Only this time
Takuto and Miyakawa-kun had previously released a single together, but they weren't a unit yet. They got the opportunity to sing another song as an opening for the anime Meitantei Conan, and they decided to form a unit for their work together.
The name Only this time was proposed by Miyakawa-kun, with the idea that there are things that can only be done in the moment; and they as creators have to take care of what they create.
