Mika makes a final attempt to convince Yui to join her, but Yui refuses, saying that she doesn't trust Chairwoman LeBlanc. Mika agrees to leave, saying she'll fight the She-hemoth on her own. Yui is surprised, saying that Mika has no chance of winning. But even if that might be true, Mika says she'll NEVER stop fighting... not when there are lives on the line. Yui looks conflicted, but doesn't follow Mika as she leaves.
Later that day, Hotaru the flame She-hemoth is on the move again, approaching the city. Mika pilots her F.U.T.A., the Sakura D, to try and stop Hotaru before it's too late. But the battle goes poorly, because Hotaru's flames are just too hot - the Sakura D's controls stop working due to the intense heat, and even Mika's communication with Chairwoman LeBlanc is cut off. Hotaru starts to give the Sakura D a handjob, which is bad news because if the Sakura D releases her serum too early, Mika won't be able to change Hotaru back to normal.
Just when it seems that all hope is lost, Yui arrives in her own F.U.T.A., the Bukka Mach K! Yui is able to get Hotaru off the Sakura D, and Mika is relieved to see the Sakura D's systems start functioning again. But Hotaru isn't defeated yet, so there's no time to celebrate. Yui demonstrates that the Bukka Mach K has a unique feature: several hoses that end in dick-shaped nozzles. Will these extra cocks be enough to douse Hotaru's flames, or are our heroes going to be toast?
