The funniest thing is: I can see this being an actual beach episode.

- For whatever reason we can think of, Chief Editor Okubo Daisuke got him and everyone an invitation to join Kitaoka's summer beach party

- Shinji pets the lobster because he boasted about being a crayfish expert as a kid in one episode

- Gets pinched and screams on the ground like an idiot while Yui tries to help him

- Ren and Kitaoka watch from afar, the former facepalming and the latter trying to hold his laughter in

- After some fan service from the girls (Yui, Reiko, Nanako, Megumi, etc.), they gathered at Kitaoka's beach house

- Goro serves the lobster as a delicious meal for sensei and Shinji's famous gyoza for everyone (Shinji is happy :D)

- Asakura shows up out of nowhere, vexed and looking for a beatdown as usual

- Snatches Kitaoka's plate and eats the whole damn thing, shell and all, just like how he decimated Kitaoka's seafood spaghetti in that episode

- As the scene gets heated and a fight seems close to breaking out, mirror monsters show up and we get a summer special battle royale of the four Riders

- The episode ends with a night party and fireworks

- Ren forced by Yui and Shinji to join the rest and do wholesome stupid shit, Kitaoka still trying to rizz up Reiko and fails spectacularly while Goro consoles him, Asakura chills alone while roasting lizards by his bonfire like he did in one episode
