The Other One is presented as a concept album based on a year-long hiatus that the members of Babymetal took from music, as well as the group's ten-year anniversary.

The magazine concluded that "it’s hard not to have fun when every track here feels suitably like its own adventure, and impressively still, Babymetal sound like they've been steering the ship through these parallel universes not for the first time, but for years.
