Kawai Maria transfers to Totsuka High School after being expelled from her previous school. Upon entering the classroom and hearing the students gossip, she bluntly states that the reason for her expulsion was an act of violence against her former teacher. The sharp tongue and frank nature hidden under her pretty face immediately makes her an outcast among her classmates. After all, she was told that she "taints others." Nevertheless, Maria hopes for a fresh start. She manages to become close with two of her classmates after they hear her beautiful singing. One is Yusuke Kanda, who's kind and friendly to everyone on the outside, but inside isn't that way at all. He teaches her a "lovely spin" which should help her get along with others better, but it just makes her seem even more intimidating. Maria, apparently, isn't a "lovely spin" kind of a girl. The other is Shin Meguro. He is tall, dark-haired and always frowning. Coming from a family of musicians, he knew right away which song Maria was singing. Meguro is a returnee but Maria points out that because he lacks communication skills he doesn't really know how to speak English. Throughout the year Maria faces many problems, mainly relating to getting along with others but soon resolves it with the constant help of her friends and bluntness.
Adapted from the manga "Akuma to Love Song" (悪魔とラブソング) by Toumori Miyoshi (桃森ミヨシ).
The story is based on the life of a japanese composer named Yuji Koseki from Fukushima in the Showa Era.
In 1909, a long-awaited baby boy was born to a family which has run a dry goods store for generations in Fukushima Prefecture. He would later become the talented composer Koyama Yuichi who wrote many famous songs. Although Yuichi was brought up as the heir of the business, he was rather dreamy and considered a child with no redeeming traits by the people around him. However, when he encountered music, it sparked joy and unleashed his gift in composing music through self-study. As a youth, Yuichi secretly put his name down for an overseas songwriting competition. This would change his destiny. He won runner-up for the song he entered for the competition. As a result, he got to know a female student who wanted to be a singer. Despite the long distance between them – Fukushima and Toyohashi – the two of them tied the knot. When they came to Tokyo, they met all sorts of people and weathered a dark period to produce a number of hit songs. However, war broke out and Yuichi had to compose wartime songs at the army’s request. It pained him that young men died in battle after singing the songs he had written. After the war, the country began to recover amid the chaos. The couple made a new era of music in an attempt to encourage the wounded through the power of music.
