Looking novels with 2 mc's something like Da tang shalong. Could be two male, male female, or two female.
Err, dunno (or maybe dun remember) about novel, but I do know some games, mangas and visual novels with multiple protagonists
Man, catching up to a protagonist story is already hard. And two? Meh.... Just like reading 2 novel in a same universe and time If its manga, i know arata kangatari
Try playing Odin Sphere, that's 5 protagonists. Oh right, does No Game No Life count? Seems Shiro's role is more of a heroine than another protagonist..... How about Durarara?
Shiro & sora count as one protagonist for me The protagonist in durarara are the group, not individual At least for me
Rakuin no Monshou And... What about a story with 108 main character? I just happen to know a classic with them. Man... It got so confusing each time we progress from a chapter to next one
