Well with the service and two students dead, I'm pretty sure the school MIGHT have closed for the day due to how shocking and sudden it is that two students who have shown nothing but excellence are dead. The funeral can take place in the early afternoon, leaving Botan and Kurama to go grab something to eat at a cafe, so I'm down for that idea. 

The couple thing works and helps give them the excuse of being together all the time--and yes, he'll tutor poor Botan in their spare time so she can better blend in, but be warned I know jack shit about anything other than storytelling, so we're gonna need to just imply how super smart Kurama is xD but Botan being the hot new girl and Kurama already got her? Damn. She's gonna be the girl that those two basic bitches talk shit about in the Baby Got Back video.

"Oh. My. God. Miku, look at her butt, it's SO big--" lmfao just straight up hating on her grim reaper self.
