It seems the English version of vol 4 will be released later this year ^^
OMG THANK YOU SO MUCH!
Wait but how do you click the chapters?
You're welcome ^^ For Futekiya, it requires you to subscribe first before you can read it. It costs $7/month, but you can read all the manga on there in that one month and then unsubscribe.
For the raws, you can just copy and paste the link ^^
Ohhh thanksss againヾ(☆▽☆)
Is there already a vol 3 of this raws?!
