He given up on the sword because he was forced to fight too much in his past life (loads of his friends died while killing the demon lord in a modern ish past life it seems) so instead of working thru it and understanding sh*t just happens he decides to completely deny showing his sword skills in a medieval world where it would help him and his allies. The author is trying to walk a thin line to show he will hide his skills while being awesome I wish the best for this novel but I am done with reading it. These novels are too frustrating to wait for updates so I will come back at 300 to 400 chapters till then have fun reading if you try it.
MC – Hidden good guy personally while being somewhat of a typical arrogant OP bad*** MC. I like how the story has him act out the role of a noble demon king to hide the fact he has no communication skills. He is very powerful both physical and magical wise compare to the current enemies but that is just the huge gap in level so far. Also while leveling in the game before getting transported to this fantasy world he was never afraid of dying so he naturally is stronger then the people of this world with a fear of death whenever they go out to complete quests. They might introduce a rival that is at his same level which might pose a challenge but so far none has appear.
Heroines: typical Tsundere heroines that go dere fairly quick but still have somewhat typical female reactions to MC being somewhat of pervert. They are both somewhat annoying at the start. So far in the story there are two major ones.
1. Cat-girl, flat chest
2. Elf-girl, busty chest
3. Probably a dragon demonic beast girl Later.
He does not really power up through his own means at the moment all he has so far is two dragon sprits in him that lets him use scared flames from the light dragon, this burns his soul so he is killing himself, and he also befriended a King class spirit, top level for spirits under special class, while being the lowest spirit power which means he was not actually suppose to have such a powerful spirit. He is the lowest in existence before the MC takes over the body in this world and because he also comes from another world so it kinda hints the MC gonna be looked down upon for a while
