Syuuko Okimoto (沖本秀子)
The real name of the comics creator better known as Shu Okimoto (オキモト・シュウ). The mystery title Naniwa Shounen Tantei Dan (浪花少年探偵団) was released under this name. It was based on the novel series by Keigo Higashino (東野圭吾) and published by Akita Shoten (秋田書店).
Her name was once listed as "Hideko" in Akita Shoten’s author database, as well as other sources. It was, however, written as "Shuuko" in at least one issue of Susperia Mystery (サスペリアミステリー) and appeared to be romanized as "Syuuko" on the cover of this Susperia Mystery Comics volume, which is why the last transliteration is used here.
Youko Okutoba (奥鳥羽洋子)
Alternate pen name of adult comics artist Hiro Kannaduki (神無月ひろ). One volume was released under this name, Jigoku no Baby: Akuma-chan (地獄のベビー 悪魔ちゃん), published by Leed Sha (リイド社) under SP Comics - Kyoufu no Yakata Comic Series (SPコミックス・ 恐怖の館コミックシリーズ).

Rei Ouma* (逢魔麗)

Iku Oyamada (小山田いく)
Comics writer and artist. Brother of Yoshihisa Tagami (たがみよしひさ), he also released works under the names Katsuhisa Tagami (田上勝久) and Yuya Ando (安藤優弥).
A Susperia ad once described Oyamada’s works as "heartful horror," and, as strange as that sounds, it’s actually quite appropriate. His works have an underlying sentimental tone, which the horror elements happily keep from getting overly saccharine. Although Oyamada seems to be better known for his boys’ titles, I highly recommend his girls’ horror!

Ryuuji Ryuusuke* (竜介龍司)
I haven’t been able to confirm the reading of Ryuuji Ryuusuke’s name. Given that there was only one title released under this name, it’s unlikely any confirmation will be forthcoming!
