Gai Pants, a podcast to talk about which GaoGaiGar characters fuck

...see this one doesnt work because the series is already too busy giving us canon answers for everyome

Does Gai know what sex is? Yes, its a plot point that his and Mikoto's relationship is strained when he's a cyborg in part because they can't fuck.

Does Gai fuck? After the original series yes, and a lot. But the Bettermen want to stop him because his genes are too strong and would destroy biodiversity down the line.

Does Mikoto fuck? Yes and she's also a strong proponent for birth control and wants to adopt kids instead of getting preggers herself. Also, she's superhuman so she and Gai probably have a blast shielded room to fuck in for everyone else's safety.
