I know that vol.4 was relesed in japanese.. therefor vol.3 is not the last one.
Ouh does that mean chapter 22 is in volume 4??
I suppose.
I can tell you that i've ordered Vol.3 in english but it havn't arrived yet. The last time i've checked it was out of stock on Amazon..
And i tried to search for Vol.4, but i can only pre-order it ( for Jun or something like that)
vol 3 is until chapter 15~
can someone tell me third volume consists of how many chapter and does it include chapter 22 which is the latest chapter as of now because I'm planning to buy the physical book
