Metaphor: ReFantazio‘s “Battle Theme” erupts with thunderous brass and pounding drums, turning routine turn-based scraps into pulse-racing spectacles that pull you right into the fray. Shoji Meguro amps the drama by weaving in rhythmic chanting from Myōhō–ji temple’s chief priest, Keisuke Honryo, sung in the international language of Esperanto for that timeless, cross-cultural resonance which makes every Archetype clash feel profoundly ritualistic.​

The rhythmic Esperanto vocals loop hypnotically over surging strings and synth pulses, cresting with victorious horns that time perfectly to weakness chains and squad synthesis attacks, mirroring the combat’s strategic highs. This primal chant roots the fantasy battles in spiritual depth, evolving Atlus’s sound beyond synth-pop into something hauntingly primal that lingers post-fight.​

It anchors the award-lauded OST’s standout moments, those monk-delivered Esperanto lines lending legendary weight to even basic encounters—though their fervor can overshadow subtler scenes.
