Well hello guys long time
I recently completed yuela route and when i started a new game the 2.0 chars were locked.
How to unlock this?

and what route do you recommend to me?Seralwi or Emelita D:

You unlock the characters by completing the Extra Stories from the title screen. (possible spoilers)

The Serawi route is a nature loving type of route.
The Emelita route is more involved and has some surprises.

I personally went Yuela, Serawi, Emelita. (then Yuela, Serawi, Yuela, Emelita to complete everything )
NG+ unlocks a lot of extra content including dungeons, quests and characters.

And what do you recommend?
Do the others 2 routes first (Seralwi,Emelita)
or do Extra Stories first ?

EDIT: WHEN I PLAY EXTRA STORIES MY CHARACTERS DOES NOT APPEAR AND THEN A ERROR COME D:
EDIT 2: Do you think to active Party Members(Have All The Characters) in NG+ Is Better or no ?


EDIT 3:
I want to know to unlock and see the person between Wilfred Dion and Hannah in this photo? (in the story)(NO SPOILERS PLEASE) !

That's Yuela cosplaying Serika/Celica.
You get to craft those clothes for her in NG+.
And all CG under her char are related to NG+ chars and NG+ clothes

Also about side stories the spoilers are about:
Elizasleyn and Melodiana in An Angel's Melancholy.

And for one at hot springs its spoilers about:
Suina, Aht, Melodiana, Paraskevas, Crayannem, Uya, Kohakuren, Sharty and Ragsmuega. As individual characters also, a bit of spoiler for events involving:
Suina - Kohakuren
Melodiana - Kohakuren - Sharty
Aht - Kohakuren

So, if you did all the events involving Elizasleyn, Suina, Aht, Melodiana, Paraskevas, Crayannem, Uya, Kohakuren, Sharty and Ragsmuega you won't get spoiled by side stories. A small spoiler is that you get both Stone Golem and Leguna from the 2nd extra story, but that shouldn't mean anything to you until you reach Emelita's route.

There's 1 more side story, Angelic Blessing. But that's just a H Scene.


Edit: Forgot to add Crayl and Gaptahl at the list of individual character spoiling during the hot spring extra story.

And why when i play extra stoires there is a error when i start the test of leguna ?

don't know. Make a backup of your game saves and try reinstalling it.
Maybe you're missing some files. Or some of them got corrupted or... I got no other ideas

Maybe if you post the error screenshot someone better at this then me can help you

i have played the game 2 times but im not getting demonfolk rumours quest and gold alchemy events(taken data from previous game) i have tried everything possible and saw many posts but i didnt get the solution.
