Adekanfan (translator) has already dropped this while Devilcastlescan (now Frankenstein*something*) also stopped buying and scanning this because they no longer see any reason to continue..
The latest chapters are about them getting out of that place and new arc which was so anticlimactic..
Yeah, I also kinda dropped it because sensei kept pushing the girl x shiro ship.. but I still keep in touch hoping that there would be a breakthrough with Kojiro's mystery..
I wonder what happened
