The pitch
The 1910s. Iwamoto Kodo, a student at Suho Junior High School under direct command of the army, is investigating paranormal phenomena across the country as per military instruction. In a village rumoured to have "black snow," he meets a boy with special powers who believes them to be an illness; through Iwamoto's support, he realises they might have something in common and receives a recommendation to the school. Mysteries await Iwamoto at each place he visits–a romantic tale of this era begins to unravel!

The read
If you're someone who slots supernatural register shows on principle, Iwamoto-senpai no Suisen is an automatic add to the first-three-episode try-list. If the manga 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 Studio Deen 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.
