>>63228664Ragna is very 2000-2010ish anime protag: somewhat relatable loser, gets a harem of ladies from being nice-but-troubled, power is a result of tragic coincidence and being implanted with demonic influence, main motivation is revenge (actually wants to find out whereabouts of his little sister), goes through a ton of arguably ton of pointless suffering, outright trolling from big bads and ends up with huge act of self-sacrifice with 0 reward to himself
Sol is more of an 80-90s kind: confident, genius, natural womanizer but disinterested, powers are result of his own work and research, main motivation is revenge (full stop), story consists mainly of reverse trolling the big bads aside from the biggest bad because he's so fucking awesome, but there are chips in his armor and depth to the character that is unveiled the more you know about the story/setting, ending is getting his wife back and becoming a proper mentor/inspiration to new generation
