Battle junkie MCs with will bordering madness Some references to give you an idea: Eren Yeager (pre timeskip) Kenpachi Cid Doomguy Goblin Slayer Asta(not so much a battle junkie but kinda fits) I can't think of anymore vanilla examples Quick disclaimer the above stated examples are just to you give an idea of what I am looking for, it doesn't mean I am looking for anime or manga I would appreciate it if you kept you're recommendations to strictly LN, WN and novels I am not really looking for long form media as I as of right now ~Thanks in advance~
Try watching Drifters and Kengan Ashura. There is also this manga titled Teppuu tho it has fmc. Still, I highly recommend it!
