Concept Story

The employees of Tanseisha are all unique individuals who thoroughly enjoy their work.
As a result of pursuing their passion to the extreme, their individuality transcended the boundaries of what is considered human.
Eventually, they evolved into "Tansei people."
And finally, they managed to establish their own planet, "Tansei."
Today marks the 80th anniversary of the settlement of "Tansei".
In order for the Tansei people, now renamed "Tansei people," to undergo further evolution,
It seems they are looking for new personalities and ideas.
Come on everyone, join the festival!
Why not connect with the people of Tansei and paint a vision of the future together?
