The Bonds of the Four (四人の絆, Yonin no Kizuna) or Sailing 19 is the 19th episode of Mouretsu Pirates.


Part 1Edit

Gruier-Grunhilde ~ Lunch Meeting

Talking over lunch

During lunch at Hakuoh Academy, Gruier and Grunhilde talk to one another about being pirates. After Gruier mentions how she asked Marika to call them if another opportunity arose, Grunhilde notes how Gruier is such good friends with Marika but mentions that they shouldn't get too close, being a princess and a pirate. Gruier then says about how it probably wasn't a coincidence that Gonzaemon gave her the Bentenmaru's ID ring, claiming they were bonded by fate and destined to meet one another. Elsewhere, Marika is having a picnic with Mami but feels more like sleeping than eating. At the military hospital, the crew continue to relax as they wait to be released, noting how their captain should also being relaxing a little.

Following school, the yacht club gather in order to catch a shuttle to the relay station to carry out cleaning and maintenance work on the Odette II. During the bus ride to the airport, Gruier feeds a tired Marika sweets while Grunhilde looks on. Once at the relay station, the yacht club get to work on the Odette II. Marika, Lynn and Ai also come across some old dinghies, to Ai's delight.

After the yacht club finish work on the Odette II for the day, Marika takes a transport to the Bentenmaru to carry out some cleaning on the ship by herself. During the cleanup, she gathers a large amount of stuff which she isn't sure belongs to the crew or the yacht club and makes use of zero-gravity to assist with shifting it, with a slight mishap due to unseen mess. She barely makes it back to catch the last shuttle home, but forgets to lock the entrance though she sets the master lock on the system.

The next day, a sleepy Marika accompanies the yacht club to the relay station for the second day of cleaning. During cleaning, Marika helps Gruier with fixing a terminal but while doing so she trips over a toolbox and unknowingly loses her ID ring from her pockets, which floats out of the bridge and into someone else's hand.

Part 2Edit

During repairs, the yacht club find a problem with the engine room's safety relay and lack a spare, Lynn decides to try fixing it using stuff from the clubroom. Afterwards, Marika returns the Bentenmaru to continue cleaning and loads clutter into the shuttle to take back to the relay station for sorting. As she goes to catch the shuttle back to the Sea of the Morning Star, she receives a call from Misa who says that the crew are being discharged tomorrow and asking her to undo the master lock on the Bentenmaru after school. Back home, Marika has pot-au-feu with Ririka, who mentions that it might be time for Marika to start making it. When Marika asks if she'll teach her, Ririka replies that if she's the Bentenmaru's captain then she has access to the Kato family's secret, meaning she should already be able to make it.

Coorie - Eager to Return

Crew locked out

The next day, the yacht club are unable to fix the safety relay with the spare parts in the clubroom and Lynn decides to ask the fabrication club to make the parts though it will cost them a lot. Marika then receives a call from Misa who demands her at the Bentenmaru immediately. After rushing there, Marika meets with the crew who are locked out of the ship's systems. She then discovers that her ID ring is missing. The crew search the ship to retrace Marika's footsteps and find the ring but without success.

As Marika thinks back to when Gruier first gave her the ring, the yacht club arrive in the Silent Whisper and a transport ship, with Grunhilde having found the ring and had Lynn identify it. After unlocking the Bentenmaru's systems, Grunhilde returns the ring to Marika with Gruier reminding Marika of how it represents the bond between Marika, Gruier, Gonzaemon, as well as Grunhilde. Ai brings the Bentenmaru into the relay station's dock and the crew and yacht club sort through the clutter from the Bentenmaru cleanup. During the sort-out, several of the yacht club members ask Kane if he'd come back to the and San-Daime finds a fellow teddy bear collector in April, getting into trouble with Marika for not getting on with work.

While the yacht club head back to the Sea of the Morning Star, Marika slips backs to the Bentenmaru and while thinking by herself in the captain's room, stumbles across some hidden files with the ID ring, including the secret Kato family recipe for pot-au-feu. Later back home, Marika makes pot-au-feu for herself and Ririka.
