Not that we can use this as a reliable source but at least a forecast.
source from Meet up
Though this won’t prevent a miko pedo or stalker to check every week 
Woah in japan server they told players about hidden class?
Sigh. whatever please add it to itos server.
because a lot of player want to change into miko. idk how many day to change into this class. (one month?maybe)
iirc, shortest time in kToS was around rough 11hours straight playing at minimum, cos’ the shrine worshiping in Orsha takes at least 5-7hours to finish, given that you don’t fail and re-try in a later time the spirit collecting part of the quest.
Time to r6 my pardoner first and come back to miko at r7 heh.
I do wonder if they delayed the miko update in itos so they could release it after fixing clap. I doubt it though.
Any reliable information from kTOS whether one can still change if you are already job 15?
You can on iTOS for Chaplain for example.
jTOS already got miko and agni necklace.
jtos got Miko already?
we shouldn’t be surprised as it is part of their culture thus those fanboys need their miko dolls to play with… ----> WILL THROW WALLETS FOR MIKO!?
I wonder how much money IMC is making with jTOS.
Why is IMC depriving iTOS?!
Have some Miko pics to hold off the pain, fellow saviours.
I believe it works the same as Chaplain
You will see miko added on your “Class Advacement” window once you complete its pre-requisites
OP has already quit and wont come back. Posted their quitting picture with all their characters deleted on discord. @greyhiem can you make a reliable miko thread?
I thought I would not be dumb, I was dumb … 
what is IMC !?? Waiting 3 weeks and nothing
Maybe because Japan version publisher = nexon(same as kr). That why they can update pretty fast?
日本のサーバーは巫女が来ました！
おかげでiToSからさよならできて嬉しいです。
じゃあな君達 過疎過疎のiToSにはもう興味がありません
lol. Post above just makes me jealous.
I wanna those cute voice JP pack too
GO to ToS folder right click user.xml>edit
Language=" ">>Language="japanese"
game now uses JP voices
profit.
You can also change your loading screen to image of your liking, just replace then rename your preferred images scale must be 1920x1080.
I do aware of that
I am on InaTos so might be different from iTos
I did check on JP voices and they are more updated. Like safety zone, they sometimes also said “mamotte”
Exorcise priest also have “Nogasanaindakara!” like that while we don’t
Or maybe it’s just our server isn’t updated yet. IDK, we don’t have R8 ATM…
Well I hope you guys get the voice files too for demn cute squeaky jp voices.
If not, Reddit will likely have some way applying a voice patch.
I can try 
or perhaps @arkgolf or someone else would like to make miko thread? I will make one soon.
I love you too Kako 
Too bad Nymemer is gone.
@Sciguma Same as chaplain, once you meet all conditions, you will see miko in your class advancement interface:
Thanks a lot!
Now I can safely level up until Miko release.
