A robot boy drifts alone through the cosmic void after sacrificing everything to save Earth. When the musical group ravex discovers him among the stars, they accomplish the impossible: resurrection through an otherworldly version of Black Jack's healing arts. Reborn as Ratom, this evolved android awakens to find himself part of something larger than his original purpose. Legendary Tezuka characters materialize throughout this strange new reality, guiding the boy through encounters that blur the line between past and future. This OVA exists as a love letter to Osamu Tezuka's legacy, fusing his iconic characters with contemporary music culture. Rather than tell a traditional narrative, it weaves together visual storytelling and performances by international artists to create something that feels more like an elaborate music video than conventional anime. The atmosphere is surreal and celebratory, honoring both Tezuka's 80th birthday and Avex's two decades in the industry. Viewers drawn to experimental anime, music-driven storytelling, or the deeper cuts of Tezuka's universe will find something genuinely unique here: a collaboration that treats animation not as a medium separate from music, but as its perfect partner.
