赤の原遊戯 (ワシュピール)
NOTE : was released as a stand alone in 1993 by Biblos, and ran in BexBoy Magazine. When Suguro moved to publisher Taiyou Tosho in 1999, she continued the story in their Craft line, and closed it up as part of the second Aka no Washupiel in 2000.
Kinda creepy. Dante, the main character, is fighting various characters to keep the passage to the demon world sealed, but he doesn't seem to be having much luck... (And the story says 'To be continued' at the end, so there might be more to it.)

Dante is a demon slayer and bounty hunter with a demon heritage of his own that haunts his past. He's currently unemployed--and bored to death. Opportunity knocks in the form of a missing-child case, which his friend and manager, Enzo, offers him. But a four-million-dollar reward, an unexpected demon attack and a little girl named Alice all conspire to send Dante through the looking glass on a nightmarish adventure beyond his wildest imagination.
