Demon Angel Sakura 1-4

Heaven and hell. A realm of angels, a realm of demons. - Two opposite worlds connected by a "gate", a neutral vast stretch of space. - The two worlds rarely interact, due to the negative effects of - each realm's "silk" which cripples anyone from the opposite. - Somehow, demons sneaked into heaven and stolen one of their treasures, the forbidden mirror. - Queen Anastasia calls on angel Sakura to go to hell and bring it back. - Sakura is immune to the effects of silk... but not to its many other threats!​
