This is the first professional release by former doujin circle SherbetSoft. Even though Kento was fed up with the monotony of every day, he doesn’t do anything to make it better. His only joy is sneaking glances at the angel-like girl Shion who sits next to him. One day at dusk, he saw her with wings on her back. As she tells him about her ‘angel sickness’, they are attacked by the ‘angel hunter’ Hiruta. He helps her escape and avoid the clutches of a man who harbours great hatred for angels.
