Because of this lead, Kotaro begins his investigation of where Gorgom possible store the tuna that they stole from various warehouses. While this is all happening, Katsumi, Kyoko and the sushi chef's son visited the sea, something that kid's father promised that they will do but they can't because of his injury. The reason behind it is simple; the kid wants to remember his dead mother. As for Katsumi and Kyoko, this scene showed us how much they miss Nobuhiko and their silent anger for Gorgom that the narrator revealed. What's interesting in this scene is that they sang their own version of "Long, Long Ago 20th Century", the ending theme of the series.
The final fight between BLACK and the Mammoth Mutant is once again, really fun to watch. For once, the Mammoth Mutant is able to pin Kamen Rider with his icicles. But nope, our hero has one trick left in his sleeve and quite literally, it is found in his sleeve in the form of his Power Stripes! Much to my surprise, the red and yellow stripes in his body can actually release energy that is strong enough to melt the ice! Now that the ice is thawed, BLACK performs the finishing moves, defeating the Mammoth Mutant.
