Hi Ghost Hunt Fans!! I just found out that they will be starting a new Ghost Hunt Series!!!
Kodansha's ARIA magazine celebrated its second anniversary by launching the sequel manga series Akumu no Sumu Ie: Ghost Hunt (The House Where Nightmares Dwell: Ghost Hunt) in its September issue on Saturday. Shiho Inada is once again adapting Fuyumi Ono's supernatural mystery stories, just as she did for the first Ghost Hunt series.
In particular, the new series adapts Ono's 1994 novel Akumu no Sumu Ie; this novel serves as a followup to the original Akuryō novels that inspired the first Ghost Hunt series. Due to its rarity, the Akumu no Sumu Ie novel is known as the "elusive sequel" among fans.
