Ahhh shipping. The blight of any fandom, but we all have our pairings that we like or have a soft spot for. So, here are my OTPs (One True Pairings) from Sentai.
First one, Gorou/Karen from JAKQ.
The first canon ship in Sentai. Yeah, I know Red/Pink tends to be a popular ship, but I have a reason to liking this pairing. It all started in the episode where Gorou got amnesia and, after it seems nothing was working, Karen decides to recreate the accident that cost her both her ARM and her FATHER to try and get his memory back. That's not just cool, that's what I call love. Plus, over the course of the series, I liked how we got they would switch around who would be the damsel in distress of that particular episode. Meaning there were moments where Karen was in trouble and Gorou would save her, but there were also moments where Gorou was in trouble and Karen would save him.
Second, Jou/Gou from Liveman
Seriously, these are just sooooo easy to slash. Plus, there the whole angst thing and how tragic it all is (Though they do get a happy ending... sorta). But what I really like about this ship is how their friendship isn't just something that mention once and never again (Like Yuusuke's crush on Rui) but is mention almost every time Gou comes back. Only downside to this pairing is that they scream classic Uke/Seme. Seriously, take a picture of the two together and add some blush on Gou's cheeks and you'll see.
Third, Takeru/Kotoha from Shinkenger
Now, I'm not a huge fan of Shinkenger, but I do feel this pairing is a little overlook by a lot of fans. It seems like there's some kind of unspoken rule that if you are in Shinkenger fandom, then you have to ship Takeru/Mako, Chiaki/Kotoha, and Genta/Karou. I know Takeru/Mako is unquestionably the most popular ship in Shinkenger and a lot of people actually thought the show was actually pointing towards it, but to me, if the show was setting up anybody with anybody, it's Takeru and Kotoha. Takeru has expressed personal concern for her and only her out of the vassal Rangers (Genta aside). They've shared an episode with pretty explicit romantic tension (Which annoys me how people try to write off that episode as just showing they are just Brother and Sister) and since then they've always gone out of their way to show Kotoha worried about Takeru's feelings in Takeru-centric episodes.
Both Takeru and Kotoha spent most of the series feeling like they were just nothing but a stand-in for the real deals and both feel more at home on the battle field than doing normal things, so I can see those two bonding over those things.
And that there's my ships.
