GP 20: Siblings Battle!?

Siblings Battle!? is the twentieth episode of Engine Sentai Go-Onger.

Plot
While Miu is out shopping, Hiroto is at a café with a blonde woman when he is contacted by his mentor. Saki sees Hiroto trying to rebuff the woman and mistakenly assumes that they are in an embrace. Suddenly, Nokogiri Banki, now rebuilt as Chainsaw Banki, arrives to destroy the city. The dust cloud created by Chainsaw Banki's destruction renders the Go-ongers unable to locate him. The Go-on Wings arrive as the dust settles, and each of the Go-ongers reveal that they have seen Hiroto out with one of at least five different women. Miu is upset by the news as Chainsaw Banki escapes after gathering some information Hiramechimedes needs. Miu later discovers that each woman had been exhorting Hiroto to pursue various alternative careers, and Hiroto had rejected all their offers in order to be a hero. Feeling that she has ruined her brother's life and derailed his future, Miu rushes off to battle the Gaiark on her own. The next day, the Go-ongers find Chainsaw Banki making sawdust as part of Hiramechimedes' plan. An agitated Go-on Silver joins the Go-ongers as Chainsaw Banki cloaks himself in a cloud of sawdust. Go-on Silver is goaded by Chainsaw Banki into firing at him, which she does, igniting the sawdust just as Hiroto arrives. He reassures Miu that he fights as Go-on Gold not out of obligation to her, but because he truly wants to. The Sutō siblings reconcile as their instructor, the giant Engine Jum-bowhale, arrives. After putting out the flames, Jum-bowhale deals with Hiramechimedes and the Barbaric Dohma SP swarm. The Go-on Wings battle Chainsaw Banki together and defeat him. Chainsaw Banki is Industrial Revolutionized as Hiramechimedes escapes. Jum-bowhale calls Hiroto and Miu to join him, and the siblings bring Toripter and Jetras to the battlefield to form Seiku-Oh with their instructor. Chainsaw Banki is outmatched by Seiku-Oh and is scrapped. Afterwards, Miu exuberantly promises to support Hiroto more, which unnerves him somewhat.
