Be careful what you wish for. You could get some more Deka jumping out of a flying train yelling "Ore sanjou!" and striking a weird pose.
I'm not going to say that it's not going to happen, but judging from Umika's flashback I kind of doubt it. Umika has a school uniform with two stars (second year) on the lapel, which leads me to suspect that the girl who got "iced" was Umika's "beloved senpai".
I like the episode, it made me laugh. I am getting a lot of Gokaiger vibes from the Lupins so far.
