2. DanMachi (God's Blessing on This Wonder)

The foundation of modern isekai: Often credited as the push that revived the isekai genre in the 2010s, DanMachi set the standard for protagonist’s growth, world-building, and complex character arcs. Its unique take on “outsiders rising” through determination—and steeped in mature themes—bridged fantasy with relatable human experiences.

The emotional core: Though more somber than flashy, Re:Zero revolutionized isekai with its heavy focus on trauma, mental resilience, and moral ambiguity.
