In a small school in a small town there is a classroom unlike any other. Shiroi Hane Girls Academy. Classroom 2-1. The students nicknamed this classroom “Second Heaven” of “Angel Classroom” because all of the students are angelic, beautiful, and talented. That is all of them except for Natsume, who just blends in with the background, and is as normal as you can get. Because of this, she has been given the nicknames “Normal Natsume” and “The Devil of Angel Classroom”.
One day, she finds a red ribbon, and decides to put it on, in the hopes of making herself stand out a bit more. What she didn’t know was that the ribbon was enchanted to summon an impulsive succubus name Amaranthe, who, through the power of the ribbon, is stuck on earth until she helps Natsume become more popular. With Natsume’s former best friend Masami’s help, the three of them are now on a romance-filled quest to win the hearts of their fellow classmates, complete with devious bullies, prideful angels, evil succubi, and a robot maid.
This won’t be easy for either of them.
