Black Lagoon

The Black Lagoon watch order runs 24 television episodes across two seasons plus a five-episode OVA, and this guide lays out the correct order to follow all of it. Begin with Episodes 1-12, the original run that introduces the Lagoon Company, then move straight into Episodes 13-24, the Second Barrage arc. Once both seasons are finished, close out with the OVA block covering Episodes 25-29, Roberta's Blood Trail, which is set after the TV series and works best as the finale rather than an interruption. There are no movies to slot in and nothing that needs to be watched out of sequence, so the chronological order and the release order line up cleanly here. Watch the two seasons back to back, save the OVA for last, and you will have seen every animated entry in the franchise without missing a beat.
