Black Lagoon Watch Order
3 entries · · community-maintained
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.

How this order works
AnimeChrono watch orders put every season, movie, OVA, ONA and special for a franchise in chronological story order, the order the events happen. When an OVA or movie takes place partway through a season, the episode range is split so it sits where it belongs. Entries you can skip are marked optional, and each order says where to start. Release order, sorted by air date, is a secondary view once every entry has a date. The orders began as a hand-curated set, and episode counts and air dates come from AniList. Fans maintain the orders from there. Any signed-in user can edit one. Edits from trusted contributors go live right away and the rest are reviewed first. Every change is versioned and can be reverted, and each order shows when it was last updated and last checked.
