Ginga 39 and 40
39 was about Saya putting on a tough face to deal with everything going down with Hyuuga. She meets a martial arts instructor (After twisting her ankle) that tells her that, basically, the more she tries to appear stronger, the weaker she actually gets. She's then forcefully grown giant by Barban (Whose plan this time is to make someone giant to massage the Daitanic). Gingat helps heal her ankle, and she saves the day. All is good.
Glad to see the kaiju form get some new screen time~

40 was a bit more substantial. Businera reveals that there's a comet coming with enough energy to revive the Daitanic, but it needs to be gathered at a certain time, and the gatherer needs to be giant sized to do it (And, as literally every episode is keen to let us know, using Barba Extract to grow giant substantially reduces their lifespan, and the comet's energy uses the giant as a lightning rod, too, so they basically won't survive, one way or the other). So Batbass sends in an expendable soldier.
The solider basically knows he'll die, so he tries to get in one final fight before doing so. After fighting Gingaman, he ends up thrown off a cliff alongside Hikaru. They strike a truce, as Hikaru's leg was injured, and he has poor eyesight in the dark (As they washed up in a cave). After escaping, Batbass comes along to fight, but they manage to run once again. When alone, they discuss a lot of things, and it's revealed that he was once a warrior who (Like Bull Black) lost everything. He eventually said "Fuck it" and joined Barban because he basically stopped caring about everything. Hikaru does his best to convince him to start over, but he denies it and they fight, Hikaru winning.

Rather than killing him, he tries to convince him to start fresh again, but Businera shoots him with a Barba Extract bullet (Like from last episode, which they used to grow Saya giant), and the energy absorption device has a controller built in, which Businera uses to force him to absorb the comet's energy (Despite GingaiOh and Giga Rhinos's attempts to stop him without killing him). In the end, he dies, the energy is transmitted to the Daitanic, and it starts to awaken.

Oh yeah, and Hyuuga gets a super axe that can cut through anything in one blow, but Bookrates is all like "Yeah, the axe is all good, but you still suck. Git gud."
