Moon Eyes Cat is an electronic rock VOCALOID song that depicts the theme of discomfort and uneasiness as if someone is watching you. Composer and VOCALOID Producer Wataru Sena drew inspiration for the lyrics, composition, arrangement, and mix from the world of today's surveillance society, and used Miku Hatsune as the vocalist to express a somewhat cold-hearted yet emotionally leaking expression. The addictive and catchy melody and the lyrics, which are easy to understand but somewhat meaningful and implied, will catch the listener's attention. We hope that this song will resonate even a little with people who are engaged in some kind of activity or struggling with relationships.
