I would recommend: Fairy Tail (magic, strong friendship bond, good storylines, more than 200 episodes, ongoing) Akame ga kill (superpower, group action like seven deadly sins, some member of the group use sword as their weapon, super gore, tragic deaths) Highschool DxD (R18, group actions, use of magic, real good storyline, one of the character that belongs to the same household with the main character uses sword to fight) Sorry for the bad english, hope these animes suit you.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
