This episode has two parts. The first part has burglars arriving at the Yorozuya with jetpacks and counts as a 30th anniversary Gundam special so there’s lots of Gundam references, and the second half has Gintoki, Kagura, and Shinpachi losing their hair.
Its due to situations like this that Katsura is probably my favourite character in Gintama.
They go in through the roof and then the ceiling. They have a lot of Newtype flashes, find Sacchan sleeping in the draw, and hide when Tama comes in searching for Gintoki.
They meet Sadaharu who when they offer him a treat he bites them. Hasegawa arrives sees that no one is there, eats the food in the refrigerator, takes a bath and wears Gintoki’s underwear.
Katsura arrives, they think that he’s figured out their identities however he is completely wrong. Gintoki shows up and things seem to be going well for them until Sacchan falls out of the cupboard, Gintoki beats the burglars up and throws them and Sacchan out.
Gintoki wakes up and smashes his alarm clock, there is hair on his pillow. After showering he finds lots of hair in his hands and in the drain, and that his hair has finned a lot. He meets Kagura who has also lost some hair after talking for a while tries to pull his shower cap off.
Shinpachi arrives and his hair is falling out as well, having lost most of the hair on the back of his head. After a quick meeting they try using hair growth solution(?) but nothing happens.
A segment of the opening is shown with them with their current hair, a section of the opening is also show with them wearing wigs, Kagura tries to shave them, resulting in them losing more hair.
It turns out it was a virus caused by Amanto, Catherine has hair growth solution that Sadaharu who has also lost hair eats. His hair grows back, and then more grows.
The Shinsengumi interrogate a suspect.
Something else as well…
