Ruka Ishikawa

Sumiko is a university student who is blessed (or suffers) with a special ability to instantly grasp the BPM (beats per minute) of almost anything. One day she meets a boy who inexplicably sends her own BPM off the charts!

Ichiko Kawanabe (Hana Sugisaki) has lived with her boyfriend Yoshinori Hasegawa (Ryuya Wakaba) for 3 years. Yoshinori proposes to Ichiko but the very next day Ichiko vanishes. Yoshinori, unsure of what to do, is approached by a Detective, Shuji Goto (Shohei Uno) who shows him a picture of Ichiko and askes where she is. Yoshinori goes on a journey to find her, meeting people who have known Ichiko along the way and pieces together Ichiko's shocking history. (Panap Media)
