Arifureta: From Commonplace to World's Strongest (Seasons 1–3)

Arifureta: From Commonplace to World's Strongest (2019) is a dark fantasy anime you can watch online on iFILM. Based on Ryo Shirakome's light novels, it follows an ordinary teen who gets summoned into a brutal isekai world and left to rot.

Hajime Nagumo's whole class is pulled into another realm to fight as heroes. Everyone else lands a flashy combat class. Hajime gets Synergist, which basically makes him a blacksmith with no armor, and his classmates never let him forget it. Then a dungeon raid goes wrong, betrayal drops him into the deepest pit imaginable, and the only way to survive among monsters is to eat them and stop hesitating. The boy who claws his way back up is not the same one who fell.

The show opens soft and then turns genuinely grim, swapping the bullied underdog for a cold, ruthless killer who collects power and companions alike. Expect harem beats and big fights, but with a harder edge than the usual portal fantasy. Good for fans of revenge arcs and slow, savage power climbs. Stream every episode of Arifureta online on iFILM.
