I think even then there will be dissatisfied with the gender of the team leader. In this regard, RizCta is probably the most fair, the sequel / spin-off of Girls x Heroine, where most of the team is a girl, but the main character is a guy (and even the poster hints that he is not).

(Yellow, Black, and Gold/Silver are all female)

There's also a Sentai that fits this description, albeit an unofficial one.

By the way, I saw a rumor that the theme of this season will be not only kings, but also insects. I highly doubt its authenticity, but it's worth mentioning just in case.

The insect theme rumor has been going around for a little bit, even before we got the series name.
I don't know it's validity, though. While I would like to see it, I'm not gonna hold my breath.

When will the first look be up?

in next month.

Wait, next month's scans, or not until December?

that's right is until December.

Found this online. Not sure what it translates to
