End-of-Year Big Cleanup (年末オソウジ Nenmatsu Osōji) is the forty-third episode of Engine Sentai Go-Onger.
At Hellgailles Palace, Kitaneidas and Kegalesia receive a surprise visit by one of the Gaiark's strongest ministers, Cleaning Minister Kireizky who had just finished cleaning the Braneworld of Prism World after the Sound and Magic Worlds before coming to the Human World to aid the Ministers in cleaning it of the Go-ongers. After getting the Ginjiro-go ready for Christmas, the Go-ongers respond to the Gaiark sighting and are ambushed by Kireizky's sniping, revealing himself to be the one who sniped them during Engine-Oh G9's fight against Bin Banki before sending Go-on Red flying after the Go-onger rushes at him. As the Go-on Wings' cover the others' escape and are knocked off themselves, Sōsuke encounters a wounded man in a Santa Claus outfit. After the man proves himself to be the real Santa Claus by showing Sōsuke the Christmas present from his childhood that inspired him to follow his dream to be a racer, Speedor reveals Santa to be from another Braneworld, Christmas World. After being contacted by Bomper while offering to help Santa, Sōsuke takes him to the Ginjiro-go after Kireizky had wrecked all the Christmas work there while defeating the remaining Go-ongers who despair over Kireziky's combo attacks. To fix things, Santa gives the others the inspiring presents from their childhood as Sōsuke sets the tree back up and encourages the others not to give up for the sake of the children with Renn showing interest in Santa's bag. The next day, Kireizky is about to sweep the city of Christmas and its population just as Go-on Red arrives in a Santa Claus outfit to fight him with others popping of the bag to get the Rag Grenade off him as the Speedor-powered Go-Roader makes a hit on the Minister. After defeating him with everything in their arsenal to take out his, the Go-ongers return the bag to Santa. However, Kireizky survived the attack through his Bottomless Wastebin as the Go-ongers stand him down.
