About the brush gods, I thing they could be on both games, because they are almost same, but only that Okamiden have Kyokugami (god of magnesium).... maybe all other except the Michigami (penguin) are taked By demons. And Michigami is the god who gives the twins the power of guidance, which will help them to find the other rebirth brush gods.
And the rebirth one could be any kind of a animals maybe.

I can make a list of the brush gods rebirths and edit it as much as the slots are open. most likely first come first serve. And there could be others charasters as well.
And I think there could be not limits how many charasters one player can play, but the brush gods slot are first priority.

Rebirths
Yomigami, Tachigami, Hanagami, Bakugami, Yumigami, Nuregami, Kazegami, Moegami, Kasugami, Kabegami, Gekigami, Itegami, Kyokugami

(If there is not enought players, maybe some of them could be gived like a some evil bosses, when killing this boss, the brush god could be revived?)

Ok, thanks. I had some ideas for the brush gods, but I wanted to make sure I was using the right ones.
Also, I think the brush god rebirths that are not under the demon's controls should be the first brush gods you gain in both games, which are Michigami (Pinguin/Guidance) and Yomigami (Dragon/Rejuvenation). Like you said, Michigami helps to guide then and Yomigami can help to "rejuvenate" the brush gods to be good again. (Or something like that.)

For the rebirths, I was thinking that they could be the animal that represents the brush god. For example, Tachigami's rebrith is a rat, since Tachigami is/looks like a rat.

Yeah. Also, do you think the brush god rebirths should have their own names? If so, then the person who owns the brush god rebirth can come up with their own name.

(Well, if someone wants to play as a boss, they can, but I think bosses are more like NPCs, which are played by the owner of the RP in most RPs.
But, we can do that. We just need to think of bosses now. The main boss can be played by you, since you are the creator of the Rp.)

Well It totally fine with we if the brush god rebirth are as their normal animal form or then they could be different animals, but still rebirth of the brush gods, but still close to the originals (of course there is some whish need to be same, like Moegami user of fire could be like it is a Phoenix? or some big bird)

And I think their calling name could be something else (but their brush god names will be same) because they are rebirthed they have not parents, they are maybe adopted By some one (get name By them), survived By themselfs (named themself) or totally have amnesia and do know anything after the rebirth happens, not who they are,where they are or why they are there. something like that.

(and there could be max 3-4 bosses, played By whenever want them or By me. and there could be thoise little demons which anyone can play, and they are killable ones. Dropped after using)

Yep. They can, or course, use the same powers as the brush gods, like Moegami's rebirth can use fire.

Yeah, and the player can come up with their name, if they want to.

Also, I was thinking, since I think you said the brush god rebirths where spread all around Nippon, I could give you some ideas of where I think the rebirths should go.
For example, Tachigami's rebirth could be found in the Cave Of Nagi, or somewhere in Kamiki Village,
Itegami's rebirth could be found in the Wawku Shrine or somewhere in Wep'keer, or Ezofuji, ect.ect.

(In the first game, there was about eight-seven or so bosses, and in the second game there was about ten bosses, so think we should have 5-6 bosses.
Demons are more like NPCs, but they could be played by other players. Maybe we could have some players that play as just NPCs, such as shopkeepers, demons, and other people, if they want to.
Then again, that might be a bit hard, but we could try.)

Yes, but only about the 5-6 bosses, they need lots of players, so do rebirth ones... or then players can rp like a two bosses + rebirth one as a same or different time, but of course the bosses will show up different times. (it's could be little too interesting if there is like two bosses to win xD)

And shopkeepers + others could be too played By anyone, because they are tecnically background chars, and usual only show up when somebody go to shop. and then if the player 1 char, decised go to shop, player 2 can play the keeper part if wants.... ) or then the one who go to shopping will so called dissapear for a while, and come back with the stuff it buys...

Well, since a player can have up to 2 characters (If you want to add that rule) One player could have 2 bosses, so there would be 3-4 bosses left. Depending on who the player wants, the amount of bosses should be fair. If we don't get a bunch of players, we can just hand out the others to other players.

Well, I think we the players come to join, we should ask then if they want to do that. Like I said, it might be a bit hard, so not everyone will want to do it.

Yes, that could be good idea, and about the bosses they can either way to be canon bosses as a rebirthed ones (well all the bosses for both games, lot likely died so maybe the final boss used some "dark magic" to get the canon bosses back to life or something like that) or then the bosses are totally new ones... player can choise the look to their bosses.

And Amaterasu, Chibiterasu, Shiranui (dead) could be all background charasters, probably played By nobody.

Well, since we already sorta have the rebirth theam going on, that would be a good idea. I think, depending on how many bosses we want, half could be rebirths and half could be new bosses that the player who chooses to RP as a boss can come up with, unless you want to come up with the original bosses yourself.

Yeah, and the original brush gods too, maybe. The background characters could be played by you if you want them to interact in the RP.

It could be fun with the new bosses, but of course anyone just don't want to create a new ones....so the original bosses will be "rebirted" only when they will be used.

(But only one boss Yomi/ Akuro could be not used to this rp and never ne rebirthed...because it was like the stronges villan to the games and there is still the random final boss.)

Yeah. So, which bosses should be rebirthed? I'm thinking Blight, Crimson Helm, Mizuchi and/or Ninetails (Since you said you had a rebirth already in mind for her.)
