Synopsis: Spill It, Cocktail Knights!

Kirameki City is under attack by terrifying beings called Stressmen, born from the accumulated stress of its inhabitants. To fight back, the Cocktail Knights, a quartet of powerful sorceresses, have emerged. Their identities, however, are a well-kept secret known only to a select few. Riku Daichi, a high schooler, counts himself among that group and knows that his best friend Sora Amagami is actually Valencia, one of the Knights. Riku is devoted to Valencia, and his love for her is no secret. However, he tries his best to keep her true identity hidden, a task that becomes increasingly difficult as Sora begins to develop feelings for him. Unaware that Riku is privy to Valencia's secret, Sora's growing openness about her emotions only adds to Riku's predicament.
