guessing she's a new character?

no idea.

Hopefully that doesn't take screentime away from my unrequited crush, Moa.

:p

Guessing from the auto-translated title: REM will get a humanoid form and this is the actress who will portray her?

Something like that.

That's what I assumed when I saw the video. I wasn't sure though as I couldn't remember any other episode being teased quite like this.

Another girl joins Riku's growing harem.

The info that REM will get a humanoid form has already been out for some time. Plus Mimori is Rem's voice actress to begin with so unsurprising that she's playing her humanoid form.

Man, Geed really does just refuse to stop being so good week after week, huh? You'd think bringing Kei "Game Master in-training" Fukuide back after Belial finally showed up would feel like a huge downgrade, but this episode did a very nice job building him back up.

Also the theme songs finally switched verses, so that's something.

What is the light inside Kei anyway? Does it mean he's also carry a Little Star or something?

It is nice you can view it on Crunchyroll. It is not too bad so I am in the middle. But will keep on going at it to see if it improves or gets worse.

Saw last week's episode. Honestly, Royal Mega Master doesn't look bad per se, it's just a huge downgrade from Magnificent
