold his soul to become the next Demon King, and tricked Oersted into killing the King. Oersted is forced to kill him. He then rescues Alicia, but she confesses her love for Straybow and blames Oersted's heroism for Straybow's fall to evil, she then kills herself. Oersted, in his grief, searches through his memories and realizes that he no longer has anything to believe in, anyone to love, and that he has nowhere to go. Oersted snaps, sacrifices his soul to become the next Demon King, and names himself Odio, deciding to teach humans "the folly of their selfishness". He then takes revenge on all of Lucretia, killing everyone.
in this case the 22 demon lords introduced but less than 10 people ever talk up or doing something until c70
a battle maniac masochist elf who likes strong enemies, it's one trick pony character. Once the gap between normal taciturn into masochist is known, there's not much to explore in her character.
The male lead is a scum 90% of the series and the MC hates him, but by 10% of the story the author forced the guy to change into a good guy and then the girl magically just accept him.
The MC said to a reincarnator that she have been living in that world for years and it won't be like the game- that as long as people lives everything will change- she said that as if she have done anything significant in the whole story while actually she didn't. She's a doormat that's just being tossed around by her surrounding, and being lucky at the end for doing absolutely nothing. Her good ending is completely done via deus ex machina/plot armor.
Also if the moral is that the world is not a game, then why every single character is still acting like a very shallow and stupid game character? They didn't feel like a living characters at all. The characters are forced to be incredibly retarded so the MC can have her spotlight.
A man without a name who was doing slaughter in Japan, accidentally died without permission one day. But when he awoke he was a dragon in a different world. The man thinks.
That, you do not have to work on this?
Both the demon king and the brave became the strongest creatures at a toothless level, so it was a man who decided to live on leisurely as he liked.
Even the ending is noncommittal, that the author resuming it on a thousand years timeskip gaiden series with the same MC just to start another whole killing festival, with new characters to kill. Hillariously they releasing the seal for the supposed "hero" so they can be killed again, that world never learns.
