The Dolphin Orphenoch arc. Just the reveal of the Love Dodecahedron, which can be summed up as Mari looking really awkward, Naoya staring at her like a lovelorn puppy, Yuka staring at her with a Death Glare that makes her look like Sadako, and Keitaro looking at Yuka like a slightly more lovelorn puppy. No, really.
And after that too. There's something about seeing half the cast sick as dogs for no reason at all.
The episodes where Keitaro and Kaido inexplicably become bros and decide to go punk, complete with the dyed blonde hair. In 33, Kaido demonstrates this by dancing to loud punk music and Yuka is totally into it!
Takumi is not much of a technical fighter and his transformed battles are pretty much brawling. He acts so bruttish, like a bar brawler or some guy fighting in a stadium or even a concert that it becomes freaking hilarious.
So, there's this new Orphenoch/Rider in Paradise Lost. OK, then - WAIT, IS HE SPEAKING PERFECT ENGLISH?
Better yet. He's played by a Chinese actor (making him the first non-Japanese Kamen Rider).
