I love the concept of a tokusatsu hero and villain falling for each other, it just sucks that so many of the manga based on it either all end early or get axed.
Knowing Hiro Mashima, he'll probably try to give some kind of backstory to make Kurenai sympathetic or attempt to give her some kind of redemption before concluding the arc. At worst, she'll probably be killed off by a different villain, though not before trying to protect Homura or something...
It took me hours to beat this boss and they killed it like it's small fry!? I know that it's an early game boss, but that just rubbed some salt on my wound.
