ooo this is a tough one. after thinking about it for a while, i'd say atsumu!! he's such a sunshine-coded asshole who lives his life like he's the main character [he's not but he should be], what's not to love?
as for an anime conclusion i'd change, hmm, i think i'd go with naruto shippuden. the ending felt really rushed with a huge pair-the-spares energy going on. while i appreciate not all the adults being married off in boruto, i do think only a small handful of the couples made romantic sense [shikaten, inosai] while others feel forced [naruhina, sasusaku]. also i had it pointed out to me some time ago how forced the kaguya plotline in the fourth war was and i have to say i agree. maybe hashirama could've tag-teamed madara with the other reanimated hokage, but the final victory needed to go to team seven. also the reincarnation stuff was soo. why did they do that T-T
