Who are all the recruitable characters? In all story lines? Because I know that some characters in this game are super awesome and I want them!!

If this has been answered... I didn't see it.

[Silverevilchao]

ALL of the characters you could possibly recruit in the game consist of:

Izuna
Amane
Gin
Kaido
Naoya
Midori
Keisuke
Black Frost
Mari

...assuming I didn't miss any. I don't think I did.

[Archie55]

Awesome!!!! Looking forward to Black Frost... Although I don't think that he's gonna be in my round now... Cuz I kinda didn't do something that I think would cause him to appear. Oh well.

[Yuidirnt]

To make Black Frost available you have to see a event with a Jack Frost and Midori on the fourth day (If I'm not mistaken).

[Archie55]

K, so I missed that. When I'm going through it again, is it marked, or do I have to go somewhere and it will say ???, or something in blue?

[Darth Xelleon]

Izuna's recuitable? Isn't she that military girl?

[Archie55]

Yeah, she's the military chick. She can be recruited. I've seen it.

[Sakai]

For Black Frost during the fouth day just attend ALL of midori's event's.
Then protect Black Frost and his demon friends on the 2nd last day if im not wrong.
Izuna will be recruitable if you go via Gin's route.Practically everyone BUT kaido and naoya will join you on that route.You can only recruit naoya and kaido in their routes.

[Elexq]

Izuna will also join on Atsuro's route, but no one else's besides Gin.

Yeah, Gin is the man. It's a shame that you're required to use Atsuro for the final battle, I wanted to use some of the other characters :/

[Sakai]

:l Exactly.
Gin ftw
