“To be honest, we did have a child a long time ago. A child shinki… I realized that Daikoku always wanted a baby, so I found one and named him "Mamoru”. I took a character from Daikoku’s own name, so we called him “Daigo”. And we lived together just like that… for one-hundred years.“
Shogo Sena’s character is based on Love Stage!! mangaka Eiki Eiki’s little brother DAIGO (rock singer). DAIGO also provides the voice for Shogo Sena in the anime adaptation. Eiki Eiki-sensei and DAIGO are grandchildren of the former Japanese Prime Minister Noboru Takeshita.
