This is what a guy called Meddon1 has translated so far from the live stream
"I'll see what I can translate but obviously I'm more than 20 minutes behind.
The text underneath the video says that they've invited a gamer guest (羅康妮, left girl). 希兒 (the presenter, right girl) will attempt the White Dragon trial.
Stay tuned!
They start off introducing the guest, talking about FFXV, she's up to Chapter 4, but she says she could've spent a night just fishing in game......
希兒 tells us that Noctis is coming, but she hasn't said when yet. Noctis' Limit Burst is something to do with his mirage swords(?). He will have a very strong ST physical attack, and also gets a self-buff that boosts his ATK/MAG/SPR.
Noctis will also get (this is his 5* lvl 80 skill?) a Jump-type skill to mimic his FFXV "instant movement" attack, and will be able to regen HP and MP.
There will be 3 other units on the banner. Charlotte (5*) (希兒 says she looks like a cute cheerleader), Mercedes (premiere release) and Chizuru (2nd banner). She talks about some of her 6* skills, so presumably she will get her 6* awakening this banner. TL;DR: This banner will be 5* Noctis + 4* Chizuru + (4*?) Mercedes + (3*?) Charlotte, so get out your wallets.
They start chatting a bit about FFXV again, saying female gamers really enjoy the FFXV boy band and male gamers bemoaning about the lack of female characters. They talk about how you can just randomly talk/listen to passerbys(?). I think I'll stop reporting the chit-chat.
羅康妮 is an newbie at rank 7, and 希兒 teaches her about the Chambers and Missions. They try to enter Colosseum (lel) but obviously she hasn't gotten to Grandshelt yet. She has some lv 6 units lol....... 希兒 continues to talk about Roselia (she's a nice healer) and Trust Master Rewards."
I believe though that they later did confirm that noctis announcement will be tomorrow, while his banner will be on the 16th, so pay no attention to the part where it says they don't know when.
