There is probably some kind of 'cooling off' period between each suicide. I'd say at least a week or two.

But between then, we can have Botan and Kuram busy themselves with other concerns.

The rest of the day would be uneventful, people have calmed the fuck down by now. I'd say the final bell with them walking home and talking, them cleaning up the greenhouse and talking, or them arriving home, all work for me. They'd probably just talk about the minimal immediate findings, their ruse, other minor demon activity in the neighborhood, etc.
