Summary of the Koko wa Ore ni Makasete Saki ni Ike to Itte kara 10 Nen ga Tattara Densetsu ni Natteita
You ever read that story? The one where the Hero’s crew basically gets totally wrecked by a massive wave of devils. Yeah, they're doomed from the start.
But then their top mage, Rakku, realizes how screwed they really are. And he pulls off this weird, almost crazy move. He tells everyone, "I'll hold 'em back for you. Go!" It's like... okay, I guess that makes sense if you think about his power.
His whole thing was using this super unique ability called 'Learning'. As his buddies bail on their adventure? Yeah, Rakku just stays put and starts channeling the devils' own magic against them. So fast he can learn new devil techniques, copy abilities, and basically weaponize their stuff almost instantly in battle.
Think about it: Drain Touch, then Hellfire Surge, maybe even pulling off nasty things like Abyssal Chains. He just keeps fighting, adapting non-stop, getting stronger as time goes on. Days blend into weeks, weeks stretch into years... it's relentless action for the main mage.
For ten full years straight? No exaggeration – Rakku basically clears out every single fiend that dares to show up near civilization. He becomes this legend himself through sheer power and survival, until eventually, he wins. All those devils are gone. The threat is neutralized entirely by his actions.
Then... you know the thing about when legends like him stick around? They get noticed in ways they didn't expect. His name starts popping up everywhere, people talk about it constantly. And then there's all this hype – giant statues of him being built over the city, glorifying a living legend?
Rakku knew he couldn't handle that kind of attention. He definitely *didn't* want to be treated like some mythical figure walking around in real life, admired and revered without context. So he makes another choice: go completely under the radar.
He keeps his identity secret tight. And here's the kicker – he registers as just an F-rank adventurer! Despite having skills that would make even S-rank mages green with envy. He basically walks around invisible for a decade, knowing everyone is talking about Rakku but calling himself 'just' an adventurer? That feels... weird.
