Demian Shoukougun - Demian Maiden (Doujinshi)

Ralph can see angels and demons. When he was five years old he came across the winged demon Valafar and was completely charmed by him. He made a pact with the demon in order to make his wish, to live with Valafar, come true. Seven years must pass, and there are two conditions that must be met for the pact to be fulfilled. Can the older Ralph discard his ties to humanity and fulfill the pact…?

A short doujinshi that ties in to an event at the end of Demian Syndrome volume 4. It doesn't focus on the event, so the doujinshi is more a tease than a spoiler.

Azuma and Takayama used to be really close friends as children, until one day Takayama disappears to the USA without telling Azuma. Unable to forget about Azuma, Takayama returns years later and enrolls in Azuma's school. He finds his old friend cold and unwilling to restart any kind of relationship… but why? Takayama is a light hearted, happy guy who gets along with everyone around, even though Azuma's odd behavior hurts him. Azuma is cool and distant, and seems not to care about anything around him…
