[Itsuka Shidou's Backstory— I]

Itsuka Shidou's first memory of ever watching on tv was with his dad. He could clearly remember his dad, saying something along the lines of 'I named you after that guy. The character on the screen was your average teenager who was thrown into a fantasy that he didn't know existed. He was then tasked to talk to spirits of sorts with the help of a crew who tells him the most optimal words he could say while conversing with a certain spirit. By the end, the agreement would be sealed with a kiss, and then it's over. 

At first, Shidou didn't get why something like that was happening. He even thought at one point that everything shown on the television was real. Well,  one couldn't really blame him since he was still five years old at that time, barely awake to the reality of the world. Kudos to his father though, for letting him watch a series with a harem tag even though he was just five... and not only that, he even named him after the character.
