Gintama Chapter 601 has a brief Shingeki no Kyojin reference!

A LOT of context is needed if you don’t follow the best series ever Gintama, but generally speaking what you need to know is that 1) Aliens/Amanto are targeting earth in the current story arc and 2) Gintama is getting a live-action film adaptation in 2017 starring some well-known Japanese actors, including Oguri Shun (Playing Gintoki) and Suda Masaki (Playing Shinpachi). Of course, with Gintama being Gintama: they have to break the 4th wall and make fun of all this.

My translation of this page:

Gintoki: (Weekly Shonen) JUMP is in more danger than the earth right now. While I wasn’t paying attention Bleach and Nisekoi both ended and I turned into Oguri Shun. Is JUMP doing okay…?

Shinpachi: You know you’re still part of JUMP, right?? Your days are numbered!

[T/N: Gintama is serialized in Weekly Shonen Jump, and it’s also in its final arc right now :(((]

Gintoki: Shut up already. Aren’t you here, too? Last week you even abandoned protecting earth and only played Granblue Fantasy on top of a building the whole time.

Shinpachi: I WAS NOT PLAYING THAT!

[T/N: Suda Masaki, Shinpachi’s live-action actor, often stars in the commercials for the mobile game Granblue Fantasy]

Gintoki: I don’t understand it. Why do you get to be Granblue Suda? Other than two straight legs that you use for walking, you don’t resemble each other at all.

Shinpachi: NO PERSON CAN PLAY THAT KIND OF CREATURE!

[T/N: If you are not familiar with Gintama, a running gag is that the name “Shinpachi” actually only refers to Shinpachi’s glasses. It’s a long story…don’t ask]

Gintoki: Not to mention Oguri and Suda are 184cm and 176cm tall. The appeal of our live-action versions seems too strong - how many cigarette boxes are they trying to sell?? What kind of movie even is this?

[T/N: The SnK-like Titans are there to showcase the immense height of the actors]

Shinpachi: It’s you who is overstating things! Kagura has now been reduced to a single cigarette’s height!

[T/N: Kagura is the third member of the Yorozuya trio with Gintoki and Shinpachi, she will be played by Hashimoto Kanna, who is only 152cm]

(Not going to translate the last panel since it’s not too relevant)
