Chivalrous rivalry that Sela is annoyed with because she see's Leo's reluctance to fight at full strength as "You holding back your punches and that makes me feel like you think women are weak fragile flowers and can't take a hit. And I can take a hit. So punch me. Do it. Treat me as a worthy opponent and kick my ass." Which, as Kickback brought up, is bunk because Leo doesn't think he shouldn't hit Sela because she's a weak fragile flower, but because only colossal jerkasses hit women and he isn't a colossal jerkass.

Poor Tusk, he was forced by Yamato to smell Leo's sock. He have a very sensitive nose! How could you do a cruel thing, Yamato? You supposed to care about ANIMALS, Not torture them! You're a Zoologist!

Leo is a comic relief who doesn't want to hit womens and Sela doesn't want to be treated as a weak one because she is a woman!

So much Character-Driven this show than last few Sentai! No wonder why they abandoned Toy Gimmick for more Character-Driven

I think last few Sentai was over reply on Gimmick more than Character-Driven which could be a factor of why Ninninger wasn't a great or not very memorable Sentai.

Yeah I feel like these episodes are especially nessicary when a new show is starting up.

I'm not opposed to it, in fact it's the one potential relationship that actually works given what we've seen so far. In fact, I am kind of for it, I just don't want to see some nasty fan fiction or something like that, you know? I do think it is an interesting dynamic that could play out well in a romantic situation. Maybe for once it could actually be developed over the season unlike the one in Kyoryuger that came in out of nowhere.

Holefully, considering there's no peripheral collectable trinket to collect alongside the mecha that interacts with the changer (Zyudenchi, Ranger Keys, Hiden Disks, Gosei Cards, Shurikens) then we can get a more heavy focus on the characters than a collectable gimmick. Hell, we only have 3 accessory mecha announced unlike all the various Ressha.

Compared to Nininger's pacing which spammed out auxillery mecha back to back...

I just love this show.

Of the characters, Leo is the only one I'm not really feeling right now. He just doesn't seem to pop as much as the others (Despite his garish outfit). Amu is quite clever, but is just more willing to enjoy life rather than constantly worry about something that is out of her hands, Tusk isn't the most creative as a stoic character, but he's willing to go against the will of his team, while Sela isn't as much of a straight (Wo)man as I thought, being silly at times but also takes pride in fighting, pure and simple.
Leo just doesn't have any qualities that go against his general character.

Not to say I dislike him. He's really hard not to like, but he seems a little overshadowed in comparison to his compatriots.

I'm surprised you forgot to mention about Yamato

At least he's not screaming a lot like Takaharu! :rolleyes

Well, he's pretty cool, too. I'm a big fan of him, since he's cool headed, but prone to panic. He's stressed out, but not running around and screaming. He's really enjoyable since his reactions are what I expect. He's not running around screaming burning justice, but he's also not a wet blanket like Takeru from Shinkenger.
