50HEARTS"Good" and "Evil", the contradicting disposition of a person mind

The integer “50” has a meaning of “half”.
All stories are developed along the oscillations between "good" and "evil" which divide the heart of a person.


Every work are created from a single drop of sound, and the stories are given birth when melody becomes harmony.
This project is based on the work of each musical track born out of such alternations, and expressed through an ideology which transcends the standard concept of music, for example with common genres or assigned musical instruments.
Each of the assembled members are masters in motion pictures, photography, literature and web production, and operate as a creative team to construct the world view of 50 HEARTS.
The objective is to transmit these works, composed entirely with English lyrics, to the entire world through the internet.


It begins with a backdrop of religious concepts, such as the Old Testament as well as ancient and existing religions, and projecting this world view through the sound of band music.
Shining a spotlight on the historical panorama inherited as the roots of society since the genesis of humanity, this group performance fuses the representations of mankind with romantic grandeur in a modern re-construction.
The entirety of each work is represented in the story of the main character's experiences through verses and melodies composed in English, expressed via a variety of forms - for example, novels - interweaving and flowing together.
Each work is a fragmentary depiction of the world view held by 50 HEARTS, and with the birth of each work, the story continues to expand.
This project is simultaneously a creation, page by page, of the gospel woven together by 50 HEARTS.
