Is Babel Kyusaku coming back?

Babel Kusaku is a 5 story, 88 year old multi tenant building. Kusaku Mitsuhiro is the building's new manager. While dreaming of becoming a screenwriter, he gets lost in Babel where a false world where all dreams came true can be accessed. Like him, the tenants of Babel are all people who had to give up their dreams in the real world. Those who got lost, wish to stay at Babel forever. However, once you say the word "Babel", you can never return to the real world.
