  • 「Quadratic Playground」概要

In the age of diversity, we created a field called “Quadratic Playground” to create a place where each person can create questions and answers that value the feeling of fun. It is an attempt (playground) to create new entertainment by combining various technologies and expressions.

First of all, in three genres, MUSIC, SPORTS, and WEB CM, we will develop content that allows you to experience the catch phrase “Answer that is more fun than the correct answer.” MUSIC plans to release a VR music video in October that will allow you to immerse yourself in the world of 360-degree music, along with the unit “YOASOBI” that turns novels into music. SPORTS, together with former Japan national football team Atsuto Uchida, plans to release educational VR content in November that allows you to experience the thoughts and sensibilities of soccer play from your own perspective.

YOASOBI comment

It’s a song that is packed with timeless love romance and important feelings for important people who can’t meet even today. It would be great if you could feel the MV’s running feeling and the love that runs through, with a world view that is unique to this song.

We received the straightforward feelings of the two people who jumped over the gap of 100 years and fell in love from the original, and put their voices one by one. It would be great if you could fully enjoy the appearance of the two people asking for their thoughts to go against their destiny, along with the music video.

Comment from Eisaku Kubonouchi

While listening to YOASOBI’s music and the director’s production plan, I expanded my image of how to visualize Chiyoko and Tokisho, who connect their hearts with only timeless letters. The error of 100 years and the error of 100 seconds are the same as the frustration that cannot be connected, and they are the two who extracted the pure and ephemeral love.
