This is GhoSTory by Kaijitsu (Fruitz)
a webcomic from back when he was still apart of the group, FCLG,
which has long been disbanded since 2015.

Unfortunately, the chapters have only been translated in English to chapter 7 by Rou & Omegalupus
while the Japanese version has been completed here:
http://e-hentai.fbk.tokyo/index/g/1365555/e5bcf25add/

Character bios included.

Enjoy!

Would be nice if the rest of the story was translated from where it left off, I could do it, but I don't think my editing skills are worth it =.=';

It appears ch7 is missing a page.
