Emotional thrill-ride is perfect 2 words for this manga. Also art is SoO good
tiny SPOILER*** no major stuff like plot or arc
From the very first chapter you will see dark, violent, cold, slowly dying world w/ eternal despair of Agni.
My personal favorite arc was 10 years of peaceful life after all pain mc went through, it showed a glimpse of what could've been if Luna never died.
Many people weren't ready for the idea of being selfish(letting world blow out)
*Tatsuki Fujimoto’s crisp yet frenzied artwork, his refusal to pull a single punch, and his raw approach to both writing and drawing make Fire Punch a post-apocalyptic journey worth taking.*
Of course it's not typical vanilla manga but extraordinary unique manga.
