The pitch
I met my childhood friend again, and she had become a beautiful and innocent girl.
"It's been a while, Hayato."
"Haruki, is it?"
In the past, I used to play in the mud with my childhood friend in the countryside, and when I saw him again, there was no trace of the bratty young man I thought he was back then. Only in front of Hayato, she threw away the coat she was wearing and reacted in the same crass way she did back then. The distance between you and me has not changed.

Should it go on your list?
If you're someone who slots comedy register shows on principle, Tenkou-saki no Seiso Karen na Bishoujo ga, Mukashi Danshi to Omotte Issho ni Asonda Osananajimi Datta Ken is an automatic add to the first-three-episode try-list. If the light novel resonates with you, that doubles the case.
What to watch for in week one: animation density of episode one (premieres usually peak there — does episode two hold?), how the Project No.9 team handles the first big set piece, and whether the OP/ED give the show a sonic identity beyond the source's existing fan signaling.
Slot it for the first three episodes. If the production's holding by week three, you've got a season-runner.
