Historical Notes:
The Heisei Era corresponds to the reign of Emperor Akihito
from January 8, 1989, until his abdication on April 30, 2019. https://en.wikipedia.org/wiki/Heisei
The (current) Reiwa Era corresponds to the reign of Emperor
Naruhito (Akihito's son) from May 1, 2019, to the present day. https://en.wikipedia.org/wiki/Reiwa
Bonus Points for Youta-kun giving more serious thoughts to the future than the average MC in an H-Story is portrayed as doing. That and more adding up to a Most Excellent FAKKU Debut by this artist.
