[Frontier]

Nothing more validating than a doctor Humagear fighting the Metsuboujinrai hacking to be what he was meant to be, a doctor, and saving a human who hates Humagears. And while you knew on some level it was going to happen, the episode did a great job ratcheting up the tension so it would genuinely feel touch-and-go there.

It's nice seeing beneath all their bickering how much Yua cares about Fuwa.

I like seeing some of the prototype "naked" Humagears in Aruto's Zero-One headquarters. I never really thought of it before but a secret place in his office gives me kind of Batman vibes.

Breaking Mammoth! I guess your feelings on it probably depend on your feelings of Mecha in Rider, especially when obviously CG entity is obvious, but I thought this was a pretty cool sequence and to be honest I find mecha Zero-One kind of cute.

"Zero-One...you do seem to defy our calculations" Man I love it when the bad guys start recognizing the hero wrecking their plans. I mean, that whole scene of Aruto showing up and making a one-man stand with the Opening is such an epic climax.

Yua thought she and Is were building a good rapport and relationship and then Is is like "I know you screwed us over." Kind of a shame, although Yua brought it on herself.

That was a nice Aruto and Fuwa moment to close this arc up.
