Baby 5 and adon Sais marriage.
Another wedding, luffy has to be there to see his friend getting married especially after he and 5600 others attending are his sworn subordinates. Its also Jenbes firzr movie apperance as a strawhat. Theres a beautiful wedding, Sanji is flirting with all the brides maids, everybody is in tuxs and nami and Robin are brides maids.
Sai says his I do's but the fun is interrupted when during the banquet when the wedding is attacked. Marine Vice admiral Green Bull is there with a fleet of his own along with the Cano countries army and Smoothie leading a ship of BM pirates.
Three large woman appear before before Sai and Luffy(aho are in tux btw). The three take turns explaining to the Duo why the marriage cant go down. In generic bad guy fashion Admiral green bull explains that Luffy has been gaining to many royal backers. His knowing so many kings and princesses is a direct threat to the WG. She also list off Boa,vivi, shirahoshi and Rebecca. Who may or may not be there
Smoothie says this is payback for crashing big moms wedding.
The third woman is an oversized human from the Cano country who is the princess warrior of her country. She takes Baby fives and dips.
Baby five was actually the princess of her village
