Toriko no Yugami ~Ondai Sotsu no Moto Utahime ga Hibikaseru Midara na Nakigoe~

Yuusaki Shion, the manager of Café&Bar Amulette, runs the establishment left to her by her parents, who died some years ago, and lives with her sister Kanon. About two years ago, they began living with their cousin, Uzuki Hina, who had arrived to attend a local university. After Shion graduated from a musical college, she worked as a professional singer, but after her parents passed away, she focused all of her attention on managing the café. She was spending these hectic but somewhat happy days, and so only one month was left before the annual charity performance hosted by her childhood friend Minato Nami started. Nami, like her mother, had been good friends with her since they were children. Shion and her parents have also set up a food stand to support their concert. The time before the concert was busy for Shion, so she decided to hire a temporary cook. One day, Nami came to the café and asked for a favor: to perform at the concert. Nonetheless, the protagonist has not been practicing singing in order to retain the café her parents left her. Even if she has been a professional singer for some time, she would need to practice before singing in public. Fortunately, the temporary cook was found, so Shion was able to both manage the café and sing at the same time. Kaon, Hina and Nakanomori Kyouko, a fan of Shion, encouraged her to perform. Despite her worries, Shion worked out a solution. Little did she know that, after her decision, a nightmare was waiting for her. [Translated from the official site]
